P and B, Start– or Refresh with These Speech Sounds
Today we begin the series of recommended sequence for consonants and vowels.
Deliberate and focused practice is best. Imitation is the easiest way to learn. Watch, listen, and do! Accuracy is everything!
This FIRST speech tip is our chosen Number 1 for systematic learning. Brain organizerer is that the Quick speech sounds in English are p, t, k, ch, b, d, g, j. The first four have no voice but in American English have a loud puff of air. The second four have a voice.
For deliberate and focused practice, make the word loud, especially the consonants. that I am focusing on.
Speech is words, and all words have vowels. So you’ll get accurate practice for those in this word.
Positioning of the lips for p and b is everything.
For American English, make the muscles in the lips press together hard and open quickly for the p and b.

How Long Does It Take to Become an Elite… in Anything?
Popular knowledge says 10,000 hours of practicing the correct way. That was popularized by Malcolm Gladwell in his bestseller Outliers: The Story of Success in 2008.
Popular knowledge talks about years too – 10 years to become an expert. The first to say that was Herbert A. Simon (Nobel Prize, 1976) and his colleagues who estimated that expertise took learning approximately 50,000 chunks of experience (Rose, Greg, 2013).
Decades of scientific investigation indicate that the 10,000 hours of practice is the average for world-class musicians but not every skilled profession. Vladimir Issurin, 2017, in Sports Medicine reported the following: Exceptionally talented athletes in endurance, power and combat sports achieved world-class status after 7 years of specialized preparation, doing 3,000-7,000 hours of purposeful training. On the other hand, Olympic artistic gymnastics champions achieved world-class status following an average of 9.7 years of specialized preparation, doing an average of 8919 hours of specialized training.
A 2019 study published in Royal Society: Open Science of 13 violinists found that the less accomplished violinists had logged an estimated 6,000 hours by age 20 while the good and best had both logged around 11,000 hours, reported authors Brook Macnamara and Megha Maitra. So the number of hours did not account for all the differences.
There is evidence that a combination of genetic factors, environmental factors, their interactions, and motivation, practice, and opportunity goes into mastering a skill (Macnamara, Maitra, 2019; Issurin, 2017).
Here’s more. In Tim Gibbons and Tammie Forster’s landmark study for the United State Olympic Center’s Athletic Development Program, “The Path to Excellence,” they researched the development of U.S. Olympians who competed between 1984 and 1998.
A few of their conclusions:
U.S Olympians began their sport-specific participation at the average age of 12.0 for males and 11.5 for females.
Most Olympians reported a 12- to 13- year period of talent development from their sport introduction to being placed on an Olympic team.
Olympic medalists were younger –1.3 to 3.6 years — during the first 5 stages of development than non-medalists. This suggests that medalists were receiving motor skill development and training at an earlier age.
US Olympians played an average of 3 sports between ages of 10 and 14 (Dr. Brad DeWeese, USOC, 2014).
According to Greg Rose 2013, the 10-year-rule has been shown to also apply to the development of expertise in other domains, including music (Ericsson, Krampe, & Tesch-Romer, 1993; Hayes, 1982; Sosniak, 1985), mathematics (Gustin, 1985), swimming (Kalinowski, 1984), distance running (Wallingford, 1975), tennis (Monsaas, 1985), soccer and field hockey (Helsen, Starkes & Hodges, 1998). Data suggests golf is a 20-year developmental sport, not 10 years. Research by PGA of GB and Greg Rose came up with an average of 21.5 years to become a winner on the PGA or European Tour.
The 10,000 hour rule is still highly debatable in the research (some show 4,000 hours, some 6,000 hours) but all studies indicate a significant investment in time is required.
Much of the debate about how many hours is required to master an area is due to lack of agreement between experts on what they consider practice. Is any type of repetition practice? What is correct practicing?. I’ll get to that later.
Soooooo, this is an article directed to nonnative-born speakers of English. What does all this have to do with successful acquisition of clear American English Speech and development of mastery or expertise? Typically nonnative-born persons get an average of 5 to 7 years of English instruction in their home country. All of that counts toward development of expertise and mastery. Also recall that the U.S. requires formal schooling from age 6 to 16—all of which is conducted in English. Those 10 years are viewed to be minimum for acquiring English communication skills for work and social life through the person’s lifetime.
Furthermore, Clear Talk Mastery measured average English speech intelligibility for the initial diagnostic assessment for almost a thousand people since 2000 to be 34%. Compare that to the native-born U.S. A. person’s average score of 90% when speaking casually and 95% when instructed to speak clearly. Written and oral interview for each adult nonnative-born person doing the initial diagnostic assessment clearly showed that the type of English instruction and the kind of practice is vastly different among individuals and between countries and within countries (63 different countries).
Recall that debate for how many hours it takes to master a domain (such as sports, music, mathematics) is due to the lack of agreement between experts on what they define as practice. The range from 2% to 83% for the initial diagnostic assessment (average 34%) for English speech intelligibility is likely an indication of the kind and quality of previous instruction and practice for English language, especially speaking clear English. And it is likely due also to other factors, a combination of genetic factors, motivation, and opportunity for speaking English.
There is general agreement about the kind of practice needed by kids (and others) if they want to get better. I’ll get to what a comprehensive review of this topic uncovered.
How Long Does It Take to Get Accurate and Clear English Speech?
How Long Does It Take to Get Accurate and Clear English Speech?
On average it takes about 70 days of practice every day to change or form a daily life habit (Frothingham, 2019). The range for daily life habits is 18 to 254 days according to a 2009 article in the European Social Psychology by Lally et al. It depends on the habit. For example, it takes a shorter number of days to form the habit of drinking a glass of water with breakfast than to automatically engage in daily performing 50 push-ups before breakfast. Notice the phrase in the first sentence “ it takes about 70 days of practice every day.” It goes without saying, the amount of time to acquire a habit also depends upon the person.
Speech which is easily understood by others is called Clear Speech. Acquisition of clear American English (AE), Clear Speech has been investigated since the 1920s for native-born AE speakers (Denes & Pinson, 1993, Smiljanic & Bradlow, 2009). Not so much investigation has been reported in journals for nonnative-born speakers for American English (Smiljanic & Bradlow, 2009).
Antonia Johnson put together the research for her dissertation in 2000 for the mode or style of AE Clear Speech. That mode or style of speaking includes greater speech volume or loudness, aiming for accuracy for all words, clear enunciation of consonants and vowels, and not slurring words together. These strategies are consistent with the Task Dynamic Model of Motor Control and Task Dynamic Model of Speech Production (Kelso & Tuller, 1984, Saltzman et al, 2010, also see Parrell et al, 2018).
Both Casual Speech (“every day” speech) and Clear Speech are styles or modes of talking. So both Casual Speech and Clear Speech are coordinated manners of talking. The difference between these modes ia comparable to the differences for muscles and movement in human walking compared to running.
For native-born AE speakers, the characteristic of enunciating speech sounds when doing the Clear Speech mode or style targets feature enhancement of AE speech sounds (Kelso & Tuller, 1984, Smiljanic &Bradlow, 2018). For instance, native-born speakers of North American English automatically emphasize the lengthier duration in time for the SH speech sound compared to the CH English speech sound, and they emphasize the lengthier duration and the two speech sounds for the English long vowel O compared to the short vowel O.
Importantly, when nonnative-born speakers engage in the strategies of Clear Speech, unless they are deliberately taught which English speech sounds require feature enhancement and how to produce accurate AE speech consonants and vowels (not produced the same in their mother language) the result is not greater speech intelligibility or understandability, Instead the result is only louder words and sentences in which the speech sounds continue to be errors for American English and continue to match the speech sounds from their home or mother language.
Our work at Clear Talk Mastery has found that forming the habit of using the strategies of Clear Speech along with the requisite or needed feature enhancement (also called accurate enunciation or pronunciation) for the 23 or 25 consonant and 14 vowel sounds on average takes 70 days. Learned and habitualized is the dynamic task of the Clear Talk Mode in American English. For intelligibility and understandability, those skills are most important.
Once those highest priority habits have been acquired, then other skill sets can be added systematically. That’s because proficiency in English intelligibility or understandability and communication includes other skills, notably core skills for pronouncing multiple syllable words. These skills include English written word syllable division rules and patterns. Crucial also for AE proficiency is acquiring AE word syllable accent stress for multiple syllable words. American English word syllable accent stress is different than, for example, Spanglish, Chinglish, Indian English or South African English.
High priority for a wide variety of persons at their workplace is acquiring the American English speech characteristics of voice inflection in sentences ranging from a few sentences needed for talking in a meeting to many sentences in a presentation. The overarching purpose for the dynamic task of the speaking style with voice inflection is to enhance or improve the listener’s memory and understanding of information.
The most practical purpose of using the voice inflection patterns is so that your speaking is not monotone and boring.
The economic and career advancing purpose is that experts say that voice inflection (and asking questions) are the two skills most important for native-born persons for advancing their career. We think the same is true for nonnative-born persons for their career. So we teach that skill in Level Two and higher levels.
Because information giving in meetings or explaining information in English is a minimal requirement for all work situations requiring English, mastering the characteristics of optimal or good presentations are the logical next step after the acquisition of the core American English speech skills for intelligibility and using the Clear Talk Mode of speaking which includes accurate enunciation. Fact is, if listeners cannot understand the words you are saying in American English, what good is having voice inflection and mastering the characteristics of optimal presentations?
How long does it take to form the habits of clear and accurate English? We break those habits into systematic and ordered skill sets and adhere to the average 70 days to form a habit for that speaking tool set. For more detail, http://www.cleartalkmastery.com/blog/2023/03/17/assessment-why-bother/
Later, we’ll get to the keys and secrets to how to speed up the process of acquiring accurate and clear American English speech along with other critical English speech skill sets for English speech communication proficiency. Hint—one is needs assessment and skills assessment. Another is distributed learning. Another is purposeful deliberate practice. And there really are 15 dimensions for successful acquisition of clear English speech.
Assessment– Why Bother?
Article 5 English Speech Assessment? Why Bother?
How important is assessment for successful acquisition of clear American English (AE) speaking? If we didn’t care about efficiency of learning, not important at all. Your money is worth a lot, but your time is worth even more. Important is determining nonnative-born individuals’ pronunciation for the 23 (some count 25) consonants and the 14 AE vowels (some count more), their knowledge of pronunciation rules and their current manner of talking. Easy to recognize is that in all spoken languages there are consonants and vowels which are pronounced the same as American English, others that are different. If the instructor (teacher, coach, tutor) and the student-learner know the errors for AE speech sounds and pronunciation rules, then instruction and learning can put disproportionate and more time to acquiring the AE pronunciation for errors and deficient skills with more efficiency and less time. “Thus, you know what to fix and what doesn’t need fixing.” Also, we also know what is the appropriate Level of Course for each person.
Critical is to assess or test all of the AE speech sounds, the most important pronunciation rules and the manner of talking Critical also is to assess or determine sources of the speech errors, including underlying physical differences, such as vocal strengt, range speech volume or loudness, and vocal flexibility.
We use the term “English speech communication and intelligibility.” Other terms used for decades include “Accent Reduction” or “Accent Modification” or English Pronunciation. What is “accent”? It is a pattern of speaking. Twenty-three languages of the roughly 7,000 languages in the world’s 196 countries are spoken by more than half of the world’s population, according to Ethnologue and The Intrepid Guide, 2022. Also there are a multitude of Englishes. The 2018 CIA World Factbook “Field Listing-Languages” reported that 58 sovereign states and 28 non-sovereign entities use English as their official language.
Fact is, many nonnative-born speakers of English or persons who have English as a Second Language (ESL), or English as an Other Language (ESOL) are using the pronunciation of consonants and vowels from their mother-tongue (the language they started speaking at about age one to four and beyond). Even if the individual is from a country where English is the official language, the pronunciation and other physiological characteristics of speech are not the same as American English speech.
For example, a prevalent and frequent difference in the pronunciation of consonants and vowels in other languages compared to American English is the duration of the speech sound. Specifically 70% of AE speech consonant and vowel sounds are double in duration of time (“slow”) compared to the quick or short in duration consonants and vowels. Other languages frequently speak the same consonants and vowels in a quicker or shortened duration compared to American English. For instance, prevalent is nonnative speakers pronouncing V, TH, M or N much more quickly than American English speech. Or the first language could make the speech sound more lengthy or slower. For example, in Spanish, the consonant sound CH is pronounced slowly, like the AE speech sound SH.
Not only that, the general stiffness or tension of the speech articulator muscles or the force of contraction (especially tongue, lips, jaw and muscles in the throat attached to the vocal folds) is a recognized feature of speech production (Gracco, 1994). Based on the articulatory acoustics (the “sound characteristics” of consonants and vowels) our observations and reports from nonnative speakers, American English has differences compared to other languages for speech articulator muscle tension and force of contractions in addition to critical differences for position of the tongue, lips, teeth and jaw. Muscular features can be inferred from an oral assessment of speech that tests all of the consonants and vowels in American English and uses sentences designed to control for coarticulation effects.
Task Dynamic Model of Speech Production focuses on the dynamics of human speech in that speech production, including clear English speech production, is a coordinated action (Kelso and Tuller, 1984, Saltzman et al, 2010, Parrell, B. et al 2018). Specifically, American English and clear American English speech are examples of manner or mode or style of speaking. The Central Nervous System (CNS) and especially the brain, dictates in a complex way the stiffness or tension of the muscles, the force of the muscles, the activation of motor neuron units and slow twitch and fast twitch muscle fibers, the duration of the speech sounds, and the coordination with the voicing at the vocal folds in the larynx of the throat. For more detail see Article 3 “Task Dynamic Model of Speech Production” – link here.
Initial diagnostic assessment tells the student-learner and the instructor/teacher/coach what to focus on for efficient acquisition of clear American English speech. We’ll come back to more on this later.
To circle back — 90 sovereign and non-sovereign entities have English as their official language, includjng India, Australia, Nigeria, Great Britain. British English matches most frequently American English pronunciation except for notably the American English short vowel A, short vowel O, and consonant R. For the other Englishes, there are multiple differences for duration of the consonants and vowels, the movement or the articulators (tongue, teeth, lips and jaw), and the volume or loudness of consonants especially at the ends of words or syllables. These differences put together are called “accented English.” Put simply, the more heavily the English is accented or the more differences in the speech production features compared to American English, the more difficult it is for native-born American persons and other internationally born speakers to understand the nonnative-born speaker. That’s called intelligibility (understandability).
Back to the topic of “Why bother with oral speech assessments? ” Vitally important are mid-course assessments to determine the change in pronunciation of all of the AE consonants and vowels, skill for pronunciation rules and patterns, and manner of talking. Is there an improvement in AE intelligibility (understandability)? Which AE speech sounds have improved and which sounds have not. Is the instruction and practice working for the individual like it works for most people? Thus at 3 weeks and 6 weeks of the 10 week instruction course, we do another assessment using an equivalent phonetically balanced test (10 different assessment tests). Thus, the instruction and home practice/direct practice and focus on deliberate practice in daily life (taking every opportunity to deliver clear American English) can be modified. Since on average it takes 70 days of practice everyday to change a habit (Frothingham, 2019) –in this case from accented English to clear American English speech– the end of the course assessment (10 weeks of coached instruction), is essential to determine intelligibility change. Assessment, especially after 10 weeks, is critical to measuring efficacy or success of the course and the methodology, and measuring speech changes which accompany specific changes in instruction.
As a sidebar, our initial diagnostic assessment also includes determining intelligibility of the student-learner when talking with background noise. That’s because all humans, especially those in professional roles that call for extended speaking such as teachers/professora, supervisors, ministry, tech people in collaboration, leaders, etc. need to be understood in large rooms or where there is background noise.
Sidebar number two- our initial diagnostic assessment includes a segment where we do a brief (about 25 minutes) training of the student-learner of the Six Clear Talk Strategies used by American English talkers when they want to be easily understood. Also the brief training includes critical enunciation instruction for clear American English, such as where to position or place the tongue for particular consonants and which AE speech sounds are quick and which have lengthier durations in time. Then we assess the student-learner on a different equivalent phonetically balanced test to determine how well they learn the strategies with added enunciation instruction. That information tells us a great deal about student-learners: How well do they learn from auditory instruction? How do they respond to the (dynamic) task of speak clearly using these strategies with the added enunciation training for American English. This gives us a leg-up or advantage to making the instruction for the coached course for each individual even more efficient.
And the initial diagnostic assessment answers the question of prognosis for the student-learner for the methodology of Clear Talk Mastery. In other words, with that brief training, did the student-learner measure better on the intelligibility test after the brief training compared to before the training? What speech sounds improved, and what are the likely sources or reasons for speech sounds and intelligibility not improving for American English after the training?
To circle back to the initial question, how important is assessment for successful acquisition of clear American English? Our answer — scientifically based English speech assessment is critical for several reasons. Most importantly, initial diagnostic assessment and mid-course assessments make for more efficient learning. Crucial for our instruction is also long-lasting learning – more about that later. Post course assessment examines the efficacy or success of the learning in our clear American English speech training program. It goes without saying that to determine success or efficacy requires comparison to skills and assessment before the instruction- the initial diagnostic assessment. The key question for post course assessment is “Does the Clear Talk Mastery program work or not?” and what are the successes and failures. That’s part of our Action Research—keep doing what works and change what doesn’t work (after you have tested it on a multiple people, not just one person!). Training and instruction improvement is one goal. Discovering what to change or keep for efficient and long-lasting American English, — that’s the other target for assessment. Can instruction and learning get better with using assessments and Action Research? We bet our life and work on that.

Pronunciation Tactics or Techniques To Speed Up Learning Clear English Speech
Why you should grow tongue muscle fibers using pronunciation tactics or techniques to most efficiently acquire and maintain clear American English speaking.
Understand this: By the time native-born children are 4 to 5 years old, they typically have a 1,500 to 2,200-word expressive vocabulary (Barnes, 2022). They pronounce most sounds correctly but may still have trouble with TH, R, S, L, V, CH, SH, and Z. At 8-years-old, native-born children have mastered all speech sounds as well as rate, pitch and volume and are capable of carrying on a conversation with an adult (Stewart, 2022). Notice that even for native-borns, the TH and L are not acquired accurately by 4 to 5 year old children who have been talking for 4 years!
Now for the topic at hand. Specific speaking tactics and exercises have speeded up learning and increased accuracy of English speech sounds for our student-learners. How do we know? Not just because we hear that, but because that is measured by assessments.
If you know the “why” you will understand the “how.”
For skeletal muscles (tongue muscles are skeletal), there are two kinds of muscle fibers, slow twitch muscle fibers and fast twitch muscle fibers. Scientific evidence indicates average percentage of slow twitch muscle fibers in human tongue is 54% — two-year-olds and adults (Sanders et al 2013).
Most English consonant and vowel sounds have an extended duration in time, double or more, compared to the quick consonants or vowels. Additionally, when the task is to speak clearly, English talkers do feature enhancement—they extend the duration of speech sounds (the slow consonants and lengthier duration vowels) and range of articulator movements (which is congruent with the task-dynamic model of speech production—Kelso & Tuller, 1984).
Getting the long duration English consonants (16 of 24 total consonant sounds) and vowels ( 9 of 14 vowel sounds) and mastering a different position of articulators for clear easy to perceive English speech sounds is challenging, to say the least, to the nonnative speaker. That two pronged skill is so critical, we teach it right away. Of course for some speech sounds, the positioning and speed of the articulators ( tongue, lips, teeth, jaw, vocal folds/chords) are the same as for other languages. It’s where English is different that makes the challenge.
For example TH both voiced and not voiced and L are high error speech sounds for nonnative speakers.
To produce clear, easy to understand TH or L speech sounds requires the tongue to be extended forward and for the duration of the speech sound to be extended for at least double or greater duration in time than a quick English sound such as the consonant sound D. With the eye, humans can’t see the slow twitch muscle fibers in the tongue. But it stands to reason that slow twitch muscle fibers are activated to push the tongue blade forward and to extend out or stretch out the tongue blade so the tip extends to the front of the mouth.
To systematize the new learning and to simplify (and because it works!), we teach the position of the tongue tip for the TH sounds and the L consonant sound to be the same. That is, push forward the tip of the tongue so it goes between the upper and lower front teeth or, better yet, to touch the lower lip.
Consonants TH and L are slow in speed and duration of the speech sound is lengthier than the quick consonants. The action of pushing the tongue tip all the way to the position of between upper and lower teeth or to touch the lower lip gives sensory feedback to the brain when the target has been reached. Critically, it takes time— milliseconds— for that tongue action which adds to the duration in time of the TH and L English speech sounds.
Thus you as speaker are taking advantage of biomechanical characteristics of movement of the tongue to extend the duration of the speech sound for the slow consonants TH and L. It stands to reason that your brain processes the task of pushing your tongue forward to the lower lip or between top and bottom front teeth and activates exactly the correct slow twitch muscle fibers. The central nervous system and the slow twitch muscle fibers must learn this pattern for easy to perceive North American English consonants TH and L. To make that tongue gesture and movement habitual takes much repeated practice.
Take home message for today, to acquire accurate American English pronunciation requires a tongue forward position for the consonants TH voiced and unvoiced and for L (and for the American short vowel A). The same is true for maintaining the accurate pronunciation for these speech sounds and maintaining the strength of those slow muscle fibers in the tongue needed for these speech sounds. The key for acquiring accuracy and maintaining speech sound accuracy is activating the slow muscle fibers to push forward and stretch forward the tongue—that stretching and lengthening the tongue blade not only grows the slow twitch muscle fibers but also biomechanically lengthens the duration of the speech sound when coordinated with voicing at the vocal folds.
Seeing and hearing is understanding.
Below is our speech tip 4 for WORLD— see the pronunciation for L. Hmm, picture says “PAPER.” Unfortunate that YouTube made a mistake for the picture– but click on this YouTube video for WORLD and L. You’ll be glad you did!
