English: voicing contrast plus aspirationVoiced stops made with vibrating vocal folds from the start, voiceless stops aspirated word-initially but unaspirated after /s/.
Mandarin separates stops by aspiration alone; English relies mainly on voicing, with aspiration only as a secondary cue.

What you probably do

You likely rely on the presence or absence of a puff of air to tell English stops apart, since that's how Mandarin distinguishes p from pʰ, which can make it hard to produce or hear the voicing difference between English 'b' and 'p,' or 'd' and 't.'

How natives do it

Americans primarily use vocal fold vibration — true voicing — to separate pairs like 'big' and 'pig,' while aspiration is just a secondary cue that actually disappears after 's,' as in 'spin,' where the 'p' is unaspirated but still voiceless.

Why it matters

Relying only on aspiration can cause real word confusion, such as hearing or saying 'pig' for 'big,' and can make unaspirated sounds in clusters like 'spin' or 'skill' sound accidentally voiced to native ears.

How the mouth differs

Mandarin stops contrast by aspiration alone (p vs. pʰ), with no true voicing distinction, while English stops contrast primarily by voicing (b vs. p) with aspiration as a secondary cue that disappears after /s/; Mandarin speakers transfer their aspiration-based listening and speaking strategy, which can cause confusion with English voiced stops and with unaspirated voiceless stops in clusters like 'spin' or 'stop.'

Listen for the pattern

Because Mandarin has no voiced stop category, English 'b,' 'd,' and 'g' can sound insufficiently distinct from 'p,' 't,' and 'k' to Mandarin speakers, and unaspirated /p,t,k/ after /s/ can be misheard or mispronounced as voiced sounds.

Try these sentences

  • That's a big pig.
    'big' voiced [b], 'pig' voiceless aspirated [pʰ]
  • Please spin the top.
    'spin' has unaspirated [p] after /s/, unlike word-initial 'pin'

Practise it

Overshoot the Puff, Then Shrink It

sourced
exaggeration 5 min ★☆☆ recorder
  1. Say 'Peter' with a huge, almost 'p-h-eter' puff of air after the first p.
  2. Repeat this exaggerated version three times, feeling the strong breath release.
  3. Say 'Peter' again with about half that amount of air.
  4. Say it once more at a natural, comfortable level, keeping a clear but shorter puff.
  5. Repeat the same three steps with 'tea' and 'key'.
  6. Record your final natural versions and check them against a model recording.

Success check: Your natural-level recording still has a clearly audible puff of air after p, t, and k, just smaller than your first exaggerated attempt.

A strong, almost 'h'-like puff of air clearly audible after the consonant release.
ExaggeratedA strong, almost 'h'-like puff of air clearly audible after the consonant release.
A shorter but still clearly present puff of air after the consonant release.
NaturalA shorter but still clearly present puff of air after the consonant release.
First blow out a big 'h'-like puff after the stop, then shrink it to a natural but still audible burst.

Why this works. Over-aspirating stops into an almost audible 'h' after the release lets the learner isolate and feel the glottal delay that produces aspiration, before scaling the airflow back down to a natural but still clearly aspirated level; this overshoot-then-reduce strategy mirrors training protocols where exaggerated acoustic contrasts sharpen perceptual categories prior to natural-level production.

Drill the Aspirated Onset

sourced
drill sentence 6 min ★★☆ recorder
  1. Say 'Peter poured the tea into two cups' slowly, pausing right after each p and t to add a small puff of air.
  2. Speed up gradually while keeping that puff audible on each stressed p/t.
  3. Say 'Kate's cat kept the key' the same way, adding a puff after each stressed k.
  4. Record both sentences at a natural conversational pace.
  5. Listen back and underline any stop that sounds like it's missing its puff of air.
  6. Redo just the underlined words with extra breath support.

Success check: You can clearly hear a short burst of air after every stressed p, t, and k in both sentences when played back.

A small burst of air drawn right after each marked consonant below.
Aspirated targetA small burst of air drawn right after each marked consonant below.
Add a clear puff of air right after each marked p, t, or k before the vowel starts.

Why this works. A carrier sentence packed with multiple stressed p/t/k onsets lets the learner practice the aspiration gesture repeatedly within one breath group, building a motor habit of delaying voicing onset specifically in stressed-syllable-initial position while contrasting it with the unaspirated post-s environment.

  • Targeted Pronunciation Instruction in Multilingual Classrooms... — 2025
    • Vowel contrast accuracy improved significantly from 62.5% to 78.3% in the targeted group, compared to only a 2.3% gain in the control group.
    • Stress accuracy rose from 60.8% to 76.4% for learners receiving targeted instruction, with large effect sizes (d=1.48 for vowels, d=0.92 for stress).
    • Qualitative data revealed that learners adopted durable strategies such as minimal pair drills and shadowing, leading to fewer real-world misunderstandings.

Shadow the Puff of Air

consensus
shadowing 7 min ★★☆ recorder
  1. Listen to 'Peter poured the tea into two cups' once without speaking.
  2. Hold a strip of paper near your mouth and play the recording again, starting to shadow it a beat behind.
  3. Watch the paper move on 'Peter', 'poured', 'tea', and 'two', matching the model's timing.
  4. Record yourself shadowing the full sentence three times.
  5. Repeat the process with 'Kate's cat kept the key.'
  6. Compare your recording to the model and note any stops that lack a visible or audible puff.

Success check: The paper strip visibly flutters right after you release p, t, or k at the start of 'Peter', 'tea', 'two', 'Kate's', 'cat', 'kept', and 'key', timed with the recording.

ModelA visible puff of breath released right after the lips or tongue open for p, t, or k.Looks almost the same as the picture.
Matching puff of breath timed to the model's release.
Your shadowMatching puff of breath timed to the model's release.
Shadow closely enough that your puff of air after p, t, k lands at the same moment as the model's.

Why this works. Shadowing the model's stressed-syllable-initial stops in real time trains the release-to-voicing timing (voice onset time) needed for aspiration, since matching the model's exact release-to-voicing gap is only possible if the learner delays glottal closure the way English speakers do.
