Start by recording yourself reading a short familiar paragraph. A recording lets you test pronunciation against what you hear, rather than trusting a vague feeling. Replay it and note one word you want a listener to hear more clearly.
A repeatable practice loop
Record yourself saying the same five-sentence paragraph three times. Between takes, replay the previous one and pick a single word to focus on for the next take. Name that word out loud before recording, for example water or difficult, so your listening has one clear target. Do not decide in advance how you will change it. Simply listen back and notice what you hear on that word each time.
Score each take on a simple 1 to 5 rubric across four features: individual sounds, word stress, sentence rhythm, and overall intelligibility. Keeping the same rubric each time makes takes comparable.
Read the paragraph aloud once for a real listener, then ask one concrete question: Which word was hardest to follow? A listener answer often points to intelligibility, not the sound you were polishing.
If a tool gives you a score, compare it against your own rubric before accepting it. In at least one study, an AI tool scored higher than human raters on every feature, so treat any tool number as one opinion, not a verdict.
The exercise in full
Here is the whole exercise worked through with a short paragraph, for example a five-sentence passage from a graded reader you already know. Record it once before changing anything, so your first take shows your natural habits rather than a rehearsed version.
First take: read the paragraph at normal speed and keep the recording. This take is your baseline, showing the habits you already have.
Second take: choose one word from the paragraph, for example the stressed word in its key phrase. Record again while attending only to that word and its stress, and keep this recording too.
Third take: choose a different word, or the same word with attention on a different feature such as its final consonant. Record a third time with that single focus, and keep the recording.
Because each take changes only one point of attention, you can replay the three recordings and compare them directly. Any difference you hear between takes points to the word and feature you were attending to, which makes the comparison meaningful.
Now replay all three takes and score each on a 1 to 5 scale for four features: individual sounds, word stress, sentence rhythm, and overall intelligibility. Write the numbers down. For example, a take might earn 3 for sounds, 4 for stress, 3 for rhythm, and 4 for intelligibility.
Next, read the paragraph aloud once for a real listener and ask which word was hardest to follow. If they point to a word you polished for its sound, that tells you intelligibility and your own scoring can disagree.
A method is reliable for you when it uses the same criteria every take, scores the words you actually said, and agrees with your own rubric or a listener. Omitted or skipped words that a tool never scored are one reported flaw, and that came from rater interviews rather than direct measurement.
If a tool offers a score, check it against your rubric before accepting it. Is it uniformly higher than your numbers? In at least one study, AI scores ran higher than human raters on every feature, so treat a tool number as one opinion, not a verdict.
Judging what you hear
A usable self-check is comparing your recording against the transcript, word by word. Play the audio once and put a check mark beside every word you can hear clearly. Words you cannot hear on your own recording are the ones a listener will most likely miss too.
Then check one feature at a time, with word stress as today's feature. Pick a longer word straight from your own paragraph. Replay that word and listen only for which syllable comes through stronger and clearer, because that syllable carries the stress. If the choice is not obvious, hum the word first; the syllable your voice pushes hardest on is the stressed one. You do not need perfect sounds today; a single feature check gives you a result you can actually judge.
One honest-result trap is the tool score. If a tool score sits well above your own rubric numbers, trust your recording and your listener first; reported AI scores can run higher than human raters. On the other hand, if you can hear every word clearly, that is a good result, so move to a harder paragraph.
For the next adjustment, apply the loop above, then choose one feature to score on its own in your next recording.
