How to Use AI Pronunciation Evaluation: Reading the Scores That Actually Matter
You want to improve your English pronunciation but don’t want to record yourself for a human teacher who will say “good!” without telling you what was actually off. SpeakSmart’s Pronunciation module gives you phoneme-level feedback every time you record. Here’s how to use it and how to read the scores.
What Powers It
Microsoft’s Azure Speech SDK. Not a general-purpose language model — a specialized speech recognition system that scores each individual sound. When the score says your /θ/ in “think” was 62% accurate, it’s measuring exactly what it says it’s measuring.
Asking a human teacher to listen to the same word twenty times gets awkward fast. The AI doesn’t care. You can record the same sentence fifty times if that’s what fixing it takes.
The Two Modes
Read Aloud
You read a text out loud. Pick a preset (short sentences, longer passages, news-style paragraphs) or paste your own. Use this when you want to drill specific sounds or sentence patterns.
Free Speech
You pick a topic and speak about it in your own words. Self-introduction, recent events, favorite food. Harder than read-aloud because you’re producing language while also focusing on sound, but closer to actual conversation.
Step-by-Step
1. Open Pronunciation, choose your mode
After signing in, find Pronunciation in the navigation. Two tabs at the top: Read Aloud and Free Speech.
2. Pick or paste content
For read-aloud mode, start with a short preset — 10 to 20 words. Long passages are harder to score consistently and harder to fix when something goes wrong.
3. Record
Hit the mic button, speak, hit stop. The browser will ask for mic permission the first time; grant it. You can also upload an audio file if you’d rather record outside the browser.
4. Submit for evaluation
Ten to twenty seconds of processing. The result comes back as scores plus a per-phoneme breakdown.
Reading the Scores
Accuracy
How close each phoneme was to a native reference. 0–100. Above 80 is generally intelligible. 60–80 means the listener can mostly understand but might notice something. Below 60 means specific phonemes are pulling your overall score down — that’s where to focus.
Fluency
How natural the rhythm was — pauses, connections, unnatural breaks. If you tend to read word-by-word with even spacing, this score will be low. If you group words into natural phrases, it climbs.
Completeness
Did you actually pronounce all the words in the target text? Skipping or mumbling words drops this number. Mostly relevant in read-aloud mode.
Prosody
Stress, rhythm, intonation. This is the hardest number for Japanese, Korean, and Chinese learners to move, and the one that makes the biggest difference to sounding natural. Worth specifically targeting once your accuracy is consistently above 75.
The phoneme-level detail
Below the scores, you see exactly which sounds were weak. Specific IPA symbols, the word and position they came from. This is where the actual learning instruction lives. “Your /θ/ is consistently weak; your /v/ collapses to /b/ in word-initial position; your final consonants are being dropped.” Read this section every time.
How to Turn Scores into Improvement
Watch the trend, not the single score
A score of 72 on Monday and 78 on Wednesday doesn’t mean you got dramatically better in two days — there’s noise per session. What does mean something: average score on similar material rising over weeks. The Learning Log tracks this for you.
Pick one or two phonemes per fortnight
Don’t try to fix everything at once. Look at the per-phoneme breakdown, identify your worst one or two sounds, and drill those specifically for two weeks. Minimal pair drills work well here — “right/light,” “think/sink,” “very/berry.” After two weeks, those phonemes will have shifted measurably. Move to the next ones.
Repeat the same sentence 5–10 times
New sentences every session feel like progress but don’t produce it. Same short sentence, recorded five to ten times, with conscious adjustments based on the previous attempt’s scores — that’s where motor memory locks in.
Common Snags
Scores are surprisingly low
First thing to check: environment. Background noise, distance from the mic, an air conditioner you forgot was on. A quiet room with the mic 15–20 cm from your mouth changes results substantially.
Read-aloud falling apart on longer passages
Read silently once before recording. Get the meaning and the structure into your head first. Then read aloud. Cold-reading a paragraph always scores worse than a second pass.
Feels like no progress after weeks
Pronunciation improves slowly. A week is too short to see anything. Two to four weeks is where it shows up. Compare your average score and which phonemes are weak now versus a month ago — there will be movement, even if it doesn’t feel like it day-to-day.
The Free Plan
Pronunciation evaluations are limited to 2 per day on the free plan, no credit card. That’s enough to build a real habit. The pronunciation-only paid plan starts at a few hundred yen per month if you want unlimited.
Closing
Pronunciation work has a bad reputation because it usually requires expensive feedback and feels slow. Phoneme-level AI scoring fixes the first problem entirely and makes the second one bearable, because you can see the slow change in numbers. Two daily recordings, focused on a specific weak phoneme for two weeks, will move things in a way you can feel by week three.
