About the Speech-to-Text Practice
If a speech recogniser understands you, a listener probably will too. This tool gives you a target sentence, listens to you say it, and compares the recognised text with the original, word by word: green for matched, amber for close, red for missed, and extra words you added.
The accuracy figure is the share of target words recognised exactly. It is a useful signal for clarity, but it is not a pronunciation score: recognisers also make mistakes, so repeat tricky lines a couple of times. If your browser does not support speech recognition you'll see a clear message and can still listen to the sentence and record yourself.
Using a recogniser as a mirror is a practical, low-cost way to notice unclear words. If a word is repeatedly marked missed, ask yourself whether the vowel, the stress or the final consonant is unclear, then isolate it with the Minimal Pair Trainer or the Pronunciation Trainer. Remember that very short words are often dropped in fast, natural speech, and that is normal.
How to use it
- 1Choose a level and a sentence (or type your own).
- 2Press Listen to hear it, then Speak and read it aloud.
- 3Press Stop. See which words matched, which were close and which were missed.
- 4Try again on the red words until the sentence turns green.
Practice tips
- Speak at a natural pace; very slow speech can confuse recognisers.
- A quiet room matters more than a fancy microphone.
- If one word keeps failing, repeat it alone then in the sentence.
- Use English (US) or (UK) to match the accent you practise.
What it measures, and what it doesn’t
Accuracy = target words recognised exactly ÷ target words. Recognition is done by your browser (in Chrome and Edge via an online service). It judges text, not tone or accent, so it can be wrong.
What your browser needs: A browser with the Web Speech API (Chrome, Edge, Safari); A microphone.

Speech-to-Text Practice FAQ
Is this a real pronunciation score?
No. It reports which words a speech recogniser transcribed correctly. That is useful feedback on clarity, but it is not an acoustic assessment of your accent.
Why does it say my browser isn't supported?
Firefox does not provide the Web Speech recognition API. Use Chrome, Edge or Safari, or use the other tools here which work without it.
Is my voice stored?
We don't store or upload it. In Chrome and Edge your browser may send audio to its own speech service to transcribe it, as described in that browser's privacy policy.
