Test
How do you test your English pronunciation now?
The test is a take, not an exam. you type the phrase, record, and read overallScore with the per-word tape Phone PCC 0.682 against 0.555 lives at /aprender/pcc Without a reference phrase, there is no test: there is a guess.
How to do it in three steps
Say the phrase you actually use: an introduction, a request, a meeting question. A textbook sentence you never say measures something else.
- Type the phrase. Record between 0.5 s and 60 s, file up to 8 MB. Mic at 15–30 cm. SNR above 15 dB; 20 dB is the cleaner room in the guide.
- Read overallScore. If confidence is under 0.5, throw the take out: the engine is saying the audio and the phrase do not match. Guide: /aprender/quando-desconfiar-do-score.
- Open the words in 0–39 and 40–59. Train only those. A single test is not a curve; it is a point. Repeat the same phrase tomorrow.

Frequently asked questions
Does the test count as a certificate?
No. It is a take with overallScore and a tape. A certificate is another contract, off this page.
Can I record on a phone?
If the browser records or sends a file up to 8 MB and 60 s, yes. Watch wind and a speaker in the same pocket.
What if I say a different phrase?
Forced alignment does not swap the reference. Confidence drops. Type what you said, or say what you typed.
