PT speakers
How do you see pronunciation errors typical of Portuguese speakers?
The page has no secret list of “Brazilian errors”. it aligns the English phrase and shows the phone Portuguese speakers often trip on TH, on ship/sheep and on R — that is a contrast description, not a statistic Measure it on the tape: 0–39 and 40–59.
How to do it in three steps
Build phrases that hold the contrast you want to see: think/sink, ship/sheep, right/light. The same phrase, several days. Phone PCC 0.682 against 0.555 at /aprender/pcc.
- Type the contrast phrase. Record up to 60 s, 8 MB, 15–30 cm, SNR above 15 dB.
- Open the word below 50. Read the phone in IPA. Do not ask the page for a “Brazilian error” badge: ask for the phone.
- Train only that phone in the same phrase. Sentence fluency above 70 does not excuse a phone in 0–39. /aprender/quatro-niveis.
What to expect: formats, size and time
8 MB, 60 s, 16 kHz. No nationality ranking. No percentage of “how many Brazilians miss TH”. No accent list.
Confidence under 0.5 discards the take. A noisy room pretends to be a phone error. /aprender/quando-desconfiar-do-score.

One contrast phrase today: free page. A class: API.
The free page exists so you can try the flow with a real file, see the result, and only then decide whether the API belongs in the operations pipe. Nothing is published, sent or charged from here: the click goes to the tool, and the account lives on products and pricing when volume no longer fits in the tab. This screen is the rehearsal; the API is the lot, the key and the account quota.
Frequently asked questions
Does the tool detect a Brazilian accent?
No. It aligns phones of the English phrase. Accent is conversation; the phone is the tape.
Do you publish which errors are most common?
No. There is no ranking on this page. There are bands 0–39 to 80–100 in the guide.
Does TH show up as a phoneme on the tape?
If the reference had the phone and alignment caught it, yes. Type the word that holds the contrast.
Can I record in Portuguese?
The tool scores the reference phrase you typed. For English, type English.
