OEM SDK
Named phoneme scores, on the device
Brainiall Pronounce SDK scores pronunciation for Portuguese speakers (and English) on the device — 17 MB, CPU, audio never leaves the phone — or over API. One-week pilot. Price per device, per student, or per request. Built for language platforms, schools, and publishers.
Public benchmark: 5,000 utterances, 5 raters, sentence PCC 0.71.
What this SDK ships that a cloud score does not
Phoneme names in Portuguese
Feedback names the phoneme in pt-BR (and in English). The student sees which sound missed, not a silent number.
Score on the device
17 MB on CPU. Median on-device latency under 300 ms. Audio does not leave the phone.
Price per device, student, or request
Contract like a language platform: US$1.00 per device per year up to 5,000 devices, US$3.00 per student per year, or US$0.006 per request.
How it works
Install or call
Drop the on-device SDK into the app, or send audio to the API. Same scoring contract either way.
Speak against a prompt
The product sends the recording and the expected phrase. Nothing else is required to get a score.
Return named phoneme feedback
Sentence score plus the phonemes that missed, named so a Portuguese speaker can act on them.

Where audio goes
On the device
Scoring runs on the phone or tablet. Audio does not leave the device.
API
Audio sent to the API is scored and discarded. Retention is 0 days.
Questions
Who is the Pronounce SDK for?
Language platforms, schools, and publishers that need pronunciation scoring with named phoneme feedback for Portuguese speakers, and for English. OEM install, not a consumer app.
Does audio leave the device?
Not on the on-device SDK. The 17 MB package scores on CPU and keeps the recording on the phone. The API path discards audio the same day — retention is 0 days.
How is it priced?
Three meters: US$1.00 per device per year up to 5,000 devices, US$3.00 per student per year, or US$0.006 per API request. Pick the one that matches how you already bill.
What does the public benchmark show?
5,000 utterances, 5 raters. Sentence PCC 0.71 on the public set. The numbers and the protocol are in the pilot kit.
How long is a pilot?
One week. The kit has the install steps, the scoring contract, and the list prices. Start from the form — there is no monthly cloud floor to open a trial.
