Brainiall for EdTech
Score pronunciation above human raters. Ship language apps that adults pay for.
Phone PCC 0.682 vs human 0.555 — the only commercial pronunciation API above human inter-annotator agreement. Add native-quality fluency feedback to your courses without hiring a speech lab.
What we hear from EdTech teams
Off-the-shelf STT can't tell a thick accent from a real mispronunciation — your learners get false negatives.
Building your own scoring system means hiring linguists, collecting calibration data, and re-running every quarter.
Hyperscaler APIs charge per minute — viable for occasional use, not for daily speaking drills.
How Brainiall solves them
Per-phoneme + per-word + per-sentence scoring
Returns aligned per-phoneme confidence + word & sentence-level Pearson scores. Color-code in your UI. Drives streaks and corrective drills without false alarms.
Volume-priced for daily drills
$0.10 per hour of audio. Compare to Azure Speech Pronunciation at $1.00/hour. 90% discount on the assessment SKU — the unit-econ that makes a daily-speaking app actually work.
OpenAI-compatible drop-in
Same Bearer key as the other 13 specialty APIs. Switch on STT, TTS, translation, sentiment — all from one SDK. Cut your audio infra dependencies from 5 vendors to 1.
