Phoneme-Level Speech API

Targeted phoneme practice with AI coaching

Sound Trainer turns a target phoneme into a short speech motor chaining plan. Learners record each attempt, receive phoneme-level analysis, and get concise corrective cues that adapt to recent practice history.

How it works

  • Pick a target sound: choose the phoneme or sound the learner wants to practice.
  • Get a motor plan: the agent builds a step-by-step sequence from isolation to short phrases.
  • Record attempts: each learner attempt is analyzed with top-k phoneme evidence.
  • Receive corrective feedback: the next cue uses recent attempts to decide what to fix now.
