Focus

Speech AI · SaaS

AccentHelper scores speech relative to the speaker's goal instead of grading everyone against a generic native-likeness number. Five goal types (accent reduction, confidence, code-switching, public speaking, acting) route to different scoring pipelines: Azure pronunciation assessment plus audio-capable LLMs where phoneme detail matters, audio-LLM coaching where it does not.

Highlights

▹Goal-aware scoring across five speaker-goal types
▹Azure Pronunciation Assessment plus multimodal LLM feedback on raw audio
▹Adaptive practice sessions with phoneme-level progress tracking
▹348 automated tests across the scoring and session pipeline
