Solutions / Speech AI
Speech AI
Japanese ASR and TTS are sensitive to dialect, pitch accent, mora timing, and the gap between read and spontaneous speech.
What this use case needs
Dialect and demographic coverage
Standard Tokyo speech is well served. Regional, age-diverse and non-studio speech is where error rates rise.
Conversation and call audio
Spontaneous, overlapping, keigo-heavy speech with proper consent and de-identification.
Studio voice for synthesis
Consent-licensed voice talent in defined styles, with clear commercial synthesis rights.
Common pitfalls
- Voice rights that do not cover synthesis
- Read-speech-only corpora
- Missing consent chain for call recordings
