Speech AI models
For transcription, call notes, voice assistants and spoken replies.
- 4 models
Speech models come in two directions. Speech-to-text turns calls, meetings and voice notes into text that other models can summarize and act on. Text-to-speech turns replies into natural spoken audio for phone assistants, audio content and accessibility.
For live voice assistants, speed matters as much as accuracy, so streaming support and response time are key checks.
