Speech-to-text and voice intelligence APIs for developers
Choose pre-recorded transcription for files, a realtime API for live streams and voice agents, or a synchronous endpoint for short clips and dictation.
Layer summarization, sentiment, topic detection, PII redaction, content moderation and guardrails onto transcripts without building your own models.
AssemblyAI-TTS-1 is trained on real phone calls for natural, low-latency speech, targeted at IVR and voice-agent use cases.
Flagship models emphasise exact transcription, speaker labels and native code-switching across many languages, supported by published benchmarks.

AI transcription and meeting notes in 150+ languages
Connects to Google Calendar or Outlook and auto-joins Google Meet, Microsoft Teams and Zoom calls to capture live transcripts, summaries and action items.
Transcribes, subtitles and translates in over 150 languages in the same workspace, with automatic language detection and speaker diarization.
Add product names, people and acronyms once so every transcript and summary spells them the way you do.
Ask one question across all recorded meetings and get answers cited back to the minute they came from.
