AssemblyAI

Speech-to-text and voice intelligence APIs for developers

Async, realtime and sync speech-to-text

Choose pre-recorded transcription for files, a realtime API for live streams and voice agents, or a synchronous endpoint for short clips and dictation.

Audio intelligence and Speech Understanding

Layer summarization, sentiment, topic detection, PII redaction, content moderation and guardrails onto transcripts without building your own models.

Text-to-speech for voice agents

AssemblyAI-TTS-1 is trained on real phone calls for natural, low-latency speech, targeted at IVR and voice-agent use cases.

High accuracy with diarization

Flagship models emphasise exact transcription, speaker labels and native code-switching across many languages, supported by published benchmarks.
