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.
Voice AI that understands how people really sound
Voice analysis covering phonatory, articulatory and prosodic dimensions, forming the basis for expression and biomarker models.
Detects and classifies emotional states from tone of voice to power empathic and responsive interfaces.
Deploy the models as an SDK, a web API or a plugin, so the technology can be embedded into existing products.
Adds expressivity understanding to VR, AR, MR and game-engine projects for more natural avatars and agents.
