About AssemblyAI
AssemblyAI stopped selling transcription and started selling the whole voice agent.
AssemblyAI shipped a Voice Agent API that delivers speech understanding, LLM reasoning, and voice generation over a single WebSocket at one $4.50/hr rate, built on its own models. Around it, streaming speaker diarization got an accuracy upgrade with per-word labels across US and EU regions, the LLM Gateway gained a json-repair post-processing step, and PII redaction can now return redacted and unredacted transcripts in one request.
