Most engineers know AssemblyAI for speech-to-text.

The rest of the stack is already behind the same key.

Transcribe a recording, then redact PII, label speakers, detect entities, and summarize, all native.

The features you were about to go build already exist.

AssemblyAI Full Voice AI stack behind one API key — transcription, speaker ID and sentiment, an LLM gateway, and PII redaction, all native to the same platform. For example, their Voice Agent API ships with turn detection and interruption handling built in, so you can build a working voice agent without wiring that logic yourself.
