+ The pipeline is explicit, so interruption handling and turn-taking are yours to tune.
− A library, not a dashboard: no call logs or flow editor unless you build them.
+ WebRTC underneath means in-app and in-browser voice, not only phone calls.
− You run the media plane or pay for theirs - the framework alone is not a product.
+ Among the fastest real-time transcription APIs available, with diarization and keyword boosting built in.
− Developer-only; there is no end-user app, and accuracy on heavily accented speech trails Whisper-class models.
+ Latency low enough for a voice agent that can be interrupted.
− Fewer polished preset voices than ElevenLabs, and it is API-first.
+ The voice is the best part of the stack and it is included rather than bolted on.
− Minutes are priced as voice, not as orchestration - heavy call volume gets expensive.
