Voice Agent Platforms
Build-your-own voice agents: orchestration, turn-taking, interruption handling and telephony glue. This is where the advertised per-minute rate diverges furthest from the invoice.
The thing buyers get wrong here
Bring-your-own-key pricing means the headline rate is orchestration only. Speech-to-text, the model and text-to-speech land on separate bills and roughly triple the number.
