Test Suite APIs, Enhanced Call Transfers, Voice Model Enhancements

1. Introducing Test Suite Management APIs: You can now test your assistant conversations before deploying them by creating end-to-end tests, adding test cases, and running and reviewing test suites. You can configure these tests through the Test Suites dashboard page and Test Suite APIs, and learn more in the docs.

2. Enhanced Call Transfers with TwiML Control: You can now use twiml (Twilio Markup Language) in Assistant.model.tools[type="transferCall"].destinations[].transferPlan[mode="warm-transfer-twiml"] to execute TwiML instructions before connecting the call, allowing for pre-transfer announcements or data collection with Twilio.

3. New Voice Models and Experimental Controls:

   • mistv2 Rime AI Voice: You can now use the mistv2 model in Assistant.voice[provider="rime-ai"].model[model="mistv2"].
   • OpenAI Models: You can now use chatgpt-4o-latest model in Assistant.model[provider="openai"].model[model="chatgpt-4o-latest"].

4. Experimental Controls for Cartesia Voices: You can now specify your Cartesia voice speed (string) and emotional range (array) with Assistant.voice[provider="cartesia"].experimentalControls. For example:

{
    "speed": "fast",
    "emotion": [
        "anger:lowest",
        "curiosity:high"
    ]
