  • Character Orchestration — Manage AI routers with create_router and chat_completions to build complex, context-aware conversational experiences.
  • Voice Library Management — List, update, and organize your workspace's voice assets and published models.
  • Speech-to-Text (STT) — Transcribe audio files directly into text for seamless agent processing.

Synthesize the text 'Welcome to the future of AI' using voice ID 'v-123' and the expressive delivery mode.

Processing synthesis with `synthesize_speech_sync`... The audio has been generated successfully using the `EXPRESSIVE` delivery mode. You can now play or download the result.

I'm using `design_voice` with your description. I've generated a preview for a 'Mysterious, deep-voiced wizard'. Would you like to hear the preview or publish this voice to your workspace?

You can use the `design_voice` tool. Simply provide a prompt like 'Warm, friendly male voice' and a preview text. The tool will generate voice options that you can later publish to your library.
