What it can do
- Core workflow
Rime supplies speech synthesis: Coda for expressive speech and Mist v3 for a latency-oriented voice component, with voice controls, pronunciation dictionaries, streaming and timestamps. Developers supply text, application logic and surrounding STT/LLM/transport. It is not a 10-million-token general AI, RAG or multimodal orchestration platform.[1], [2], [3], [4], [5], [6]
- Connections and scope
HTTP streaming/WebSocket APIs, LiveKit and Pipecat examples and first-party MCP at mcp.rime.ai are documented. MCP supports voice lookup, dictionaries, normalization, code examples and sample synthesis; production streaming remains an API workflow. Application orchestration and phone transport are separate.[1], [2], [3], [4], [5], [6]
