What is AI Chat
AI Chat is a real-time voice interaction service provided by the Tange platform for IoT devices. Built on TiRTC transport technology, it enables devices to complete the full loop of Automatic Speech Recognition (ASR), Large Language Model reasoning (LLM), and Text-to-Speech synthesis (TTS) over a single low-latency connection, while also transmitting captions, interruptions, device capability events, and other control messages on the same connection.
In the documentation and console, you may encounter different names such as "AI Chat", "AI Talk", or the Chinese term "AI 对讲". They all refer to the same product.
Product Components
| Component | Description |
|---|---|
| TiRTC Transport Layer | Provides a low-latency audio and command channel between the device and the platform. The device integrates via the TiRTC SDK (C language). |
| AI Chat Platform | Runs cloud-based ASR, LLM reasoning, TTS synthesis, and event dispatch, and manages the session lifecycle. |
| AI Talk Console | A visual interface for creating AI agent roles, managing knowledge bases, and configuring device-side/cloud-side plugins. |
| Server API | The application server calls TGV1-HMAC-SHA256 signed APIs to request connection credentials for devices. |
Use Cases
- AI toys and companion devices: voice conversation, storytelling, interactive play.
- Smart speakers and voice assistants: information queries, schedule management, smart home control.
- Smart cameras and doorbells: visitor voice interaction, remote intercom.
- Robots and industrial terminals: voice command control, status announcements, anomaly Q&A.
- Wearable devices: low-power voice interaction.
Key Advantages
- End-to-end low latency: Connections are established via the TiRTC WHIP protocol, enabling low full-chain latency from speech recognition to reply delivery.
- Single-connection full duplex: Audio uplink/downlink, captions, events, and session control all share one TiRTC connection, simplifying device-side integration.
- Flexible agent configuration: Visually configure role prompts, voice, knowledge bases, and device/cloud plugins through the console—no firmware changes required.
- Lightweight device side: The device only needs to integrate the TiRTC C SDK; ASR, LLM, and TTS all run on the platform side, ideal for resource-constrained MCUs and embedded devices.
- Open event protocol: Supports custom business events and device capability calls for bidirectional device-platform collaboration.
