API Description
The Real-Time ASR API complies with the WebSocket protocol, and provides three modes: Streaming, Continuous, and Single-sentence.
The handshake request wss-URI of each mode differs, but the formats of requests and responses are the same.
Developers can use a WebSocket software package or library interface in the Java, Python, or C++ language to handshake with the Real-Time ASR engine, send the speech data, and obtain the recognition result. After the recognition work is done, close the WebSocket connection.
- For details about how to obtain the WebSocket handshake request wss-URI, see WebSocket Handshake Requests.
- For details about the format of a Real-Time ASR request, see Real-Time ASR Requests.
- For details about the format of a Real-Time ASR response, see Real-Time ASR Responses.
When a client uses the WebSocket protocol to access the RASR APIs, the connection can last 5 hours at most. If the WebSocket connection lasts more than 5 hours, the server automatically closes it.
