Draw and guess: The audio of a user in the room is pulled through this API for real-time recognition and then converted into text, which is called back to the customer’s business server for business logic judgment.
Audio audit: This API is closely related to business. It delivers the data streams to the speech recognition API for speech recognition and keyword-based filtering.
Real-time subtitles: The audio data in a room is recognized through this API in real time and converted into text, which is displayed at the frontend.
Architecture
The following figure shows the detailed process:
Application strengths
Real-time return: The audio data in a Tencent Real-Time Communication (TRTC) room is recognized and returned in real time, which is fast and efficient.
Simple process: TRTC and Automatic Speech Recognition (ASR) are deeply integrated, so that the data streams are fully pipelined without complex operations.
Flexible use: The data can be associated with the business logic in real time after it is returned to the business server.
Must-knows
In general, it takes a long time to process speech recognition because Async Execution is enabled during function deployment.
The recognition results are sent to the business server. WebSocket connections are not supported. Therefore, the recognition results cannot be sent to clients.
