Synchronous speech recognition system and method for mobile terminal and vehicle-mounted terminal

Abstract

The invention discloses a synchronous speech recognition system for a mobile terminal and a vehicle-mounted terminal. The speech recognition module converts the acquired pre-played text into audio stream data, and transmits the audio stream data to a recording and playing controller; the recording and playing controller will The received audio stream data is played through the audio; the recording playback controller obtains the playback progress of the current audio stream data according to the application programming interface, and judges whether the playback is completed through the current audio stream data playback progress; After completion, send the audio stream data playback completion notification signal to the speech recognition module. After receiving the audio stream data playback completion notification signal, the speech recognition module sends a recording start command to the microphone. After the microphone starts recording, the recorded voice information is transmitted to the speech recognition module. module for speech recognition. The data recorded by the tape recorder of the invention is very clean, which improves user experience.

Description

technical field [0001] The invention relates to the field of computer technology, in particular to a system and method for synchronous voice recognition of a mobile terminal and a vehicle-mounted terminal. Background technique [0002] With the continuous development of technology, the communication interaction between mobile terminals (mobile phones) and other computer terminals is very common. It can be connected through Bluetooth. When the mobile terminal uses the voice assistant, the sound will be played in the car stereo through Bluetooth, but the car Bluetooth will generally buffer the sound, which will cause the playback timeline to be delayed compared to the phone itself, so that the car terminal cannot Accurately know when to start the recording. If the recording is turned on too early, the last text played by Bluetooth will be recorded. If it is turned on too late, the user's voice will be missed, which will affect the customer's experience.
