Problems solved by technology

[0003] However, the current problem is that since the total average data transmission bandwidth of the uplink and downlink is fixed, if the quality of downlink audio playback is guaranteed (that is, the downlink transmission rate is increased), the delay of voice interaction from wake-up to recognition will become longer. More than 2 seconds will affect the user experience; if the response speed of the voice interaction from wake-up to recognition is guaranteed so that the

Abstract

The invention discloses a Bluetooth speaker and a control method and system thereof and a storage medium. The control method includes the steps that first protocol connection and second protocol connection between the Bluetooth speaker and a mobile terminal are established; voice data collected by the Bluetooth speaker are acquired, and the collected voice data is compressed according to a pre-negotiated compression multiple; the compressed voice data are transmitted to the mobile terminal by using the first protocol connection, the mobile terminal decompresses the received voice data and sends the decompressed voice data to a server for voice recognition to obtain identified audio data; and the audio data returned by the mobile terminal is received based on the second protocol connection,and an audio output module in the Bluetooth speaker is controlled to play the audio data. The control method adopts a Bluetooth two-way high-speed transmission protocol to realize the two-way high-speed transmission function of the voice data between the Bluetooth speaker and the mobile terminal, and can greatly enhance the far-field voice interaction experience of the Bluetooth speaker.

Description

technical field [0001] The invention relates to the field of communication technology, in particular to a bluetooth speaker, its control method, system and computer-readable storage medium. Background technique [0002] In related technologies, existing Bluetooth speakers usually use standard Bluetooth 4.2 and BLE (Bluetooh Low Energy, Bluetooth low energy) technology for two-way communication. In the normal playback mode, most of them use the A2DP (Advanced Audio Distribution Profile, Bluetooth Audio Transmission Model Protocol) protocol for audio playback. At this time, the uplink can only use BLE to transmit data. In order to ensure the stability of Bluetooth playback, the BLE transmission rate is usually limited to 16kbps (where kbps is also called the bit rate, which refers to the transmission rate of digital signals). In the call state, most of them use the HFP (Hands-freeProfile, Bluetooth hands-free application protocol) protocol for communication, and the uplink an...
