Abstract

The invention relates to the field of personal mobility technology and vehicle-mounted Bluetooth technology and discloses a Bluetooth voice control method and device and an intelligent terminal. The method comprises the steps of conducting Bluetooth matching and connection with a peripheral, sending a request signal to the peripheral, attempting connection with an RFCOMM channel set by the peripheral, receiving an RFCOMM channel establishment confirmation signal returned by the peripheral, establishing a Socket port based on an RFCOMM, receiving a VTCP data packet transmitted from the peripheral through the Socket port, recognizing a voice instruction in the data packet and converting the voice instruction into a specific control instruction for operation of the intelligent terminal. According to the Bluetooth voice control method, device and intelligent terminal, a VTCP is adopted to transmit 16-KHz voice signals through the RFCOMM channel, so that the voice recognition rate is effectively increased; furthermore, efficient and accurate voice control over the intelligent terminal is achieved, and safety and convenience in the process of controlling the intelligent terminal by a user are guaranteed to the maximum extent.

Description

technical field

[0001] The invention belongs to the technical field of personal mobility and vehicle-mounted Bluetooth, and in particular relates to a Bluetooth voice control method, device and intelligent terminal. Background technique

[0002] With the increasing popularity of smart phones, more and more mobile Internet applications can allow people to obtain more convenience and enjoyment while driving. However, operating a mobile phone while driving a car is a behavior that endangers driving safety, so current drivers mainly rely on Bluetooth to wirelessly use some basic functions of the mobile phone when driving. The current car Bluetooth devices are mainly hands-free phones, Bluetooth headsets, etc., and their working principle is to connect to the mobile phone through the standard Bluetooth protocol, and wirelessly control the mobile phone to answer calls and play music. However, limited by equipment and protocols, the existing Bluetooth method cannot control other f...
