Method, device and system for voice interaction

1. A method for voice interaction, comprising:

determining that an external device adopts Universal Serial Bus (USB)2.0 standard for transmission and the external device supports a voice function; and

conducting voice interaction with the external device by adopting customized MIC lines and SPK lines in a micro USB3.0-B female connector interface;

wherein conducting the voice interaction with the external device by adopting the MIC lines and the SPK lines comprises: conducting the voice interaction with the external device by adopting MIC lines and SPK lines via a USB shielding line which converts a USB3.0-A interface into a micro USB3.0-B male connector interface, wherein after generating a to-be-sent analogue voice signal through a processing of digital-to-analogue conversion, data voice information to be sent to the external device is sent to the external device via the USB shielding line, and/or, after a processing of analogue-to-digital conversion, an analogue voice signal received from the external device via the USB shielding line generates a to-be-received digital voice signal.

2. The method as claimed in claim 1 , wherein before conducting the voice interaction with the external device by adopting the MIC lines and the SPK lines, the method further comprises:

comparing the micro USB3.0-B female connector interface with an USB2.0 interface to determine a first pair of differential signal lines and a second pair of differential signal lines; and

configuring the first pair of differential signal lines as the MIC lines and configuring the second pair of differential signal lines as the SPK lines.

3. The method as claimed in claim 2 , wherein configuring the first pair of differential signal lines as the MIC lines and configuring the second pair of differential signal lines as the SPK lines comprises: configuring a MicB_SSTX− line and a MicB_SSTX+ line among the signal lines of the micro USB3.0-B female connector interface as the MIC lines; and configuring a MicB_SSRX− line and a MicB_SSRX+ line among the signal lines as the SPK lines.

4. The method as claimed in claim 1 , wherein the method is applied to a mobile terminal and the external device is an on-board system.

5. A device for voice interaction, comprising:

a micro USB3.0-B female connector interface, arranged to determine that an external device adopts USB2.0 standard for transmission and the external device supports voice function; and conduct voice interaction with the external device by adopting customized MIC lines and SPK lines;

wherein the micro USB3.0-B female connector interface is further arranged to conduct the voice interaction with the external device by adopting the MIC lines and the SPK lines via a USB shielding line which converts a USB3.0-A interface into a micro USB3.0-B male connector interface, wherein after generating a to-be-sent analogue voice signal through a processing of digital-to-analogue conversion, data voice information to be sent to the external device is sent to the external device via the USB shielding line, and/or, after a processing of analogue-to-digital conversion, an analogue voice signal received from the external device via the USB shielding line generates a to-be-received digital voice signal.

6. The device as claimed in claim 5 , wherein the micro USB3.0-B female connector interface is further arranged to: compare the micro USB3.0-B female connector interface with an USB2.0 interface to determine a first pair of differential signal lines and a second pair of differential signal lines, and configure the first pair of differential signal lines as the MIC lines and configure the second pair of differential signal lines as the SPK lines to conduct the voice interaction with the external device.

7. The device as claimed in claim 6 , wherein the micro USB 3.0-B female connector interface 10 is further arranged to configure a MicB_SSTX− line and a MicB_SSTX+ line as the MIC lines, and configure a MicB_SSRX− line and a MicB_SSRX+ line in the wire cable as the SPK lines.

8. A system for voice interaction, comprising the device as claimed in claim 7 and a USB shielding line which converts a USB3.0-A interface into a micro USB3.0-B male connector interface.

9. A system for voice interaction, comprising the device as claimed in claim 6 and a USB shielding line which converts a USB3.0-A interface into a micro USB3.0-B male connector interface.

10. The device as claimed in claim 5 , wherein the device is applied to a mobile terminal and the external device is an on-board system.

11. A system for voice interaction, comprising the device as claimed in claim 5 and a USB shielding line which converts a USB3.0-A interface into a micro USB3.0-B male connector interface.
