Title: CALL MODE SWITCHING METHOD AND TERMINAL
Abstract:
Provided in an embodiment of the present invention are a method and a terminal for switching call modes. The method comprises: establishing a call connection between a first terminal connected having a peripheral headset and a remote device; the first terminal collecting a first sound signal by means of a microphone of the peripheral headset; the first terminal converting the collected first sound signal to first audio data; the first terminal determining whether the first audio data is valid data; if the first audio data is invalid data, the first terminal switching to collecting a second sound signal by means of a microphone of the first terminal. Thus, the terminal may automatically determine which call mode is to be used according to actual situations, preventing the call from being cut off by mistake while also eliminating manual operation steps for a user.
