The invention discloses a sound pickup and playback circuit, comprising: a microphone array module, used to collect audio signals and output a first audio signal; a first wireless audio transceiver module, used to receive audio signals from a wireless microphone and output a second audio signal signal, and is used to transmit the audio playback signal; the audio processing module processes the first audio signal or the second audio signal and outputs the audio playback signal; the first audio playback module is used to receive and play the audio playback signal; the control module uses For outputting the first control signal and the second control signal; the audio input switching module, according to the first control signal, the first audio signal or the second audio signal is input to the audio processing module; and the audio output switching module, according to the second control The signal sends the audio playback signal to the first audio playback module or the first wireless audio transceiver module. The invention can improve the success rate of speech recognition and improve user experience.
Description
technical field [0001] The invention relates to the technical field of audio switching, in particular to a sound pickup and playback circuit and system, and a sound pickup and playback switching method. Background technique [0002] In the current existing technology, the voice interaction technology uses the remote sound pick-up scheme of the microphone array. The user can use this function in a relatively quiet environment of 3-5 meters. The microphone array can collect the user's voice signal and transmit it to the processor. Process and output and play. However, when the user is far away from the microphone array or the surrounding environment is noisy, the effect of the sound signal collected by the microphone array will be greatly reduced, thereby affecting the quality of voice output and degrading user experience. Contents of the invention [0003] In order to solve the above technical problems, the first aspect of the present invention provides a sound pickup and ...
