[0002] At present, the microphone array will collect multi-channel voice signals, that is, each of the multiple microphones arranged on the microphone array will collect a channel voice signal, and when determining whether a microphone in the microphone array is faulty, it is usually judged manually. That is to say, the inspector judges whether the microphone is faulty based on his own experience, and this detection method not only has a heavy human burden, but also has low detection efficiency and accuracy

The invention relates to a faulty microphone detection method and device. The method includes: acquiring channel data collected by each of the several microphones; according to the channel data collected by each of the microphones, preliminarily determining damaged microphones and suspected undamaged microphones among the several microphones; The pre-judged channel data collected by the suspected undamaged microphones is re-judged to reconfirm whether there is a faulty microphone among the suspected undamaged microphones. Through the technical solution of the present invention, the faulty microphone in the microphone array can be automatically judged based on the channel data collected by each microphone, and the double judgment can also improve the judgment accuracy of the faulty microphone, and at the same time, the automatic judgment of the faulty microphone can also improve the detection accuracy. efficiency, and avoid human judgment.
Description
technical field [0001] The present invention relates to the field of terminal technology, in particular to a faulty microphone detection method and device. Background technique [0002] At present, the microphone array will collect multi-channel voice signals, that is, each of the multiple microphones arranged on the microphone array will collect a channel voice signal, and when determining whether a microphone in the microphone array is faulty, it is usually judged manually. That is, inspectors judge whether the microphone is faulty based on their own experience, and this detection method not only has a heavy human burden, but also has low detection efficiency and accuracy. Contents of the invention [0003] Embodiments of the present invention provide a faulty microphone detection method and device. Described technical scheme is as follows: [0004] According to the first aspect of the embodiments of the present invention, a faulty microphone detection method is provid...
