Problems solved by technology

Therefore, if one or several microphones in the microphone array fails, as long as not all the microphones in the array fail at the same time, then when the voice signal is collected and detected, it cannot be detected through simple recording as in the detection of a single microphone product.

Abstract

The invention discloses a microphone array fault detection method and a microphone array fault detection device.The microphone array fault detection method comprises steps that an independent samplingdata set of a signal acquisition channel of each microphone of a microphone array is acquired; whether speech signals exist in each independent sampling data set is detected. By adopting the microphone array fault detection method, whether the signal acquisition channel of each microphone of the microphone array is faulted can be detected.

Description

Technical field [0001] The invention relates to the field of microphone arrays, and in particular to a method and device for detecting faults of a microphone array. Background technique [0002] In the fields of smart home, artificial intelligence and car navigation, voice interaction is an important way of human-computer interaction. The microphone is the most common voice collection tool. When only an isolated microphone is used, for example, in order to obtain a clearer voice command, the user needs to be as close to the microphone as possible to reduce the impact of environmental noise. This method limits the user's activities The scope is very inconvenient. Therefore, how to get a clearer voice has always been an important subject of research. [0003] Many different technical solutions have been proposed to improve the quality of the voice collected by the microphone. For example, the voice processing technology based on the microphone array has become a recent research hot...
