Abstract

The invention discloses a sound box detection method and device, electronic equipment and a storage medium, and relates to the technical field of voice. According to the specific implementation scheme, the method comprises the steps of obtaining first audio data recorded by a microphone of the sound box in a white noise environment; analyzing the first audio data to obtain a first analysis result;and determining whether the microphone has defects or not according to the first analysis result. Therefore, complete machine testing can be carried out on the assembled loudspeaker box, consistencyof microphone testing is ensured, and accuracy of a detection result is improved.

Description

technical field [0001] The present application relates to speaker testing technology in the field of voice technology, in particular to a method, device, electronic equipment and storage medium for detecting a speaker. Background technique [0002] In the production of smart speakers, the most critical thing is the hardware acoustic quality of the speakers. If the acoustic quality is not up to standard, it will seriously affect the speech recognition effect. Therefore, in order to ensure the acoustic quality, it is necessary to carry out acoustic verification for the whole machine. [0003] At present, the microphone and speaker of smart speakers are generally tested separately, that is, the microphone is tested by the original factory of the microphone, and the speaker is tested for its Total Harmonic Distortion (THD) parameters through the Spk box on the production line. [0004] However, when the whole machine is assembled, the newly added structure will affect the cons...
