AI Technical Summary

Technical Problem

Existing technologies lack accuracy in determining the number of times and frequency of beeps when testing alert devices, especially when multiple alerts are played simultaneously, which affects the reliability of test results.

Method used

By acquiring the envelope square wave data of the audio data, the time period corresponding to the a-th band in the square wave data is determined, the cross-correlation function between the target audio segment and the audio data is calculated, the first and second target peak points are identified, and the playback information is determined based on the number and time interval of these peak points.

Benefits of technology

It improved the accuracy of the number and frequency of prompt tone playback, enhanced the reliability of equipment test results, reduced manual intervention, and saved labor costs.

Abstract

The application discloses a prompt sound statistical method, device, equipment and readable storage medium. The prompt sound statistical method comprises the following steps: obtaining square wave data corresponding to an envelope line of collected audio data; determining a time period corresponding to an a-th wave band in the square wave data; obtaining audio corresponding to the time period from the audio data to obtain a target audio segment; calculating the similarity between the target audio segment and each collected segment in the audio data; determining a first target peak point and a target threshold in a cross-correlation function; determining at least one second target peak point in the plurality of similarities; and determining the playing information of the prompt sound in the audio data according to the total number of the first target peak point and the second target peak point and the time interval between the first target peak point and the second target peak point. According to the embodiment of the application, the accuracy of determining the playing number or frequency of the prompt sound can be effectively improved, and the reliability of the test result of the device outputting the prompt sound is improved.
