Abstract

The invention relates to a telephone warning tone identification method, device, computer equipment and a computer readable storage medium system; the method comprises the following steps: obtaining aplurality of voice matching templates of the same type of telephone; inputting each voice matching template into a pre-trained voice matching model, wherein the voice matching model is used for calculating the correct rate of the voice matching template identifying the telephone warning tone under different preset thresholds, and selecting the correct rate with the highest value to serve as the target correct rate corresponding to the voice matching template; selecting the voice matching plate with the highest target correct rate from the plurality of voice matching templates, and using the selected template as the target voice matching template of the same type of telephone; using the target voice matching template to identify the telephone warning tone of the same type of telephone. Themethod can improve the telephone warning tone identification accuracy, can improve the identification efficiency, and solves the defects that a conventional voice identification method is low in accuracy.

Description

technical field [0001] The present invention relates to the technical field of speech recognition, in particular to a landline prompt sound recognition method, device, computer equipment and computer-readable storage medium. Background technique [0002] In the field of telephone communication, the user dials the number of the called party, and the local switching center recognizes the call signal converted from the dialed number, triggering the relevant voice prompt tone of the user's landline, which is convenient for the user to judge whether the call is successful. Therefore, for The correct recognition of the relevant voice prompts is very important. [0003] At present, for the recognition of related voice prompts, such as the voice prompts of certain types of landlines, the time-domain signal of the voice prompts of the empty number is usually converted into a frequency-domain signal, and then the spectral characteristics of the frequency-domain signal are extracted. ...
