Embodiment 1

[0084] This embodiment provides a phone background music detection model, such as figure 1 As shown, the telephone background music detection model includes an input layer 1, an audio CNN layer 2, a splicing layer 3, a convolutional layer 4, a fully connected layer 5, and an output layer 6.

[0085] The input layer 1 is used to receive the frame information of the phone background music, and perform feature extraction on the frame information to obtain features of preset dimensions.

[0086] The audio CNN layer 2 includes several parallel one-dimensional convolutional layers 21, the first pooling layer 22, and the Flatten layer 23. The audio CNN layer 2 is used to separately analyze the features of the preset dimensions through each one-dimensional convolutional layer 21. Perform convolution calculation and obtain the first feature data corresponding to each one-dimensional convolution layer 21; the first pooling layer 22 is connected to the tail of the one-dimensional convolu...

Embodiment 2

[0094] This embodiment provides a kind of telephone background music detection method, the telephone background music detection method application embodiment 1 in the telephone background music detection model is realized, as figure 2 Shown, the phone background music detection method includes:

[0095] Step 11, carry out mute cutting to input telephone voice and obtain audio segment;

[0096] Step 12, the audio segment is divided into frames to obtain corresponding frame information;

[0097] Step 13: Input the frame information into the telephone background music detection model to obtain the judgment result.

[0098] When the OTA intelligent customer service communicates with the guest or the hotel in real time through the phone, the guest or the hotel will have an automatic response ringtone, the hotel’s pre-recorded answer system recording, waiting beeps, hotel welcome words, and task buttons Process recordings, hotel advertisements, and English-sounding advertisements...

Embodiment 3

[0142] This embodiment provides a kind of telephone background music detection system, the telephone background music detection system application embodiment 1 in the telephone background music detection model is realized, as Figure 6 As shown, the phone background music detection system includes a cutting module 201, a framing module 202, a preprocessing module 203, a training module 204 and a prediction module 205;

[0143] The cutting module 201 is used for silently cutting the input telephone voice to obtain audio segments.

[0144] The framing module 202 is used for framing the audio segment to obtain corresponding frame information.

[0145] When the OTA intelligent customer service communicates with the guest or the hotel in real time through the phone, the guest or the hotel will have an automatic response ringtone, the hotel’s pre-recorded answer system recording, waiting beeps, hotel welcome words, and task buttons Process recordings, hotel advertisements, and Engl...

Abstract

The invention discloses a telephone background music detection model, method and system, a device and a medium. An input layer of a telephone background music detection model is used for receiving frame information of telephone background music and carrying out feature extraction on the frame information to obtain features of a preset dimension. An audio CNN layer is used for performing convolution calculation on features of a preset dimension through each path of one-dimensional convolution layer and obtaining first feature data corresponding to each path of one-dimensional convolution layer.A splicing layer is used for connecting the first feature data to obtain second feature data. Multipleconvolution layer are used for performing layer-by-layer convolution calculation on the second feature data to obtain third feature data. A full connection layer is used for obtaining the probability of frame information according to the third feature data; and an output layer is used for obtaining a judgment result of whether to call background music according to the probability. The telephone background music detection model can rapidly and accurately detect the sound content of the telephone background music, and the generalization ability of the telephone background music detection model is improved.

Description

technical field [0001] The invention relates to the field of speech algorithms, in particular to a method, system, device and medium for detecting a background music of a telephone. Background technique [0002] In the OTA (online travel) industry, when the OTA intelligent customer service or human customer service communicates with guests, enterprises or hotels in real time by telephone, if the guests, enterprises or hotels set up automatic response ringtones, or record in advance Good answer system recordings, waiting beeps, welcome words, task-type button process recordings, advertisements, and English pronunciation advertisements that contain sound content such as advertising background music, the intelligent customer service will understand the sound of the advertising background music as normal pronunciation The content may be regarded as a normal conversation and responded directly, resulting in wrong answers; while the human customer service needs to wait until the r...
