Embodiment 1

[0024] In this embodiment, the speakers in the channel data to be extracted are the first speaker and the second speaker. Based on the method provided in this embodiment, the audio belonging to the first speaker and the second speaker can be quickly Effective extraction. For details, please refer to figure 1 , figure 1 A flow chart of the method for quickly extracting telephone channel data provided by Embodiment 1 of the present application is shown. Such as figure 1 As shown, the method comprises the steps of:

[0025] S101. Obtain effective audio in channel data to be extracted.

[0026] Specifically, the channel data to be extracted may be monaural channel data collected during a conversation between two people. In this embodiment, VAD (Voice Activity Detection, Voice Activity Detection) technology can be used to clean the data and retain valid audio. Wherein, valid audio refers to audio data containing voice. It can be understood that during a telephone call, usually...

Embodiment 2

[0051] In this embodiment, there may be more than two speakers in the channel data to be extracted, that is, the first speaker and at least two other speakers. Based on the method provided in this embodiment, the speakers belonging to each speaker can be separately Audio for fast and efficient extraction. For details, please refer to Figure 5 , Figure 5 A flow chart of the method for quickly extracting telephone channel data provided by Embodiment 2 of the present application is shown. Such as Figure 5 As shown, the method comprises the steps of:

[0052] S501. Obtain effective audio in channel data to be extracted.

[0053] Wherein, the channel data to be extracted in this embodiment may be monophonic channel data including more than two speakers, or binaural channel data collected during a conversation between two or more speakers.

[0054] S502. Divide the valid audio into several segments.

[0055] S503. Determine the segment belonging to the first speaker and the...

Abstract

The invention relates to the technical field of human computers, and provides a telephone channel data rapid extraction method, which comprises the following steps: obtaining an effective audio in to-be-extracted channel data, the to-be-extracted channel data being channel data acquired in a conversation process of at least two persons; segmenting the effective audio into a plurality of segments; determining a fragment belonging to the first speaker and a speaker change fragment by comparing the voiceprint features of the adjacent fragments; and according to the fragment of the first speaker and the change fragment, clustering the fragments belonging to the first speaker in the effective audio to obtain the effective audio of the first speaker. Based on the method provided by the embodiment of the invention, the effective audio of the speaker can be automatically and quickly extracted without depending on manpower, so that the cost is saved and the data acquisition efficiency is improved. In addition, the invention also provides a telephone channel data rapid extraction device and a computer readable storage medium.

Description

technical field [0001] The present application relates to the field of computer information technology, in particular to a method, device and computer-readable storage medium for quickly extracting telephone channel data. Background technique [0002] The field of artificial intelligence usually requires a large amount of data to support, such as training samples, input layer data, etc., all of which require preprocessing including collection, cleaning, classification, labeling, and construction. These preprocessing tasks are mainly done manually, so whether it is Both the training of the algorithm model and the data required for the model application require a lot of labor costs and are time-consuming. [0003] Artificial intelligence technology will also encounter similar problems in the application of telephone calls. Telephone channel data is mainly divided into two categories: one is binaural data, and the two channels store the audio of the speakers at both ends of the...
