Abstract

The invention discloses a voice data processing method and a voice data processing device. The voice data processing method comprises the following steps: acquiring the I-Vector of each of a plurality of voice samples, and determining a target seed sample in the plurality of voice samples; respectively calculating the cosine distances between the I-Vector of the target seed sample and the I-Vectors of the target residual voice samples, wherein the target residual voice samples are the voice samples besides the target seed sample in the plurality of voice samples; and at least filtering from the plurality of voice samples or the target residual voice samples according to the cosine distances to obtain a target voice sample, wherein the cosine distance between the I-Vector of the target voice sample and the I-Vector of the target seed sample is higher than a first preset threshold value. With the adoption of the method and the device, the technical problem that in the relevant technologies, cleansing can not be carried out on voice data by adopting a manual annotation method, so that the voice data cleansing efficiency is low is solved.

Description

technical field [0001] The invention relates to the field of data processing, in particular to a voice data processing method and device. Background technique [0002] In various fields of artificial intelligence, data is crucial, and in many cases the quality of data plays a decisive role. However, the quality of data in the actual situation is mostly uneven, and it needs to be processed further. Data processing generally refers to removing the "noise" in the data and retaining the real data needed. In the field of voiceprint recognition, the voiceprint samples of a specific person obtained through the Internet are in most cases impure. In addition to noise such as non-human voices, they may also contain the voices of other people. How to clean out the noise and other human voices, and only keep the voiceprint voice samples of this specific person is the main problem we are facing today. [0003] At present, in order to obtain voice samples of a specific person's voicepr...
