Abstract

The invention provides a voice data annotation method and device and electronic equipment. The method comprises the steps: inputting voice data and a text into a pre-trained acoustic model, and acquiring the posterior probability of each frame of voice for all phonemes and an alignment result; determining each first voice frame corresponding to each phoneme according to the alignment result; for each phoneme in the text, determining whether the phoneme is a doubt phoneme according to the posterior probability of the first voice frame for the phoneme; and performing first marking on each doubt phoneme in the text. According to the voice data annotation method provided by the invention, the accuracy of a manual voice data annotation result can be improved, and the manpower consumption of manual voice data annotation can be saved.

Description

technical field [0001] The invention relates to the technical field of voice recognition, in particular to a voice data labeling method and device, and electronic equipment. Background technique [0002] At present, with the breakthrough of artificial intelligence technology, voice, as an important part of human-computer interaction, is becoming more and more prominent. However, due to the large differences in the corresponding voices in different regions, it is necessary to label a large amount of voice data in order to establish an effective acoustic model. [0003] In speech data annotation, text needs to be annotated according to the sound. Generally, a large number of outsourced personnel are used for data labeling, and the marked data is checked and accepted to determine whether the correct rate of labeling meets the standard. Relying entirely on manual data labeling not only consumes a lot of human resources, but also is prone to errors due to manual operations. C...
