Abstract

The embodiment of the invention discloses a data processing method and device. The method comprises the following steps that: a fundamental frequency curve of target audio data is acquired, wherein the fundamental frequency curve comprises at least one fundamental frequency effective interval, and the fundamental frequency effective interval is an interval of a fundamental frequency value of the fundamental frequency curve in a target range; voice recognition is performed on the target audio data to determine phonemes corresponding to the fundamental frequency effective intervals and time information of each phoneme; and if the phonemes corresponding to a target fundamental frequency effective interval include mute phonemes, the time information of adjacent phonemes of the mute phonemes isadjusted according to the positions of the mute phonemes in a phoneme sequence corresponding to the target fundamental frequency effective interval, so that the adjacent phonemes after time information adjustment cover the mute phonemes, wherein the target fundamental frequency effective interval is any fundamental frequency effective interval in the at least one fundamental frequency effective interval. By adopting the method and the device, the time alignment accuracy of the phonemes in the audio can be improved.

Description

technical field [0001] The present application relates to the technical field of the Internet, and in particular to a data processing method and device. Background technique [0002] In the field of music applications, the realization of business application functions such as song content analysis, song detail teaching, and singing voice synthesis requires the use of time information of phonemes in audio (songs). At present, the main way to determine phonemes and time information is to use existing technologies to obtain phonemes at different times, generally through automatic speech recognition technology (Automatic Speech Recognition, ASR), to perform phoneme recognition and alignment on input audio. However, using the existing technology, only rough phoneme alignment results in different time intervals can be obtained, the accuracy of phoneme alignment in time is low, and the accuracy of phoneme time information is poor. Contents of the invention [0003] Embodiments o...
