Abstract

The invention discloses a timestamp determination method of a dry sound audio, electronic equipment and a storage medium. The method comprises the following steps: acquiring a target dry sound audio and a standard dry sound audio corresponding to the target dry sound audio; extracting a first basic audio feature of the target dry sound audio and a second basic audio feature of the standard dry sound audio; respectively inputting the first basic audio feature and the second basic audio feature into a feature extraction model based on a neural network to respectively obtain a first enhanced audio feature corresponding to the first basic audio feature and a second enhanced audio feature corresponding to the second basic audio feature; aligning the first enhanced audio feature and the second enhanced audio feature by using a dynamic time warping method, and determining a corresponding relationship between each frame of audio in the standard dry sound audio and each frame of audio in the target dry sound audio; and the timestamp information of the target dry sound audio is determined based on the timestamp information of the standard dry sound audio and the corresponding relationship, so that the precision of determining the timestamp of the dry sound audio is improved.

Description

technical field [0001] The present application relates to the technical field of audio processing, and more particularly, to a method, apparatus, electronic device, and computer-readable storage medium for determining a timestamp for dry audio. Background technique [0002] In recent years, the application of online karaoke platforms in intelligent technology has become increasingly prominent. The karaoke platform can support the one-key repair function of most songs, realize the effect of automatically optimizing the user's singing works, and reduce the difficulty and difficulty of online karaoke songs. threshold. In the one-key sound repair function, the automatic analysis of the time stamp information of the user's dry voice is the premise of automatic sound repair. [0003] In the related art, the user dry voice timestamp information may be estimated based on the automatic speech recognition technology of HMM (Hidden Markov Model, Hidden Markov Model) or the forced alig...
