Synthetic audio output method and apparatus, storage medium, and electronic device

Abstract

This application provide a synthetic audio output method and apparatus, a storage medium, and an electronic device. The method includes: inputting input text and a specified target identity identifier into an audio output model; extracting an identity feature sequence of a target identity by an identity recognition model; extracting a phoneme feature sequence corresponding to the input text by an encoding layer of a speech synthesis model; superimposing and inputting the identity feature sequence of the target identity and the phoneme feature sequence into a variable adapter of the speech synthesis model; and after duration prediction and alignment, energy prediction, and pitch prediction are performed on the phoneme feature sequence by the variable adapter, outputting a target Mel-frequency spectrum feature corresponding to the input text through a decoding layer of the speech synthesis model; and inputting the target Mel-frequency spectrum feature into a vocoder to output synthetic audio.
