Abstract

The invention is suitable for the technical field of signal processing and provides an acoustic model training method and device, terminal equipment and a storage medium. The method comprises steps of n statement vectors of training voice being extracted through a statement coding module to obtain statement features of the training voice; extracting n segments of phoneme vectors of the training voice through a phoneme coding module to obtain phoneme features of the training voice; inputting the n statement vectors and the n segments of phoneme vectors into an acoustic modeling module to obtain the acoustic information of the training voice; and inputting the acoustic information of the training voice into a decoding module to obtain a spectrogram of the training voice. According to the training voice and the spectrogram of the training voice, the parameters of the decoding module are updated, rich fine-granularity acoustic information can be captured from the training voice, the demand of the training voice is reduced, acquisition difficulty of a data set is reduced, and the quality of the data set is improved; and thus, naturalness of speech synthesis and similarity between the speech synthesis and the speaker sound are improved.

Description

technical field [0001] The present application belongs to the technical field of signal processing, and in particular, relates to an acoustic model training method, apparatus, terminal device and storage medium. Background technique [0002] Speech synthesis can convert text into corresponding speech, and has been widely used in smart mobile terminals, smart homes, smart robots, and in-vehicle equipment. A speech synthesis system usually includes an acoustic model and a language model. The acoustic model is used to extract the acoustic information of speech to form a spectrogram, and the language model is used to form a corresponding text according to the spectrogram. After the speech synthesis meets the basic requirements of clear voice, the development focus shifts to improving the naturalness of speech synthesis and the similarity with the speaker's voice, which puts forward further requirements for the performance of the acoustic model. [0003] In order to improve the ...
