  • Publication number: 20240119922
    Abstract: An unsupervised text to speech system utilizing a lexicon to map input text to the phoneme sequence, which is expanded to the frame-level forced alignment with a speaker-dependent duration model. An alignment mapping module that converts the forced alignment to the unsupervised alignment (UA). Afterword, a Conditional Disentangled Sequential Variational Auto-encoder (C-DSVAE), serving as the self-supervised TTS AM, takes the predicted UA and a target speaker embedding to generate the mel spectrogram, which is ultimately converted to waveform with a neural vocoder.

  • Patent number: 9928088
    Abstract: A method, apparatus, server and system for implementing a web application. The method, for example, comprises: detecting an operating environment of a current web application; and automatically loading a component of a native version when it is detected that the current web application is operating on a light application platform; and automatically loading a component of a hypertext markup language (HTML) version when it is detected that the current web application is operating on a browser. By automatically loading the component of a native version and automatically loading the component of the HTML version, the disclosed method improves the compatibility of the web application so that the web application may complete the function thereof in various environments; and adopting an HTML tag development component reduces the development costs of the web application and increases the loading speed of the web application.
