[Invited Talk] Voice conversion based on sparse representation and its application to articulation disorders
Tetsuya Takiguchi (Kobe Univ.) SP2014-66
Abstract (in Japanese) (See Japanese page) 
(in English) In recent years, approaches based on sparse representations have gained interest in a broad range of signal processing. For example, Non-negative Matrix Factorization (NMF) is a well-known sparse-based approach for source separation and speech enhancement. In this paper, a voice conversion technique based on a sparse representation of speech using NMF is introduced, and it is applied to a person with an articulation disorder resulting from athetoid cerebral palsy. Also, in this paper, a voice conversion method using restricted Boltzmann machine, which is an important technique for deep learning, is introduced.
