Voice conversion for various types of body transmitted speech

In this paper, we review our proposed statistical voice conversion approaches to enhancing various types of body transmitted speech captured with non-audible murmur (NAM) microphone. Body transmitted speech conversion is a potential technique to bring a new paradigm to human-to-human speech communication. In addition to our previously proposed methods of enhancing body transmitted unvoiced speech for silent speech communication and of enhancing body transmitted artificial speech for speaking aid, we further propose conversion methods of enhancing body transmitted voiced speech for noise robust speech communication. An experimental result demonstrates that the proposed methods yield significant improvements in quality of body transmitted voiced speech.
