Takehiko Kagoshima, Masami Akamine: Speech synthesis method. Kabushiki Kaisha Toshiba, Oblon Spivak McClelland Maier & Neustadt P C, April 22, 2003: US06553343 (82 worldwide citation)

A speech synthesis method subjects a reference speech signal to windowing to extract an aperiodic speech pitch wave from the reference speech signal. A linear prediction coefficient is generated by subjecting the reference speech signal to a linear prediction analysis. The aperiodic speech pitch wav ...
