EXTRACTION OF PITCH FROM THE TRACHEA
Abstract
For decades, speech researchers have recognized that accurate pitch information is prerequisite to the synthesis or reconstitution of speech that has been broken into its basic parts for any reason, such as communication over restricted bandwidth media. In a series of experiments investigating tracheal pitch extraction according to a methodology suggested in a Japanese paper, the Speech Research Branch, AFCRL Communication Sciences Laboratory succeeded in achieving reasonably accurate real time pitch extraction. The method has a limitation in that the talker must wear a special appliance.
