Speech Recognition as a Function of Channel Capacity in a Discrete Set of Channels

摘要: There have been many attempts to perform a frequency analysis of speech and use the outputs this provide cutaneous stimulation. The results these tests left in doubt issue whether or not recognition is actually possible. In addition other difficulties, an optimum has never achieved. Instead, filtering configurations chosen essentially arbitrarily. systems considered may well had insufficient channel capacity for even event that tactile stimulators were arranged manner. paper, several sets finite band discrete channels filters considered. each was constrained fixed center corresponding so as be directly translatable position stimulator. Tests conducted measure auditory rate speech, resynthesized sum signals. From measurements with different numbers channels, representation function obtained. It anticipated will helpful choice configuration test actual recognition.
