Abstract
Cochlear Implants are a marvelous option for hearing-impaired patients to perceive sound again, yet some people still cannot benefit from their implant. The resulting problem is a suboptimal pitch discrimination, which in turn is a vital factor for vowel identification. As an approach to solve this problem, this paper proposes an adaptive pitch transposition, which transposes a given signal to a fixed pitch in which the implant patient has the best comprehension. This pitch is called comfort pitch and has to be determined in a patient test. As a result of these considerations, APT was prototypically implemented in Octave/Matlab and serves as an evaluation platform for the quality of the produced signals. Furthermore, the comfort pitch is a new measure to tune the performance of a cochlear implant patient. The entire concept can be used as a preprocessing stage for state-of-the art speech processing algorithms in cochlear implants.
