Abstract
Presented herein are techniques to enhance pitch coding in hearing devices, such as cochlear implants, by utilizing place of stimulation to more accurately and distinctly code frequency information pertaining to individual harmonics of a target harmonic signal, such as voiced vowel in speech or a harmonic tone in music. The techniques presented herein can be combined with a temporal pitch enhancement system to provide a combined system which operates over the voice and musical pitch range in which for example, pitch perception for low fundamental frequencies (F0s) is enhanced via the temporal pitch enhancement method and perception for higher F0s is enhanced via the spectral-place pitch coding method described in the present application. The techniques presented herein can also have application to enhancing coding of pitch and speech in acoustic hearing devices such as hearing aids.
