Abstract :
Cochlear implants are considered the most successful sensory protheses in the world, having restored hearing for more than a million people (Carlyon and Goehring, 2021; Zeng 2022). On average, cochlear implant users achieve 70-80% speech recognition in quiet (). Contrary to the success with speech understanding, cochlear implant users face challenges perceiving pitch, affecting their ability to understand speech in noise, recognising speech tones and enjoying music. In this thesis, we study the current processing strategies in CIs that aim to improve the delivery of pitch information, as well as exploring some hypothetical options that might further improve pitch perception for CI users.
