The relative contributions of spectral and temporal cues to voice pitch perception in cochlear implant (CI) users remain unclear. This study aimed to directly quantify these contributions in dynamic speech stimuli with clinical n-of-m processors.

Discussion
Signed responses from readers of the wire.
Audiologists programming cochlear implants with n-of-m strategies should be aware that pitch perception relies on both spectral and temporal cues in a voice-pitch-dependent way, but specific programming changes cannot yet be recommended from this single study alone.
Understanding how cochlear implant users decode voice pitch cues could guide the design of better sound-coding strategies that improve speech and music perception outcomes.
- 01n-of-m CI strategies activate only a subset of electrodes per cycle, affecting both spectral and temporal information available.
- 02Relative weighting of spectral vs. temporal cues for pitch perception shifts depending on voice fundamental frequency.
- 03Findings have implications for optimizing cochlear implant signal processing to improve voice pitch discrimination.
- 04Study quantifies cue contributions, providing a framework for future coding strategy refinement.
