Research on Parameter Feature for SPEAK-Based Speech Processing Strategy in Cochlear Implant

Spectral peak (SPEAK) algorithm is one of the most popular speech processing strategies in cochlear implant (CI). SPEAK-based speech processing strategy adopts filter bank to split frequency band, and provides some stimulating channels to CI electrode array. In this paper, we analyze the parameter feature for SPEAK-based speech processing strategy, adding to its theoretical and engineering value in algorithm research of new speech processing algorithm.
