Test method for cochlear implant stimulation strategies

摘要

An arrangement and method for hearing implant signal processing is described. A hearing implant signal processor converts a speech signal input into multi-channel electrical stimulation signals for a cochlear implant electrode array. A feature adjustment module adjusts feature resolution of the electrical stimulation signals to produce a corresponding sequence of cochlear stimulation feature vectors. A speech recognition vector pre-processor maps the cochlear stimulation feature vectors into corresponding speech recognition feature vectors. A speech recognition engine evaluates the speech recognition features vectors with probabilistic state sequence models to produce speech recognition outputs corresponding to the speech signal input.
