Signal processing strategies for electrostimulated ear prostheses based on simulated nerve response.
Improvements to the coding strategy of prostheses for the profoundly deaf which can be implemented by the speech processors of these devices are suggested. Difficulties with vowel recognition are diagnosed as being due to nerve properties. These are studied with the aid of a model in order to find ways of overcoming the difficulties.
