Abstract

A 16-channel electrotactile digital vocoder for artificial hearing is developed that uses FFT spectral analysis techniques instead of the conventional bank filtering. Temporal coding of individual electrotactile current pulses is accomplished by a neuronlike encoding algorithm. This design is implemented with dual processors and used in psychophysical experiments to improve speech information transmission. Results indicate no loss of information compared with conventional designs. Such digital vocoders offer the advantages of reliable operation and signal enhancement to improve tactile speech perception by the deaf.
