title = "Speech coding based on vector quantization for a tactile vocoder hearing device",
abstract = "A portable digital speech processing system for deaf patients is described. This real-time processing system provides appropriate information to a ten-channel tactile prosthesis depending on the speech signal characteristics to be perceived. The system is based on three chips: a Codec TCM29C13, a DSP (digital signal processor) TMS320E17, and a full custom integrated BiCMOS circuit. Speech coding is based on LPC (linear predictive coding) coefficient estimation and vector quantization. The architecture of this portable low-power unit allows a marked improvement in synthetic vowel discrimination.",
