Estimulação tátil aplicada ao ensino/aprendizagem da fala.

Abstract

Acoustic information can be transmitted to the deaf, using acoustic amplifies, cochlear implants and sensory substitution systems. The choice depends on characteristics and degree of hearing impairment. Tactile stimulation devices can be used as sensory substitute and have been developed since the beginning of the 20T H century, in this thesis the emphasis is on the investigation of the transformation of voice parameters into frequency of the pulsed tactile stimulus, in the context of the speech hearing on the part of the deaf for the Portuguese language. Different transformation schemes have been formulated and analyzed by simulation studies. The proposed transformations were also analyzed by vibrotactile perception sensitivity experiments.
