Speech Perception And Production

The objective of this experiment was to quantify and localize the effects of wearing the nuclear, biological, and chemical (NBC) M40 protective mask and hood on speech production and perception. A designated speaker's vocalizations of 192 monosyllables while wearing an M40 mask with hood were digitized and used as speech stimuli. Another set of speech stimuli was produced by recording the same individual's vocalizing the same monosyllables without the mask and hood. Participants listened to one set of stimuli during two sessions, one session while wearing an M40 mask with hood and another session without the mask and hood. The results showed that wearing the mask with hood gave most detrimental effects on the sustention dimension acoustically for both speech perception and production. The results also showed that wearing it was detrimental on vocalizing and listening to fricatives and unvoiced-stops. These results may be due to the muffling effect of the voicemitter in speech production and the filtering effects of the voicemitter and the hood material on high frequency components during both speech production and perception. This information will be useful for designing better masks and hoods. This methodology also can be used to evaluate other speech communication systems.

The purpose of this chapter is to review research conducted over the past two decades on the perception of synthetic speech by individuals with intellectual, language, and hearing impairments. Many individuals with little or no functional speech as a result of intellectual, language, physical, or multiple disabilities rely on non-speech communication systems to augment or replace natural speech. These systems include Speech Generating Devices (SGDs) that produce synthetic speech upon activation. Based on this review, the two main conclusions are evident. The first is that persons with intellectual and/or language impairment demonstrate greater difficulties in processing synthetic speech than their typical matched peers. The second conclusion is that repeated exposure to synthetic speech allows individuals with intellectual and/or language disabilities to identify synthetic speech with increased accuracy and speed. This finding is of clinical significance as it indicates that individuals who use SGDs become more proficient at understanding synthetic speech over a period of time.
