Intelligibility of bone-conducted speech at different locations compared to air-conducted speech
Bone-conduction transducers offer a unique advantage for radio communication systems, allowing sound transmission while the ear canals remain open for access to environmental sounds, or plugged for blocking of environmental sounds. This study compared the intelligibility of noise-degraded speech presented through bone-conduction hearing administered at different locations, and through air-condu...
متن کاملReconstruction filter design for bone-conducted speech
Bone-conducted speech is of low intelligibility, but its quality is not affected by noise. In this paper, we take into account such propertes of bone-conducted speech, and address a digital filter to reconstruct the quality of the bone-conducted speech signal obtained from a speaker. The reconstruction filter design method is derived based on a model assumption of pronunciation. Experimental re...
متن کاملModel-based speech enhancement using a bone-conducted signal.
Codebook-based single-microphone noise suppressors, which exploit prior knowledge about speech and noise statistics, provide better performance in nonstationary noise. However, as the enhancement involves a joint optimization over speech and noise codebooks, this results in high computational complexity. A codebook-based method is proposed that uses a reference signal observed by a bone-conduct...
متن کاملEffects of rise-time of stimulus on auditory N1m to air-conducted, bone-conducted audible and bone-conducted ultrasonic sounds
condition elicited smaller N1m amplitude than the incongruent condition. In both hemispheres, the stepwise multiple regression revealed that the reduction rate of N1m amplitudes between the presented conditions correlated significantly with the source activities in motor and superior temporal areas. The present study suggested that some sensorimotor mediated prediction modulated auditory activi...
متن کاملAmplitude and amplitude variation of emotional speech
The present study introduces a recording technique to maintain all dynamic information of even full-blown emotional speech, and investigates the effect of emotion class, speaker, and sentence type on the amplitude of speech. The results show that the factors emotion class and speaker are highly significant and that the former explains half of the variance while the latter explains only one nint...
