چکیده
In this paper, we review our recent research on technologies for processing body-conducted speech detected with Non-Audible Murmur (NAM) microphone. NAM microphone enables us to detect various types of body-conducted speech such as extremely soft whisper, normal speech, and so on. Moreover, it is robust against external noise due to its noise-proof structure. To make speech communication more universal by effectively using these properties of NAM microphone, we have so far developed two main technologies: one is body-conducted speech conversion for human-to-human speech communication; and the other is body-conducted speech recognition for manmachine speech communication. This paper gives an overview of these technologies and presents our new attempts to investigate the effectiveness of body-conducted speech recognition.

Remodeling of the sensor for non-audible murmur (NAM)
We developed the next generation of skin-attachment sensors for sampling NAM (Non-Audible Murmur) signals by using soft silicone, which has an acoustic impedance close to that of human flesh, as the prime medium of vibration. With new NAM microphones we could sample expanded target voice signal, suppressing air conduction noise signal to low by the experiment of synchronous stereo sampling of a...

In this paper, we present the use of stethoscope and silicon NAM microphones in automatic speech recognition. NAM microphones are special acoustic sensors, which are attached behind the talker’s ear and can capture not only normal (audible) speech, but also very quietly uttered speech (non-audible murmur). As a result, NAM microphones can be applied in automatic speech recognition systems when ...
متن کاملNon-audible murmur enhancement based on statistical conversion using air- and body-conductive microphones in noisy environments
Non-Audible Murmur (NAM) is an extremely soft whispered voice detected by a special body-conductive microphone called a NAM microphone. Although NAM is a promising medium for silent speech communication, its quality is significantly degraded by its faint volume and spectral changes caused by body-conductive recording. To improve the quality of NAM, several enhancement methods based on statistic...

In this paper, we introduce the Stethoscopic Non-Audible Murmur (NAM) microphone, and we focus on its application in automatic speech recognition systems. The NAM microphone is attached behind the talker’s ear, and can capture very quietly uttered murmur (NAM speech). It is applicable in automatic speech recognition systems, when privacy is important in human-machine communication. Moreover, si...
متن کاملNon-audible murmur recognition based on fusion of audio and visual streams
Non-Audible Murmur (NAM) is an unvoiced speech signal that can be received through the body tissue with the use of special acoustic sensors (i.e., NAM microphones) attached behind the talker’s ear. In a NAM microphone, body transmission and loss of lip radiation act as a low-pass filter. Consequently, higher frequency components are attenuated in a NAM signal. Owing to such factors as spectral ...
