| Abstract(in English) | We studied silent-voice input system for practical use. The experiments were performed under two conditions, i. e., quiet and noisy circumstances. Under 40 dB(A) background noise, the sound pressure level of the point 300 mm distant from the vibrator was 40.2 dB(A) when the input of the transducer was I Vpp. We succeeded to receive the speech sounds which were produced by articulation motion without exhalation through both the normal and the contact-type microphones without any leak of audible sounds to outside. Then the two types of microphone were compared under the 60 dB(A) wihite noise. As a result, the contact-type microphone was less accessible to noise than the normal one. |
