PROBLEM TO BE SOLVED: To solve such problem that a speech input device used in a conventional communication device or the like requires utterance by vocal chords, which may become nuisance for surrounding people and the communication content leak may occur. SOLUTION: A vibrator to take place of vocal chords is closely attached to a user neck. The vibration generated by the vibrator is formed into a speech by modifying the tongue position and form of the cavity of mouth. The speech sound is collected by a microphone such as a contact type microphone closely attached to the user neck. Thus, it is possible to provide a speech input device capable of communication and speech input without leaking the speech outside. COPYRIGHT: (C)2005,JPO&NCIPI
