A device (1) for transmitting speech information to the human body,
comprising:
a microphone (2) for inputting speech from an external source;
a speech signal processor (20) that produces a consonant-clarified signal
based on the input speech signal;
a carrier signal generator (6) that produces a carrier signal;
an amplitude modulator (8) that modulates the amplitude of the carrier
signal based on the consonant-clarified signal; and
a vibrator (12) that transmits mechanical vibrations based on the
amplitude-modulated output signal;
the speech signal processor (20) comprising:
a consonant extracting unit that extracts the consonant parts from the
speech signal; and
a repetition processing unit that adds the extracted consonant parts to
the speech signal to produce a consonant-clarified signal in which each
of the consonant parts of the speech signal is repeated two or more
times. This speech information transmitting device realizes good
discriminability of speech information.
