|発明の名称||CONSONANT PROCESSING DEVICE, SPEECH INFORMATION TRANSMISSION DEVICE, AND CONSONANT PROCESSING METHOD|
PROBLEM TO BE SOLVED: To provide an inexpensive consonant processing device, an inexpensive speech information transmission device, and a consonant processing method which are capable of transmitting speech information almost in real time, in which signal processing is easy, and in which even the elderly or the people with hearing difficulty can distinguish a consonant even in the environment full of noise.
SOLUTION: The device comprises: a frame division part 1 for extracting a frame signal by each of a plurality of time frames from an inputted speech signal; a power calculation part 2 for calculating an average power or a sound pressure level for each frame signal; a comparison part 3 for mutually comparing the average powers and sound pressure levels between the frame signals; a consonant determination part 4 for determining whether the speech signal is a consonant or not based on the comparison result by the comparison part 3; and an amplification part that amplifies the amplification object point or the amplification object width of the speech signal when the consonant determination part 4 has determined that the speech signal is a consonant, but does not amplify it when the consonant determination part 4 has determined that the speech signal is not a consonant or a syllable end.
