Preparing for the full-fledged aged society, measures to prevent senility are required. Senility is prevented by extracting signals of prescribed bands from a speech signal using a first bandpass filter section having a plurality of bandpass filters, extracting the envelopes of each frequency band signal using an envelope extraction section having envelope extractors, applying a noise source signal to a second bandpass filter section having a plurality of bandpass filters and extracting noise signals corresponding to the prescribed bands, multiplying the outputs from the first bandpass filter section and the second bandpass filter section in a multiplication section, summing up the outputs from the multiplication section in an addition section to produce a Noise-Vocoded Speech Sound signal, and presenting the Noise-Vocoded Speech Sound signal for listening.
An apparatus for preventing senility that constructs a Noise-Vocoded Speech Sound signal produced by dividing at least a portion of a speech signal into a frequency band signal and subjecting the frequency band signal to noise degradation, and outputs the Noise-Vocoded Speech Sound signal.
An apparatus for preventing senility that constructs a Noise-Vocoded Speech Sound signal produced by dividing at least a portion of a speech signal into a plurality of frequency band signals and subjecting the frequency band signals to noise degradation, and outputs the Noise-Vocoded Speech Sound signal.
An apparatus for preventing senility that stores a Noise-Vocoded Speech Sound signal produced by dividing at least a portion of a speech signal into a single frequency band signal or a plurality of frequency band signals and subjecting the frequency band signal or the frequency band signals to noise degradation, and comprises a speech source signal section for outputting the Noise-Vocoded Speech Sound signal.
A method for preventing senility constructing a Noise-Vocoded Speech Sound signal produced by dividing at least a portion of a speech signal into a frequency band signal and subjecting the frequency band signal to noise degradation, and outputting the Noise-Vocoded Speech Sound signal.
A method for preventing senility constructing a Noise-Vocoded Speech Sound signal produced by dividing at least a portion of a speech signal into a plurality of frequency band signals and subjecting the frequency band signals to noise degradation, and outputting the Noise-Vocoded Speech Sound signal.
A method for preventing senility that reads out and outputs a stored Noise-Vocoded Speech Sound signal produced by dividing at least a portion of a speech signal into a single frequency band signal or a plurality of frequency band signals and subjecting the frequency band signal or the frequency band signals to noise degradation.
