摘要： In a speech rate modification, correlation functions between different segments of input speech signal are computed by a correlator (17), then amplitude of input signal is controlled by two multipliers (19, 20) which multiply the input speech signal by an increasing window function and by a decreasing window function, or vice versa, respectively, produced by a window function generator (18), and then output signals of the multipliers (19, 20) are added each other by an adder (21) at such relative delay within one unitary segment as to make the larges value of the correlation function, and the input voice signal and the output of the adder (21) are selected by a multiplier (22), to be issued as rate-modified speech signal.

摘要： The present invention provides a music search system for conducting music search, which allows the user to easily listen to music matched to situation. The music search system includes a music data storage section 19, a location acquisition section 16, a parameter converting section 17, a music search section 20, and a reproducing section 15. The music data storage section 19 stores a plurality of pieces of music data so as to be associated with a corresponding one of music parameters. The location acquisition section 16 acquires a situation parameter. The parameter converting section 17 converts the situation parameter acquired by the location acquisition section 16 into the music parameter. The music search section 20 uses the music parameter resulted from conversion by the parameter converting section 17 to search through the plurality of pieces of music data stored in the music storage section 19 and selects a piece of music to be reproduced. The reproducing section 15 reproduces the piece of music selected by the music search section 20.

摘要： Low-frequency components (S2) are selected from the outputted analog sound signal (S1) so that a low-pitched sound signal is derived from the analog sound signal. A key of the low-pitched sound signal is lowered so that a very-low-pitched sound signal (S3) is derived from the low-pitched sound signal (S2). The analog sound signal (S1) and the very-low-pitched sound signal (S3) may be converted into corresponding sounds respectively (S4).

摘要： In a speech judging section, a speech portion and a speechless portion of an acoustic signal are judged. Data of the acoustic signal are stored in a buffer memory. A memory control section controls writing of the data judged to be the speech portion in the speech judging section into the buffer memory, and reading of the data from the buffer memory. A time-scale modification section determines a time scale modification speed depending on an amount of residual storage data which have not been read out from the buffer memory, and modifies time scale of the acoustic signal depending on the time scale modification speed.
