<p><P>PROBLEM TO BE SOLVED: To provide a voice information processing apparatus etc. capable of easily discriminating voice when a person breathes, from other voice. <P>SOLUTION: A Fourier transform section 204 performs Fourier transform of voice information received by an input receiving section 203 of the voice information processing apparatus 201. A determining section 205 determines that the voice information is breathing voice, if the following conditions continues to meet in more than a prescribed period, that in three frequency bands, there is at least one component whose intensity in a high frequency band is more than a first threshold value, and there are more components than the threshold number, whose intensity in a middle frequency band is more than the second threshold value, and there is at least one component whose intensity in a low frequency band is more than a third threshold value. A non-breathing voice output section 206 outputs the voice information in a period, which is not breathing voice period. <P>COPYRIGHT: (C)2007,JPO&INPIT</p> |
