20080215330 | Audio Signal Modification - A method of modifying an audio signal comprises the steps of analyzing the input audio signal (x) so as to produce a set of filter parameters (p) and a residual signal (r), modifying the set of filter parameters (p) so as to produce a modified set of filter parameters (p′), and synthesizing an output audio signal (y) using the modified set of filter parameters (p′) and the residual signal (r). The set of filter parameters (p) comprises poles (λ | 09-04-2008 |

20100235169 | SPEECH DIFFERENTIATION - Method for differentiation between voices including 1) analyzing perceptually relevant signal properties of the voices, e.g. average pitch and pitch variance, 2) determining sets of parameters representing the signal properties of the voices, and finally 3) extracting voice modification parameters representing modified signal properties of at least some of the voices. Hereby it is possible to increase a mutual parameter distance between the voices, and thereby the perceptual difference between the voices, when the voices have been modified according to the voice modification parameters. Preferably most of or all voices are modified in order to limit the amount of modification of one parameter. Preferred signal property measures are: pitch, pitch variance over time, glottal pulse shape, formant frequencies, signal amplitude, energy differences between voiced and un-voiced speech segments, characteristics related to overall spectrum contour of speech, characteristics related to dynamic variation of one or more measures in long speech segment. The method allows an automatic voice differentiation with a natural sound since it is based on a modification of signal properties determined for each of the voices. | 09-16-2010 |
