Abstract:
1. A sensitivity enhancement apparatus to be connected to a chaos theoretical voice diagnosis apparatus for use as a preprocessing device, the sensitivity enhancement apparatus comprising: a voice input apparatus for acquiring an uttered voice; an analog-to-digital conversion apparatus for converting the acquired uttered voice to digital voice data; a comparator for selecting, from the digital voice data, voice data having a first level greater than or equal to a certain level, and for outputting the selected digital voice data; a voice data cutout apparatus capable of cutting out a phoneme unit of the selected digital voice data of a second level which is greater than or equal to the first level, and including an offset section for (i) providing a cutout start moment and a cutout end moment, according to which the cutout apparatus cuts out the phoneme unit and (ii) providing an offset value less than or equal to one phoneme; and a voice data output apparatus for outputting the phoneme unit cutout by the voice data cutout apparatus, wherein, when the cutout end moment is located at a middle of a phoneme of the phoneme unit cut out by the voice data cutout apparatus, the voice data cutout apparatus is operable to shift the cutout end moment to an end of the phoneme by shifting the cutout end moment by the offset value, and wherein, when the cutout start moment is located at a middle of a phoneme of the phoneme unit cut out by the voice data cutout apparatus, the voice data cutout apparatus is operable to shift the cutout start moment to a beginning of the phoneme by shifting the cutout start moment by the offset value.
