1. A performance apparatus comprising:
- a plurality of key switches disposed in a predetermined arrangement;
a memory that stores a plurality of tone data corresponding to the key switches;
a controller that samples an audio signal containing phonemes for a predetermined period, detects breaks between the phonemes contained in the sampled audio data, extracts a plurality of random sections, each containing a phoneme, from the sampled audio signal, detects the frequencies of the extracted random sections of tone data and associates the extracted random sections to the plurality of key switches in order of the frequencies, and writes the extracted plurality of random sections as the plurality of tone data into said memory;
a tone generation section that audibly sounds any one of the tones corresponding to the stored tone data with a corresponding designated one of the key switches,wherein each of the random sections is extracted from a start position of the respective phoneme for a predetermined length.

Abstract
A plurality of key switches are disposed in a predetermined arrangement, such as a matrix arrangement, and a tone generator includes a memory for storing tone (waveform) data corresponding to the key switches. Sampling section acquires an audio signal from an external source, cuts out tone data from the acquired audio signal and writes the cut-out tone data into the memory in association with the key switches. Any one of the key switches is designated on the basis of switch operation by a user or on the basis of automatic performance information, so that, of the tone data stored in the memory, the tone data corresponding to the designated key switch is sounded, i.e. audibly reproduced.

10. A method of generating audible sounds with a performance apparatus that includes a plurality of key switches disposed in a predetermined arrangement, a memory that stores a plurality of tone data corresponding to the key switches, and a tone generation section that audibly sounds any one of the tones corresponding to the stored tone data with a designated one of the key switches, said method comprising the steps of:
-
sampling an audio signal containing phonemes for a predetermined period; detecting breaks between the phonemes contained in the sampled audio data; extracting a plurality of random sections, each containing a phoneme, from the sampled audio signal, wherein each of the random sections is extracted from a start position of the respective phoneme for a predetermined length; detecting the frequencies of the extracted random sections and associating the extracted random sections to the plurality of key switches in order of the frequencies; writing the extracted plurality of random sections as the plurality of tone data into said memory; and audibly sounding via said tone generation section any one of the tones corresponding to the stored tone data with the corresponding designated key switch.

11. A computer-readable medium storing a computer program for controlling a performance apparatus to generate audible sounds, said performance apparatus including a plurality of key switches disposed in a predetermined arrangement, a memory that stores a plurality of tone data corresponding to the key switches, and a tone generation section that audibly sounds any one of the stored tone data with a designated one of the key switches, the program including instructions for:
-
sampling an audio signal containing phonemes for a predetermined period; detecting breaks between the phonemes contained in the sampled audio data; extracting a plurality of random sections, each containing a phoneme, from the sampled audio signal, wherein each of the random sections is extracted from a start position of the respective phoneme for a predetermined length; detecting the frequencies of the extracted random sections and associating the extracted random sections to the plurality of key switches in order of the frequencies; writing the extracted plurality of random sections as the plurality of tone data into said memory; and audibly sounding via said tone generation section any one of the tones corresponding to the stored tone data with the corresponding designated key switch.
