Abstract

A sound signal generating method, a sound signal generating device, and a computer program where high quality sound in which sound quality deterioration such as a noise sensitivity or a surface roughness sensitivity is suppressed is generated by processing the original sound signal to generate the processed sound signal are provided. The processed sound signal is generated by separating the original sound signal in the pitch unit of a waveform to generate a plurality of unit waveform signals, generating a repetition waveform signal for repeating the waveform of the generated unit waveform signals by the number of predetermined times for each of the unit waveform signals, and moving each of the repetition waveform signals in the order in which the original sound signal is formed in the pitch unit and superposing on one another.

Description

technical field

[0001] The present invention relates to an audio signal generating method for generating a processed audio signal by processing an original audio signal, an audio signal generating device to which the audio signal generating method is applied, and a computer program for realizing the audio signal generating device. Background technique

[0002] In recent years, a function of reading text data of emails and website contents by voice has been installed in embedded devices such as cellular phones. In the speech synthesis processing for realizing such a speech reading function, the speech unit data required for synthesizing speech by compression methods such as ADPCM (Adaptive Differential Pulse Code Modulation, Adaptive Differential Pulse Code Modulation) are recorded in a recording unit such as a built-in memory in advance. The compressed and recorded database is the waveform library. In addition, when generating a synthesized speech waveform, the compressed s...
