摘要： A voice converting apparatus is constructed for converting an input voice into an output voice according to a target voice. In the apparatus, a storage section provisionally stores source data, which is associated to and extracted from the target voice. An analyzing section analyzes the input voice to extract therefrom a series of input data frames representing the input voice. A producing section produces a series of target data frames representing the target voice based on the source data, while aligning the target data frames with the input data frames to secure synchronization between the target data frames and the input data frames. A synthesizing section synthesizes the output voice according to the target data frames and the input data frames. In the recognizing feature analysis, a characteristic analyzer extracts from the input voice a characteristic vector. A memory memorizes target behavior data representing a behavior of the target voice. An alignment processor determines a temporal relation between the input data frames and the target data frames according to the characteristic vector and the target behavior data so as to output alignment data. A target decoder produces the target data frames according to the alignment data, the input data frames and the source data containing phoneme of the target voice.

摘要： A singing voice synthesizing apparatus is provided, which enables achievement of a natural sounding synthesized singing voice with a good level of comprehensibility. A phoneme database stores a plurality of voice fragment data formed of voice fragments each being a single phoneme or a phoneme chain of at least two concatenated phonemes, each of the plurality of voice fragment data comprising data of a deterministic component and data of a stochastic component. A readout device that reads out from the phoneme database the voice fragment data corresponding to inputted lyrics. A duration time adjusting device adjusts time duration of the read-out voice fragment data so as to match a desired tempo and manner of singing. An adjusting device adjusts the deterministic component and the stochastic component of the read-out voice fragment so as to match a desired pitch. A synthesizing device synthesizes a singing sound by sequentially concatenating the voice fragment data that have been adjusted by the duration time adjusting device and the adjusting device.

摘要： A voice converter synthesizes an output voice signal from an input voice signal and a reference voice signal. In the voice converter, an analyzer device analyzes a plurality of sinusoidal wave components contained in the input voice signal to derive a parameter set of an original frequency and an original amplitude representing each sinusoidal wave component. A source device provides reference information characteristic of the reference voice signal. A modulator device modulates the parameter set of each sinusoidal wave component according to the reference information. A regenerator device operates according to each of the parameter sets as modulated to regenerate each of the sinusoidal wave components so that at least one of the frequency and the amplitude of each sinusoidal wave component as regenerated varies from original one, and mixes the regenerated sinusoidal wave components altogether to synthesize the output voice signal.

摘要： Analysis data are provided which are indicative of plural components making up an original sound waveform. The analysis data are analyzed to obtain a characteristic concerning a predetermined element, and then data indicative of the obtained characteristic is extracted as a sound or musical parameter. The characteristic corresponding to the extracted musical parameter is removed from the analysis data, and the original sound waveform is represented by a combination of the thus-modified analysis data and the musical parameter. These data are stored in a memory. The user can variably control the musical parameter. A characteristic corresponding to the controlled musical parameter is added to the analysis data. In this manner, a sound waveform is synthesized on the basis of the analysis data to which the controlled characteristic has been added. In such a sound synthesis technique of the analysis type, it is allowed to apply free controls to various sound elements such as a formant and a vibrato.

摘要： A musical sound analyzer and synthesizer uses a model that considers a sound to be composed of two types of elements: a deterministic component plus a stochastic component. The deterministic component is represented as a series of sinusoids, with an amplitude and a frequency function for each sinusoid. The stochastic component is represented as a series of magnitude spectral envelopes. From this representation, sounds can be synthesized that, in the absence of modifications, can behave as perceptual identities, that is, they are perceptually equal to the original sound. In addition, stored representations of sounds can be easily modified in a musical synthesizer to create a wide variety of new sounds.
