Singing Voice Synthesis: Singer-Dependent Vibrato Modeling and Coherent Processing of Spectral Envelope
نویسندگان
چکیده
Pleasant singing voice is often ornamented by vibrato. This pitch fluctuation acts as a distinctive feature for singing and promotes voice quality. Nevertheless, independent pitch processing in singing voice synthesis does not guarantee the output quality. The spectral envelope actually varies with pitch during human voice production. This paper proposes a modeling technique for singers’ vibratos, followed by a joint processing on vibrato and spectral envelope, such that these attributes are consistent. The performance of the proposed processing has been verified by subjective listening test. The synthetic singing outputs are found to have similar quality as the human singing.

Vibrato in Singing Voice: The Link between Source-Filter and Sinusoidal Models
The application of inverse filtering techniques for high-quality singing voice analysis/synthesis is discussed. In the context of source-filter models, inverse filtering provides a noninvasive method to extract the voice source, and thus to study voice quality. Although this approach is widely used in speech synthesis, this is not the case in singing voice. Several studies have proved that inve...
متن کاملSpeech-to-Singing Synthesis System: Vocal Conversion from Speaking Voices to Singing Voices by Controlling Acoustic Features Unique to Singing Voices
Introduction: This paper introduces a speech-to-singing synthesis system, called SingBySpeaking, which can synthesize a singing voice, given a speaking voice reading the lyrics of a song and its musical score. The system is based on the speech manipulation system STRAIGHT and is comprised of four models controlling three acoustic parameters: the fundamental frequency (F0), phoneme duration, and...
متن کاملA Study of Vibrato Features to Control Singing Voices
Singing synthesis applications have recently been developed to create natural singing voices. Applications such as VOCALOID can synthesize singing voices by inputting lyrics and scores, and musical expressions such as vibrato and portamento are added to the singing voices by controlling pitches. This control is crucial to synthesize natural singing voices, but users are required to edit the pit...
متن کاملSinging Synthesis Using Ann Vibrato Model
Vibrato is an important factor that affects the naturalness level of a synthetic singing voice. Therefore, the analysis and modeling of vibrato parameters are studied in this paper. The vibrato parameters of those syllables segmented from recorded songs are analyzed by using short-time Fourier transform and the method of analytic signal. After the vibrato parameter values for all training sylla...
متن کاملVocal conversion from speaking voice to singing voice using STRAIGHT
A vocal conversion system that can synthesize a singing voice given a speaking voice and a musical score is proposed. It is based on the speech manipulation system STRAIGHT [1], and comprises three models controlling three acoustic features unique to singing voices: the F0, duration, and spectral envelope. Given the musical score and its tempo, the F0 control model generates the F0 contour of t...
