Objective analysis of the singing voice as related to singer posture
نویسندگان
چکیده
This paper deals with objective analysis of the singing voice, and aims at giving non-professional singers both an aid to improve their voice capabilities and a criterion to prevent a wrong vocal attitude (head, neck, and body posture) that could even cause vocal pathologies. A new standalone application with a user-friendly interface is proposed, for robust and reliable analysis of singing voice characteristics. The tool performs tracking of fundamental frequency and formants, along with an objective measure of main singing voice parameters, such as vibrato rate (V_rate), vibrato extent (V_ext), and vocal intonation (V_int). A sideview camera allows displaying and recording the singer’s posture. Data are collected at the School of Music in Fiesole, Firenze, Italy, under the supervision of a voice teacher and a teacher of Alexander Technique (AT). First results are presented to compare some vocalizations coming both from professional and non-professional singers under different singer’s postures.

Statistical singing voice conversion with direct waveform modification based on the spectrum differential
This paper presents a novel statistical singing voice conversion (SVC) technique with direct waveform modification based on the spectrum differential that can convert voice timbre of a source singer into that of a target singer without using a vocoder to generate converted singing voice waveforms. SVC makes it possible to convert singing voice characteristics of an arbitrary source singer into ...
متن کاملEvaluation of a singing voice conversion method based on many-to-many eigenvoice conversion
In this paper, we evaluate our proposed singing voice conversion method from various perspectives. To enable singers to freely control their voice timbre of singing voice, we have proposed a singing voice conversion method based on many-tomany eigenvoice conversion (EVC) that enables to convert the voice timbre of an arbitrary source singer into that of another arbitrary target singer using a p...
متن کاملAn investigation of acoustic features for singing voice conversion based on perceptual age
In this paper, we investigate the acoustic features that can be modified to control the perceptual age of a singing voice. Singers can sing expressively by controlling prosody and vocal timbre, but the varieties of voices that singers can produce are limited by physical constraints. Previous work has attempted to overcome this limitation through the use of statistical voice conversion. This tec...
متن کاملStatistical singing voice conversion based on direct waveform modification with global variance
This paper presents techniques to improve the quality of voices generated through statistical singing voice conversion with direct waveform modification based on spectrum differential (DIFFSVC). The DIFFSVC method makes it possible to convert singing voice characteristics of a source singer into those of a target singer without using vocoder-based waveform generation. However, quality of the co...
متن کاملImprovements of Voice Timbre Control Based on Perceived Age in Singing Voice Conversion
As one of the techniques enabling individual singers to produce the varieties of voice timbre beyond their own physical constraints, a statistical voice timbre control technique based on the perceived age has been developed. In this technique, the perceived age of a singing voice, which is the age of the singer as perceived by the listener, is used as one of the intuitively understandable measu...
