Pitch Track Target Deviation in Natural Singing
نویسنده
چکیده
Unlike fixed-pitch instruments such as the piano, human singing can stray from a target pitch by as much as a semitone while still being perceived as a single fixed note. This paper presents a study of the difference between target pitch and actualized pitch in natural singing. A set of 50 subjects singing the same melody and lyric is used to compare utterance styles. An algorithm for alignment of idealized template pitch tracks to measured frequency tracks is presented. Specific examples are discussed, and generalizations are made with respect to the types of deviations typical in human singing. Demographics, including the skill of the singer, are presented and discussed in the context of the pitch track deviation from the ideal.

The Humanisation of Stochastic Processes for the Modelling of F0 Drift in Singing
We present a model for the generation of low frequency human-like pitch deviation. We take f0 measurements from vocalists producing a 300Hz fixed tone without vibrato and find that smaller regions are evident, each with QuasiGaussian distributions. We present a function to implement this with a PSOLA pitch shifting algorithm, providing natural sounding enhancements to singing voice synthesis sy...
متن کاملTowards a Model for the Humanisation of Pitch Drift in Singing Voice Synthesis
A model is presented for the analysis and synthesis of low frequency human-like pitch deviation, as a replacement for existing modulation techniques in singing voice synthesis systems. We build on research taken from [1], in order to find the features of drift under selected conditions in singing. Fundamental Frequency ( f0) measurements are taken from vocalists producing a selected range of ut...
متن کاملDevelopment of Voice Pitch Control System Using Two Dimensional Tactile Display for the Deafblind or the Hearing Impaired Persons
Deafblind or the hearing impaired persons have great difficulty with controlling their voice pitch because they cannot perceive own voice. In particular, when singing it is very difficult for them to control their voice pitch because they need take effort to maintain a stable tone. In this research, a voice pitch control system was developed to assist their singing by means of a two dimensional...
متن کاملSinging proficiency in the majority: normality and "phenotypes" of poor singing.
Recent evidence indicates that the majority of occasional singers can carry a tune. For example, when asked to sing a well-known song (e.g., "Happy Birthday"), nonmusicians performing at a slow tempo are as proficient as professional singers. Yet, some occasional singers are poor singers, mostly in the pitch domain, and sometimes despite not having impoverished perception. Poor singing is not a...
متن کاملSinging with yourself: evidence for an inverse modeling account of poor-pitch singing.
Singing is a ubiquitous and culturally significant activity that humans engage in from an early age. Nevertheless, some individuals - termed poor-pitch singers - are unable to match target pitches within a musical semitone while singing. In the experiments reported here, we tested whether poor-pitch singing deficits would be reduced when individuals imitate recordings of themselves as opposed t...
