Voice Conversion Using Pitch Shifting Algorithm by Time Stretching with Psola and Re–sampling
Voice changing has many applications in the industry and commercial filed. This paper emphasizes voice conversion using a pitch shifting method which depends on detecting the pitch of the signal (fundamental frequency) using Simplified Inverse Filter Tracking (SIFT) and changing it according to the target pitch period using time stretching with Pitch Synchronous Over Lap Add Algorithm (PSOLA), ...
متن کاملImproved Pvsola Time-stretching and Pitch-shifting for Polyphonic Audio
An advanced phase vocoder technique for high quality audio pitch shifting and time stretching is described. Its main concept is based on the PVSOLA time stretching algorithm which is already known to give good results on monophonic speech. Some enhancements are proposed to add the ability to process polyphonic material at equal quality by distinguishing between sinusoidal and noisy frequency co...
متن کاملTime Stretching & Pitch Shifting with the Web Audio API: Where are we at?
Audio time stretching and pitch shifting are operations that all major commercial and/or open source Digital Audio Workstations, DJ Mixing Software and Live Coding Suites offer. These operations allow users to change the duration of audio files while maintaining the pitch and vice-versa. Such operations enable DJs to speed up or slow down songs in order to mix them by aligning the beats. Unfort...
متن کاملWaveform Preserving Time Stretching and Pitch Shifting for Sinusoidal Models of Sound
A method for performing waveform invariant time stretching and pitch shifting on a quasi harmonic and sinusoidally modeled sound is presented. The method is based on the relative phase delay representation of the phase, defined as the difference between the phase delay of the partials and the phase delay of the fundamental. This representation makes the waveform characterization independent fro...
متن کاملTransforming Pitch in a Voice Conversion Framework
A subtask of voice conversion is to accurately map the pitch contour of a source speaker to a target speaker. So far, the most widely employed method for carrying out this mapping is based on adjusting the pitch range of the source speaker to match the target while keeping the shape of the contour unchanged. In this project, we investigate four alternative algorithms for pitch contour mapping a...
