A speaker conversion framework for formant synthesis is proposed. With this framework, given a small set of a target speaker’s utterances, segmental features of an original speech can be converted to those of the given speaker. Unlike other speaker conversion frameworks, further voice quality modification can also be applied to the converted speech with conventional formant modification techniq...

This paper describes an approach to the challenging problem of text and speaker independent voice conversion. The approach is based on target speaker’s speech production process parameterization using harmonic analysis. Unified model allows processing of any input speech regardless of its content and source speaker. The method provides subjective quality of conversion that is comparable with te...

The Internet has burgeoned into a worldwide information superhighway during the past few years, giving rise to a host of new applications and services. Among them, Voice over IP (VoIP) is the most prominent one. Beginning more as a frolic among computer enthusiasts, VoIP has set off a feeding frenzy in both the industrial and scientific communities and has the potential to radically change tele...

Voice conversion (VC) is an area of speech processing that deals with the conversion of the perceived speaker identity. In other words, the speech signal uttered by a first speaker, the source speaker, is modified to sound as if it was spoken by a second speaker, referred to as the target speaker. The most obvious use case for voice conversion is text-to-speech (TTS) synthesis where VC techniqu...

We present in this paper an exemplar-based Voice Conversion (VC) method using Non-negative Matrix Factorization (NMF), which is different from conventional statistical VC. NMF-based VC has advantages of noise robustness and naturalness of converted voice compared to Gaussian Mixture Model (GMM)based VC. However, because NMF-based VC is based on parallel training data of source and target speake...

Voice conversion aims to modify the characteristics of one speaker to make it sound like spoken by another speaker without changing the language content. This task has attracted considerable attention and various approaches have been proposed since two decades ago. The evaluation of voice conversion approaches, usually through time-intensive subject listening tests, requires a huge amount of hu...

evaluation of voice quality parameters of esophageal speech in different neoglottis forms after total laryngectomy. methods: presentation of voice analysis of 20 patients, who underwent total laryngectomy. the success of acquiring this technique was estimated by means of a voice analyzing program (pitch, sound-holding, loudness, spectrogram), and by the intelligibility via the telephone. shape ...
