Voice quality is recognized to play an important role for the rendering of emotions in verbal communication. In this paper we explore the effectiveness of a processing framework for voice transformations finalized to the analysis and synthesis of emotive speech. We use a GMM-based model to compute the differences between an MBROLA voice and an anger voice, and we address the modification of the...

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...

We have more chances to communicate via the internet. We often use text/video chat, but there are some problems, such as a lack of communication and anonymity. In this paper, we propose and implement a real-time talking avatar, where we can communicate with each other by synchronizing character’s voice and motion from ours while keeping anonymity by using a voice conversion technique. For the v...

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...

This paper proposes a voice morphing system for people suffering from Laryngectomy, which is the surgical removal of all or part of the larynx or the voice box, particularly performed in cases of laryngeal cancer. A primitive method of achieving voice morphing is by extracting the source's vocal coefficients and then converting them into the target speaker's vocal parameters. In this ...

providing a high-quality service for transmission and playing real-time voice conversations (voice streaming) over wireless ad-hoc networks is no mean feat. buffering together with adjusting the playout time of the packets is a receiver-side solution to overcome this challenge. in this paper, a new adaptive playout adjustment algorithm is proposed to stream the voice conversations over wireless...

Dynamic Frequency Warping (DFW) offers an appealing alternative to GMM-based voice conversion, which suffers from ”over-smoothing” that hinders speech quality. However, to adjust spectral power after DFW, previous work returns to GMMtransformation. This paper proposes a more effective DFWwith amplitude scaling (DFWA) that functions on the acoustic class level and is independent of GMM-transform...

This paper describes a novel approach to flexible control of speaker characteristics using tensor representation of speaker space. In voice conversion studies, realization of conversion from/to an arbitrary speaker’s voice is one of the important objectives. For this purpose, eigenvoice conversion (EVC) based on an eigenvoice Gaussian mixture model (EV-GMM) was proposed. In the EVC, similarly t...

Voice conversion, as considered in this paper, is defined as modifying the speech signal of one speaker (source speaker) so that it sounds as if it had been pronounced by a different speaker (target speaker). Our contribution includes the design of a new methodology for representing the relationship between two sets of spectral envelopes. The proposed method is based on the use of a Gaussian mi...
