Control over voice quality, e.g. breathy and tense voice, is important for speech synthesis applications. For example, transformations can be used to modify aspects of the voice related to speaker’s identity and to improve expressiveness. However, it is hard to modify voice characteristics of the synthetic speech, without degrading speech quality. State-of-the-art statistical speech synthesiser...

In this work, we propose a peer-to-peer (P2P) voice delivery architecture for the support of an immersive communication environment (ICE). An ICE service allows multiple users in a distributed virtual environment (DVE) to exchange live voices which are rendered with the directional and distance cues corresponding to the users' positions in the DVE. Our architecture addresses the scalability iss...

Voice communication is an emerging technology and has great importance in our routine life. Perceptual, Voice over Internet Protocol quality is an important issue for VoIP Apps services because VoIP Apps require real-time support. Many network factors (packet loss, packet delay, and jitter) affect to VoIP quality, to achieve this objective we used an approach based on Fuzzy Logic. We configure ...

One of the most important human abilities is speech along with hearing. Speech is the primary way in which we attune to the society. Our voice can uncover several information about us to other people. It reveals our energy level, our emotions, our personality and our artistry. Voice abnormalities may cause social isolation or may create problems in the professional field. Due to this significan...

This paper reviews our proposed approach to voice conversion (VC) and voice quality control based on an eigenvoice technique. VC is a technique to modify nonlinguistic information such as speaker individuality while keeping linguistic information unchanged. In the traditional VC framework, a conversion model for a source and target speaker-pair needs to be trained in advance using a parallel da...

The present study aimed at presenting the instructional material developed in the Brazilian Portuguese context to apply the Voice Profile Analysis Scheme-VPAS (PB-VPAS) for the perceptual evaluation of voice quality and at reporting preliminary data analyzed from a group of six judges who attended a workshop on VPAS. The adaptation of the VPAS into Brazilian Portuguese was accomplished and the ...

Internet telephony has had a tremendous impact on how people communicate. Many now maintain contact using some form of Internet telephony. Therefore the motivation for this work has been to address the quality aspects of real-world Internet telephony for both fixed and wireless telecommunication. The focus has been on the quality aspects of voice communication, since poor quality leads often to...

OBJECTIVE To validate the Pediatric Voice-Related Quality-of-Life (PVRQOL) survey, which was designed to assess voice changes over time in the pediatric population. DESIGN Prospective longitudinal study. SETTING Outpatient pediatric otolaryngology office practice. PARTICIPANTS One hundred twenty parents of children aged 2 through 18 years having a variety of otolaryngological diagnoses in...

BACKGROUND Supracricoid partial laryngectomy (SCPL) results in laryngeal preservation in more than 95% of patients with T2 glottic carcinoma. Postsurgical glottic function is characterized by an absence of vocal cords, and phonation quality is a key post-SCPL quality-of-life factor. OBJECTIVE This investigation was designed to enhance post-SCPL vocal function, study anatomic function of the p...

Introduction: Essential vocal tremor (EVT) is vocal tremor occurring in an individual diagnosed with essential tremor and is an action induced tremor that occurs during speech production. It causes fewer communication attempts, difficulty initiating and maintaining phonation, effortful speaking avoidance of social events trouble sustaining relationship leading to impair quality of life for such...
