reports indicate that one of the causes of harmful to the genital system, especially the testes is stress. result of damage to testicular quality certainly will affect the quality of sperm fertility. stress could be created secondarily after some pathological conditions such as neurological diseases or environmental factors. one of the causes of stress could be scary voices, such as cat voice f...

Physical modeling of the phonatory and vocal tract systems has served as a useful tool to study many aspects of speech production. This paper offers a brief review of two specific types of physically-based models. One for simulating the vibration of the vocal folds and another for representing the vocal tract shape in the form of an area function. While much of the technical detail of these mod...

Voice quality assessment is an emergent aspect in Global System for Mobile Communications (GSM) network. The evolution of GSM also able in principle to take benefit from end to end services.GSM network inherently include elements such as noisy intermediate equipments that degrade the quality of transmitted voice signal.GSM network presents an alternate method to improve quality and customer exp...

Introduction: Surgical procedures, especially total laryngectomy, have a profound adverse effect on the patient's physical, functional, as well as emotional health, and strongly decrease quality of life. Tracheoesophageal puncture is one of the most significant method that is widely performed successfully by physicians. Current valve technology enables long expiring duration; however, gen...

This paper explores the role of voice quality in the communication of emotions, moods and attitudes. Listeners reactions to an utterance synthesised with seven different voice qualities were elicited in terms of pairs of opposing affective attributes. The voice qualities included harsh voice, tense voice, modal voice, breathy voice, whispery voice, creaky voice and lax–creaky voice. These were ...

Glaswegian vernacular is well known for a stereotypical ‘Glasgow voice’, with slack articulation, jaw protrusion, and harsh phonation. The extent to which speakers of Glaswegian really exhibit such features of voice quality remains largely anecdotal. Indeed, bar a few notable exceptions, voice quality has been largely neglected in accounts of regional and social accents of Britain. This paper p...

This paper describes a technique for controlling voice quality of synthetic speech using multiple regression hidden semi-Markov model (HSMM). In the technique, we assume that the mean vectors of output and state duration distribution of HSMM are modeled by multiple regression with a parameter vector called voice quality control vector. We first choose three features for controlling voice qualit...

Voice quality is currently a key issue in speech synthesis research. The lack of realistic intra-speaker voice quality variation is an important source of concern for concatenation-based synthesis methods. A challenging problem is to reproduce the voice quality changes that are occuring in natural speech when the vocal e ort is varying. A new method for voice quality modi cation is presented. I...

This study compared the voice quality of high and low falling unchecked and checked tones. Spectral tilt measured as H0A2 was taken from the syllable midpoint of second, third and four syllables in SVO sentences. Results showed that the voice quality of checked tones was not always creakier than unchecked tones. The voice quality of a syllable at the end of an utterance was not creakier than a ...
