conclusions significant difference in the fundamental frequency, jitter, shimmer, silence duration, friction duration, vocalization duration, and vocal cords contact quality index between the two groups was observed (p < 0.01). results the mean of fundamental frequency for the hearing loss children and the control group were 323.04 hz and 267.53 hz, jitter 10.05% and 1.52%, shimmer 17.24 and 5....

PURPOSE To characterize the fundamental frequency and the frequency of the formants F1, F2, F3, and F4 from vocal emissions of amateur singers with metallic voice quality. METHODS There were 60 amateur female singers aged between 18 and 60 years old; 30 women with metallic voice quality forming the study group (SG) and 30 women without such a vocal quality forming control group (CG). The samp...

The categorization of voice into quality type (ie, normal, breathy, hoarse, rough) is often a traditional part of the voice diagnostic. The goal of this study was to assess the contributions of various time and spectral-based acoustic measures to the categorization of voice type for a diverse sample of voices collected from both functionally dysphonic (breathy, hoarse, and rough) (n=83) and nor...

. The present study deals with a voice quality that is referred to as “intelligible” or “articulate” voice. The purpose of the present study is to find a relation between the voice quality and acoustic features. The speech material is a read version of a simple short Japanese sentence “a o i so ra” in order to eliminate these linguistic variations. A set of speech samples uttered by fifteen adu...

We have developed a new text-to-speech system based on the VoiceFont technology. A VoiceFont is a voice dictionary for speech synthesis that holds the acoustic and prosodic characteristics extracted from the voice corpus of a speaker. The text-to-speech system using a VoiceFont is able to synthetically mimic the voice of the donor speaker. In this paper, we evaluated speaker recognizability of ...

Background Voice problems caused by pathologies in vocal folds are well known. Some types of laryngeal pathologies have certain acoustic characteristics. Objective evaluation helps characterize the voice and voice problems providing supporting evidences, severity of disorders. It helps assess the response to the treatment and measures the outcomes. Objective The objective of the study is to det...

Many studies were conducted on acoustic differences between female and male voices. However, they were generally led on speakers of only one language, and focused on a single acoustic parameter. The present study is an acoustic analysis of dissyllabic words or pseudo-words produced by Northeastern American English speakers and Parisian French speakers. Resonant frequencies, mean F0, F0 range, V...

This paper presents the concept of a voice profile as a complete description of the distributions of the acoustic correlates and the speaking characteristics of a speaker. A voice profile can be considered as a unified speakerdependent probability model of speech with applications in speaker identification, adaptive speech recognition, voice morphing and text to speech synthesis. The spectral a...

introduction: the every possible attempt in voice disorders assessment is to gather samples which represent individual s’ actual voice in the daily speech. the researchers have found that voice characteristics in reading a passage are closer to daily speech. making texts has been started since early 20th century. the lack o f suitable text in farsi language makes it difficult to conduct requisi...
