OBJECTIVE Chronic cough (CC) and paradoxical vocal fold movement (PVFM) may be associated with voice problems. Objective acoustic and electroglottographic (EGG) measures have the capacity to delineate these vocal characteristics. This study investigated acoustic and EGG voice features of CC and PVFM. PATIENTS AND METHODS Acoustic and EGG findings were compared among 5 groups of participants. ...

In automatic speech recognition applications, due to significant differences in voice characteristics, adults and children are usually treated as two population groups, for which different acoustic models are trained. In this paper, age-independent acoustic modeling is investigated in the context of large vocabulary speech recognition. Exploiting a small amount (9 hours) of children’s speech an...

PURPOSE The purpose of this study was to examine relationships between prosodic speech cues and autism spectrum disorder (ASD) severity, hypothesizing a mutually interactive relationship between the speech characteristics of the psychologist and the child. The authors objectively quantified acoustic-prosodic cues of the psychologist and of the child with ASD during spontaneous interaction, esta...

Introduction: Benign vocal cord lesions cause significant dysphonia by disrupting the normal vibratory function of the vocal fold mucosa. Multidimensional assessment of voice characteristics allows for an accurate analysis of voice impairment and can be used to assess the outcome of different treatment modalities. Aims: To evaluate the outcome in patients treated for benign vocal fold lesions u...

   Objectives: The present study aimed at investigating the relationship between Dysphonia Severity Index (DSI) and disease speech and voice severity of Parkinson disease (PD) patients. Method. This study was a cross-sectional ones, carried out on 45 PD patients with the age range of 50 to 75 years, who were randomly selected. The Hoehn and Yahr Scale (H.Y Scale) was employed to measure the le...

The human voice provides a rich source of information about individual attributes such as body size, developmental stability and emotional state. Moreover, there is evidence that female voice characteristics change across the menstrual cycle. A previous study reported that women speak with higher fundamental frequency (F0) in the high-fertility compared to the low-fertility phase. To gain furth...

Voice registers are widely affected when voice diseases appear. These diseases have to be diagnosed and treated during an early stage. Detection of voice diseases may be carried out by means of acoustic analysis of voice register. Many algorithms to calculate acoustic parameters have been developed and have been demonstrated that there is a great correlation between parameter deviations and imp...

Pathology is the study and diagnosis of disease. Due to the nature of job, unhealthy habits and voice abuse, the people are subjected to the risk of voice problems. The diagnosis of vocal and voice disorders should be in the early stage otherwise it causes changes in the normal signal. It is well known that most of vocal fold pathologies cause changes in the acoustic voice signal. Therefore, th...

Over recent decades, much effort has been invested in the search for acoustic correlates of vocal function and dysfunction. The convenience of non-invasive voice measurements has been a major incentive for this effort. The acoustic signal is a rich but also very diversified source of information. Computer literacy and technical curiosity in the voice care and voice performance communities are n...
