OBJECTIVES To evaluate the applicability and effectiveness of percutaneous corticosteroid injection in patients with vocal fold polyp and to describe its advantages and limitations in this group of patients. DESIGN Prospective case series. SETTING Tertiary care teaching hospital. PATIENTS Twenty-four patients with vocal fold polyp treated between March 1 and December 31, 2007. INTERVENT...

CONTEXT Speech abnormalities are common to the three Parkinsonian syndromes, namely Parkinson's disease (PD), progressive supranuclear palsy (PSP) and multiple system atrophy (MSA), the nature and severity of which is of clinical interest and diagnostic value. AIM To evaluate the clinical pattern of speech impairment in patients with PD, PSP and MSA and to identify significant differences on ...

Despite the growing number of studies on the acoustics of non-modal phonation, little is known about how two distinct non-modal phonations can interact acoustically when coarticulated. This study investigates the acoustics of breathy-to-creaky phonation contours in vowels from a production study of native speakers of English and White Hmong. These languages differ in the nature of the non-modal...

Objectives: Biofeedback therapy is a training technique that has positive effect on the voice. In order to conduct resonant voice or tube phonation more effectively, it important for patient feel vibration sensation in specific part of facial structures. Therefore, this study, clinical basis was presented by quantifying site and magnitude using sensors during various semi-occluded vocal tract p...

PURPOSE The supracricoid laryngectomies (SCLs) are conservative surgical techniques for the treatment of selected laryngeal carcinomas. The advantage of SCL is that a permanent tracheostoma is not required, thus, maintaining the principal laryngeal functions. The aim of the study is to report objective, subjective, and self-assessment long-term results of voice and swallowing in a large group o...

OBJECTIVE Supraglottic laryngectomy is a surgical procedure that preserves laryngeal functions. This technique allows extensions including removal of tongue base or 1 arytenoid. We aimed to compare vocal results of supraglottic laryngectomy and extended procedures. STUDY DESIGN Cross-sectional study. SETTING Tertiary care hospital. SUBJECTS AND METHODS Thirty-three males who underwent sup...

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...

This paper presents a design for two novel methods of speech fundamental frequency (f0) detection in pathological voices. The methods are tested on the database of vowelsustained phonation. One method is based on the detection of maxima and the other on signal filtration with band pass. Compared to other well known f0 detection methods, our algorithms are designed with respect to speech patholo...

Languages where phonation type and tone are contrastive make use of extremely fine and controlled actions of laryngeal structures; hence, there is little opportunity to variation in either phonation or pitch. Nonetheless, many American Indian languages have contrastive nonmodal phonation, which, moreover, is subject to a great deal of variation. There are a few studies addressing the phonetics ...

The term voice quality or phonation types often come from studies of pathological speech. In normal speech speakers use different phonation types in some languages for linguistic distinction, prosodically as a boundary signal and in attitudes and emotions. Our paper aims to describe the different phonation types that occur in Standard Chinese TV newscasts and the relationship between creaky voi...
