Prosody is a key area of linguistics that explores tonal and rhythmic variations in speech. In tonal languages such as Yemba, prosody plays a crucial role in distinguishing between words with different meanings or different grammatical forms. However, despite the large number of native speakers of this language in Cameroon, there are few resources for the speech recognition and synthesis. In this article, we present YembaTones, a syllabic and tonal annotated dataset, created from a dictionary we designed of 344 Yemba/French words coming from the most common phrases of the language, grouped according to their spellings that only differ by the tone...

PURPOSE: To cross-culturally adapt and validate the Radboud Dysarthria Assessment (RDA) and the speech component of the Radboud Oral Motor inventory for Parkinson's disease (ROMP-speech) into the Arabic language among Lebanese subjects with dysarthria. MATERIALS AND METHODS: This study included 50 participants with dysarthria. The Arabic versions of the RDA (A-RDA) and the ROMP-speech (A-ROMP-speech) were administered in addition to the Arabic Speech Intelligibility test, the Lebanese Voice Handicap Index-10 (VHI-10lb) and semantic verbal fluency tasks...

OBJECTIVES: Hoarseness is primarily perceived as breathiness or roughness. Despite the various tools that quantitatively assess hoarseness, roughness has been difficult to quantify because of its complex acoustic structure, such as subharmonics. The parameter obtained from the two-stage cepstral analysis is promising for evaluating roughness. Thus, this study aimed to improve the accuracy of the parameter using a customized pitch setting and investigate the relationship between roughness and subharmonics...

A total of 25 prelingually deaf children with profound deafness, who underwent cochlear implantation at the institute, were recruited from the outpatient department of the Department of Otorhinolaryngology...

OBJECTIVES: The aim of this study was to assess the prevalence of use of objective voice measurements (OVM), instrumentation, and factors that may impact OVM outcomes, such as setting and implementation to clarify current practice. Doing so should clarify the impact of OVM research on patient care. METHODS: A 12-question, one-time anonymous survey using the Research Electronic Data Capture tool was distributed during January 2023 to laryngologists in the United States identified through membership in The Voice Foundation (TVF) or previous participation in a TVF symposium...

Vocal fatigue is known as a hyperfunctional voice disorder that can lead to other conditions, such as muscle tension dysphonia (MTD). Speech and language pathologists (SLPs) are professional voice users who may suffer from vocal fatigue due to heavy vocal demands. This study aimed at investigating the cepstral and perceptual dimensions of voice and their correlation in the SLPs with vocal fatigue. Twenty-six SLPs and senior speech therapy students (mean age = 27.11 ± 6.8 yrs), including men (n = 5) and women (n = 21), participated in this descriptive cross-sectional study...

Voice assessment before and after treatment helps the clinician to assess the effectiveness of the treatment given and facilitates comparison between different treatment modalities. Voice handicap index -10(VHI-10) questionnaire is a tool which allows the voice to be evaluated subjectively from the patient's perspective. PRAAT is a freely available, software programme that acoustically analyse voice signals. Smart phones are widely used and the high quality of the embedded microphone in it makes it a suitable and easily available voice recording device...

In order to evaluate the effectiveness of the treatment in patients with functional dysphonia, the Cepstral Peak Prominence (CPP) test was used. Twenty dysphonic women aged from 18 to 47 years were under observation. The control group consisted of 20 healthy women of close age. Patients underwent 5-7 sessions electrostimulation of laryngeal muscles and phonopedic treatment, after which a complete restoration of the voice was noted. The Praat clinical program was used, installed on a Hewlett-Packard 630 laptop (Pentium B960, 2...

UNLABELLED: The voice of an individual is the result of interaction between the laryngeal and supra-laryngeal structures of a person. Since the laryngeal and supra-laryngeal structures differ from one person to another, the voice produced by each person becomes unique and recognizably different from another person. If this uniqueness in voice can be found in the acoustic parameters of the voice, it can contribute to the fields of forensic speaker identification and voice biometrics. The best methodology for such a study would be a comparison of the voices of twins who have a number of similar characteristics...

The available quantitative methods for evaluating bulbar dysfunction in patients with amyotrophic lateral sclerosis (ALS) are limited.
