Through, acoustic analysis of crying, results of a primary palatoplasty can be evaluated in patients with cleft palate before development of speech, is objective, non-invasive, quick and simple tool for vocal exploration. The present study demonstrated that 46,XX CAH individuals, even when submitted to hormone therapy, present rough, low, deviant voice.Ĭrying in newborns and infants is a functional expression of biological interest.

No statistically significant difference was observed in the other acoustic parameters investigated (p>0.05). There were statistically significant differences between the groups only for the following vocal attributes of the CAPE-V: overall severity (p=0.01), roughness (p=0.00), and pitch (p=0.01). In the qualitative assessment of pitch, eight (61.54%) patients in the CAH group showed low vocal pattern and eight (61.54%) individuals in the group without CAH presented high vocal pattern. Acoustic (PRAAT program) and auditory-perceptual (Consensus Auditory-Perceptual Evaluation of Voice - CAPE-V) analyses were conducted.

Voice sample collection was performed individually in a quiet environment with participants properly seated. The study sample consisted of 28 volunteers: 14 individuals diagnosed with CAH, followed up by the multiprofessional team of the GOC-UFBA, and 14 46,XX individuals without vocal changes and endocrine and/or genetic pathologies. This is a descriptive, exploratory, cross-sectional study. Speech programs provide similar results in the acoustic analysis of pathological voices.ĭescribe the vocal profile of 46,XX congenital adrenal hyperplasia (CAH) patients followed up at the Genetics Outpatient Clinic of the Federal University Bahia (GOC-UFBA). The results indicated that the sound spectrogram and the numerical values obtained for shimmer and jitter were similar for both computer programs, even though types 1, 2 and 3 voice samples were analysed. As a final result, the acoustic parameters of jitter, shimmer, harmonics-to-noise ratio and fundamental frequency were obtained from the 2 acoustic analysis programs. They then determined the presence of noise in the spectrogram, using the Yanagihara grades, as well as the presence of subharmonics. The spectrographic analysis consisted of obtaining a narrow-band spectrogram from the previous digitalised voice samples by the 2 independent observers. Speech 3.0 and a second one used the Praat program (Phonetic Sciences, University of Amsterdam). We studied a total of 99 voice samples from individuals with Reinke's oedema diagnosed using videostroboscopy. Voice acoustic parameters (jitter, shimmer, harmonics-to-noise ratio, fundamental frequency) (quantitative). Narrow-band spectrogram (the presence of noise according to Yanagihara, and the presence of subharmonics) (semi-quantitative).

Praat program software#

Speech and the free software Praat in 2 fields: 1. The purpose of the present study was to correlate the results obtained by the commercial software Dr. In this study we focused on acoustic voice analysis.

The European Laryngological Society (ELS) basic protocol for functional assessment of voice pathology includes 5 different approaches: perception, videostroboscopy, acoustics, aerodynamics and subjective rating by the patient.
