“…Hirano developed it in 1981 to evaluate the severity of dysphonia and the type of voice quality. The Hirano GRBAS scale which is examinerbased is the gold standard in perceptual analysis of voice (Jesus et al, 2017) and considers the severity of a vocal disorder along a scale divided into regular intervals. The GRBAS scale is valid and reliable and provides no discomfort or inconvenience to both the patient and a therapist.…”

Adenoids and tonsils are pharyngeal lymphoid tissue aggregation. Adenotonsillar hypertrophy is usually seen in children. Enlarged adenoid and tonsillar tissue in children causes snoring, sleeping disorders, failure to thrive, frequent upper respiratory tract infections and abnormalities in maxillofacial development. Surgical treatment performed for their removal is termed as adenotonsillectomy. This is one of the most commonly performed surgical procedures in children. The present study was conducted to compare the voice change using the GRBAS scale before and after adenotonsillectomy. This is a prospective study conducted for three months at the Department of Otorhinolaryngology in our tertiary care center. Voice of 35 children with adenotonsillar hypertrophy is analyzed by GRBAS scale in three stages before the surgery, three weeks after surgery and six weeks after surgery. The resulting voice quality improvement is noted in these children after adenotonsillectomy. This study showed that surgical procedures of adenotonsillectomy do not induce drastic adjustments in sound quality and can be performed safely in children. Post-operative voice changes are a significant concern issue among the parents of the children.

“…Reference acoustic databases allow the standardization of acoustic analysis, benchmarking and comparing the performance of different voice analysis techniques. They also allow to differentiate normal voice and pathological voice, to evaluate and monitor it clinically, and to diminish the subjectivity that underlies the acoustic-perceptual analysis [22] by establishing a correlation between quantitative data. Results can be interpreted reliably, as long as they are collected by the same equipment, and the same data collection methods and recording techniques are used [43].…”

A new open access resource called Advanced Voice Function Assessment Databases (AVFAD) was developed, based on a sample of 709 individuals (346 clinically diagnosed with vocal pathology and 363 with no vocal alterations) recruited in Portugal. All clinical conditions were registered according to the Classification Manual of Voice Disorders-I. Participants were audio-recorded, producing the following vocal tasks: Sustaining vowels /a, i, u/; reading of six CAPE-V sentences; reading a phonetically balanced text; spontaneous speech. The AVFAD are comprised of 8648 uncompressed audio files and an additional database file with 19 Praat Voice Report parameter values and 16 clinical data entries per participant. An annotated segment of the vowel /a/ for each participant was analysed automatically with a Praat script. Radial graphs were generated considering that all variables had an approximately normal distribution, and using previously calculated average and standard deviation values for all parameters. The normal and pathological f0 mean, Jitter ppq5, Shimmer apq11 and Harmonics-to-Noise-Ratio characteristics were compared. An additional analysis of the relation between the acoustic parameters and gender, age group, smoking habits, body mass index and voice usage, was considered. The AVFAD will allow future cooperative work and testing of non-invasive methods for voice pathology diagnosis.
