Introduction. There are subjective and objective ways to examine the effects of vocal therapy in voice disorders. The most precise and objective check-up is the use of computer voice analysis. Objective. The aim of the research was to perform a detailed analysis of acoustic structure of the vowel A before and after voice treatment in patients with vocal fold nodules in order to obtain objective verification of the vocal rehabilitation success. Methods. We examined 30 female patients, aged 34.6?6.69 years, with vocal fold nodules. Acoustic parameters of voice were compared with the control group consisting of 21 subjects without voice pathology. In all persons the vowel A was recorded and analyzed before and after a month of vocal therapy. The success of the vocal therapy was tracked using computer analysis of vocal structure. Signal, noise and tremor parameters were processed. Results. Of the analyzed vowel A parameters: STD, PER, JITA, JITT, RAP, vFO, ShdB, SHIM, APQ, VTI, SPI, F0, NHR, FTRI, eleven improved (p<0.05 and p<0.01). Three parameters (F0, NHR, FTRI) changed showing improvement, but the obtained differences were not statistically significant (p>0.05). Conclusion. Based on the obtained results it was concluded that vocal therapy gave satisfactory results, but that it should be continually applied until full stabilization of the voice.

The article is devoted to the influence of pharyngolaryngeal reflux on the voice acoustic parameters in patients before and after the antireflux surgery (fundoplication). The study involved 12 patients aged 33 to 64 years with a confirmed impedance–pH monitoring diagnosis of gastroesophageal reflux disease. The control group included 10 patients aged 18 to 33 years. These subjects did not have any upper respiratory diseases (including pharyngolaryngeal reflux) and gastrointestinal tract diseases. Computer voice analysis was used to objectively evaluate the voice acoustic parameters. In patients before fundoplication, a statistically significant increase in Jitter and Shimmer parameters was observed in 100% of cases compared with the control group (p ≤ 0,05). In the late postoperative period, 6 months after surgery, the analysis of acoustic parameters of voice in the study group revealed: Jitter and Shimmer indicators in 100% of cases significantly decreased compared to the preoperative values (p ≤ 0,05), which indicates an improvement in voice function. Jitter and Shimmer were the most diagnostically significant parameters.

PURPOSE: To investigate laryngeal and voice disorders in patients with gastroesophageal symptoms and their correlation with pH-monitoring. METHODS: A prospective study was carried out in patients attended at the Voice Disorder Outpatient Clinics of Botucatu Medical School in a five-year period and had vocal and gastroesophagic symptoms. Patients underwent videolaryngoscopy, auditory-perceptual vocal analyses, computerized acoustic vocal analysis and dual probe pH-monitoring for 24 hours. RESULTS: Fifty-seven patients were included (aged between 21 and 65 years; 45 women and 12 men), 18 had normal (31.6%) and 39 had abnormal pH-monitoring results (68.4%). Videolaryngoscopy recorded several laryngeal lesions for both patients with normal and abnormal pH-monitoring, but mostly for the latter group, highlighting posterior pachyderma. Auditory-perceptual vocal assessments identified vocal changes of several intensities for both groups but especially for patients with abnormal pH-monitoring results. All acoustic parameters, except f0, were abnormal for both groups, compared to the control population. CONCLUSION: Acoustic and perceptual vocal changes and laryngeal lesions were recorded for both patients with normal pH-monitoring results and patients with abnormal pH-monitoring results, evidencing the importance of clinical history and videolaryngoscopic findings for diagnosing acid laryngitis.

The goal of this study was to determine which acoustic parameters are significant in differentiating the speaking styles of a narrator and that of male and female characters as voiced by a reader of audiobooks. The study was initiated by a need to improve the expressivity and differentiation of speaking styles in fiction books read out by synthesized voices. The corpus used as research material was created from an audio novel, as read by a professional male voice artist. To determine whether it is possible to identify these speaking styles from the voice of the reader, a web-based perception test consisting of 48 sentences was conducted. The results showed that the listeners identified all three styles. For acoustic analysis, the openSMILE toolkit was used and 88 eGeMAPS-defined parameters were extracted for every sentence in the corpus. All styles were differentiated by 38 statistically significant parameters. To improve vividness, synthesizers aimed at reading fiction books could be trained to perform all three styles. Kokkuvõte. Hille Pajupuu, Rene Altrov ja Jaan Pajupuu: Teel audioraamatute sünteeskõne elavdamisele. Uurimuse eesmärk oli teada saada, milli sed olulisemad akustilised parameetrid eristavad audioraamatu lugeja hääles jutustaja kõnet ning mees- ja naistegelaste otsekõnet. Uurimuse tingis vajadus parandada sünteeshäälega loetavate juturaamatute väljendus rikkust ja kõnestiilide eristatavust. Uurimismaterjalina kasutati professionaalse meeshäälega loetud audioromaani „Tõde ja õigus I“ põhjal loodud korpust. Et teada saada, kas audioraamatu lugeja hääle põhjal on kuulaja võimeline eristama eri kõnestiile (jutustaja kõnet, mees- ja naistegelaste otsekõnet), koostati 48 lausest koosnev tajutest. Testi tulemused näitasid, et kuulajad tundsid ära kõik kolm kõnestiili. Akustiliseks analüüsiks kasutati kogu korpuse materjali. openSMILE’i tööriistaga ekstraheeriti kõnest iga lause jaoks 88 eGeMAPSis defineeritud parameetrit. Statistiliselt oluliselt eristasid kõnestiile 38 parameetrit, millest 18 oli seotud hääle kvaliteedi ja tämbriga, 11 hääle valjusega, 8 hääle kõrgusega ja 1 tempoga. Kuna tajutest ja akustiliste parameetrite analüüs näitasid, et audioraamatus eristusid nii jutustaja kõne, naistegelaste otsekõne kui ka meestegelaste otsekõne, võib pidada otstarbekaks õpetada juturaamatuid ettelugevaid süntesaatoreid esitama kõiki kolme kõnestiili. Märksõnad: audioraamatud, kõnestiil, otsekõne, karakteri kõne, GeMAPS, kõneanalüüs, ekspressiivne kõnesüntees

Objective: We retrospectively analyzed the laryngoscopy results and voice outcomes of patients with vocal polyps who received potassium titanyl phosphate (KTP) laser treatments in a clinician’s office, in order to establish the effectiveness and relative factors affecting the efficacy of this treatment. Material and Methods: We enrolled 25 patients with vocal polyps who had undergone KTP laser treatment in the Department of Otorhinolaryngology at our hospital between July 2017 and November 2019. Pre- and postoperative evaluations were measured using laryngovideostroboscopy (LVS), the Voice Handicap Index questionnaire (VHI-30), the GRBAS scale (G hoarseness, R roughness, B breathiness, A asthenia, S strain), and objective acoustic parameters. The reduction rate of lesions was calculated and relative factors affecting efficacy (size, side, location, the position of lesions, type, gender, and occupation) were tested. Results: Areas of lesions decreased from 101.95 ± 70.16 before surgery to 30.49 ± 35.80 after surgery ( Z = 5.234, P < .001). The LVS data showed that the postoperative proportions of normal to mild conditions were the same or higher than the preoperative data in 3 instances: glottal closure (100% vs 100%), amplitude (90.91% vs 63.64%), and mucosal wave (81.82% vs 54.55%). A significant improvement was observed in VHI-30 scores, GRBAS scores, and acoustic parameters ( P < .05). The size of lesions had an effect on the GRBAS scores ( P < .001) but not on VHI-30 scores and objective acoustic parameters ( P > .05). Other factors we tested did not affect voice outcomes. Conclusion: Potassium titanyl phosphate laser treatment can effectively reduce the lesion area of vocal polyps and improve the voice quality. The presence of small lesions seems to predict good subjective assessments of voice quality, but it remains to be seen whether this correlates with true voice quality.

Background Voice problems caused by pathologies in vocal folds are well known. Some types of laryngeal pathologies have certain acoustic characteristics. Objective evaluation helps characterize the voice and voice problems providing supporting evidences, severity of disorders. It helps assess the response to the treatment and measures the outcomes.Objective The objective of the study is to determine the effectiveness of the voice therapy and quantify the results objectively by voice parameters.Method Study includes 61 patients who presented with different types of laryngeal pathologies. Acoustic analyses and voice assessment was done with Dr. Speech ver 4 (Tiger DRS Inc.). Acoustic parameters including fundamental frequency, jitters, shimmers, Harmonic to noise ratio (HNR), Normalized noise energy (NNE) were analyzed before and after voice therapy.Result Bilateral vocal nodules were the most common pathologies comprising 44.26%. All acoustic parameters showed a significant difference after the therapy (p<0.05) except for NNE. Dysphonia due to vocal fold polyp showed no improvement even after voice therapy (p>0.05).Conclusion Acoustic analysis provides an objective, recordable data regarding the voice parameters and its pathologies. Though, few pathology require alternative therapy rather than voice therapy, overall it has a good effect on glottic closure. As the voice therapy can improve the different indices of voice, it can be viewed as imperative part of treatment and to monitor progression.

Each human being has a voice that is distinct and unique. Extraction and analysis of the features of a person’s voice plays a vital role in diagnosis of diseases in the recent years. The basic parameters used for the voice analysis are Fundamental Frequency (F0), Jitter, Shimmer and Harmonics-to-Noise Ratio. Most of the prevailing Voice Analysis Software are highly commercial with complicated User Interface, requiring expertise to operate them. Hence the proposed study is carried out, which led to the development of a Voice Analysis Application called ‘Ephphatha’. A novel algorithm with improvised measures for voice analysis is used in Ephphatha. The acoustic parameters of duly collected voice samples were analyzed by Ephphatha and compared with the existing algorithms like PRAAT and Multi-Dimensional Voice Program (MDVP) of CSL(Computerized Speech Lab), with F-test analysis. The result showed no significant difference in F0 (p>0.05), except for its Standard Deviation values (p<0.001). The Ratio Of Variance (ROV) is less than or equal to 1 for F0. The other parameters are not significantly correlated. Also it showed that the shimmer values are moderately correlated (p<0.05), when Ephphatha is compared with CSL. It was also seen that all the parameters of PRAAT and Ephphatha have no significance difference (P > 0.05), except for the Shimmer values (p<0.001). Thus Ephphatha would undoubtedly equip the experienced clinicians with its novel approach and better User Interface.

Introduction. Hyperkinetic (hyperfunctional) dysphonia is a common pathology. The disorder is often found in vocal professionals faced with high vocal requirements. Objective. The objective of this study was to evaluate the effects of vocal therapy on voice condition characterized by hyperkinetic dysphonia with prenodular lesions and soft nodules. Methods. The study included 100 adult patients and 27 children aged 4-16 years with prenodular lesions and soft nodules. A subjective acoustic analysis using the GIRBAS scale was performed prior to and after vocal therapy. Twenty adult patients and 10 children underwent objective acoustic analysis including several acoustic parameters. Pathological vocal qualities (hoarse, harsh and breathy voice) were also obtained by computer analysis. Results. The subjective acoustic analysis revealed a significant (p<0.01) reduction in all dysphonia parameters after vocal treatment in adults and children. After treatment, all levels of dysphonia were lowered in 85% (85/100) of adult patients and 29% (29/100) had a normal voice. Before vocal therapy 9 children had severe, 13 had moderate and 8 slight dysphonia. After vocal therapy only 1 child had severe dysphonia, 7 had moderate, 10 had slight levels of dysphonia and 9 were without voice disorder. The objective acoustic analysis in adults revealed a significant improvement (p?0.025) in all dysphonia parameters except SD F0 and jitter %. In children, the acoustic parameters SD F0, jitter % and NNE (normal noise energy) were significantly improved (p=0.003-0.03). Pathological voice qualities were also improved in adults and children (p<0.05). Conclusion. Vocal therapy effectively improves the voice in hyperkinetic dysphonia with prenodular lesions and soft nodules in both adults and children, affecting diverse acoustic parameters.

AbstractIn order to evaluate the vocal quality of tracheo-oesophageal and oesophageal speech, several objective acoustic parameters were measured in the acoustic waveform (fundamental frequency, waveform perturbation) and in the frequency spectrum (harmonic prominence, spectral slope). Twelve patients using tracheo-oesophageal speech (with the Provox® valve) and 12 patients using oesophageal speech for at least two months, participated.The main results were that tracheo-oesophageal voices more often showed a detectable fundamental frequency, and that this fundamental frequency was fairly stable; there was also a tendency to more clearly defined harmonics in tracheo-oesophageal speech. This suggests a more regular vibratory pattern in the pharyngo-oesophageal segment, due to the more efficient respiratory drive in tracheo-oesophageal speech. So, a better quality of the voice can be expected, in addition to the longer phonation time and higher maximal intensity.
