Two Brazilian bilingual speech-language pathologists (SLP) translated the original version of the VFI in English into Portuguese. The translations were reviewed by a committee of five voice specialist SLPs resulting in the final version of the instrument. A third bilingual SLP back-translated this final version and the same committee reviewed the differences from its original version. The final Portuguese version of the VFI, as in the original English version, was answered on a categorical scale of 0-4 indicating the frequency they experience the symptoms: 0=never, 1=almost never, 2=sometimes, 3=almost always, and 4=always. For cultural equivalence of the Portuguese version, the option "not applicable" was added to the categorical scale and 20 individuals with vocal complaints and dysphonia completed the index. Questions considered "not applicable" would be disregarded from the Brazilian version of the protocol; no question had to be removed from the instrument. The Brazilian Portuguese version was entitled "Índice de Fadiga Vocal - IFV" and features 19 questions, equivalent to the original instrument. Of the 19 items, 11 were related with tiredness of voice and voice avoidance, five concerned physical discomfort associated with voicing, and three were related to improvement of symptoms with rest or lack thereof. The Brazilian version of the VFI presents cultural and linguistic equivalence to the original instrument. The IFV validation into Brazilian Portuguese is in progress.

Methods The study sample was composed of 50 teachers: 42 women and eight men. The participating teachers were divided into two groups according to the cutoff value of the Voice Symptom Scale (VoiSS): Vocal Risk Group (VRG) and Vocally Healthy Group (VHG). The List of Vocal Signs and Symptoms (LVSS) was used to identify the number of vocal symptoms in each group. The groups were evaluated at three specific moments (before (BT) and after four (4HT) and eight (8HT) hours of teaching) by means of the Vocal Tract Discomfort Scale (VTD scale) and vocal self-assessment. Results The VRG presented more vocal signs and symptoms of the LVSS than the VHG (total: VHG=0.56/VRG=1.60, p<0.001; work-related VHG=0.79/VRG=2.49, p<0.001). The VHG did not report change in discomfort for both frequency (p=1.132) and severity (p=0.431) and showed better vocal self-assessment (BT=0.67; 4HT=0.96; 8HT=0.96, p=0.007). However, the VRG presented vocal tract discomfort after four and eight hours of teaching for both frequency (BT=1.60; 4HT=2.49; 8HT=2.95, p<0.001) and severity (BT=1.79; 4HT=2.52; 8HT=3.12, p<0.001) and worse voice self-assessment (BT=2.00; 4HT=2.42; 8HT=3.00, p<0.001). Conclusion Teachers at vocal risk present worse vocal self-assessment and increased vocal tract discomfort throughout the teaching working day.

Prospective study. Eighteen human voices with different types and degrees of deviation (roughness, breathiness, and strain, with three degrees of deviation: mild, moderate, and severe) were selected by three voice specialists. Synthesized samples with the same deviations of human voices were produced by the VoiceSim system. The manipulated parameters were vocal frequency perturbation (roughness), additive noise (breathiness), increasing tension, subglottal pressure, and decreasing vocal folds separation (strain). Two hundred sixty-nine listeners were divided in three groups: voice specialist speech language pathologists (V-SLPs), general clinician SLPs (G-SLPs), and naive listeners (NLs). The SLP listeners also indicated the type and degree of deviation. The listeners misclassified 39.3% of the voices, both synthesized (42.3%) and human (36.4%) samples (P = 0.001). V-SLPs presented the lowest error percentage considering the voice nature (34.6%); G-SLPs and NLs identified almost half of the synthesized samples as human (46.9%, 45.6%). The male voices were more susceptible for misidentification. The synthesized breathy samples generated a greater perceptual confusion. The samples with severe deviation seemed to be more susceptible for errors. The synthesized female deviations were correctly classified. The male breathiness and strain were identified as roughness. VoiceSim produced stimuli very similar to the voices of patients with dysphonia. V-SLPs had a better ability to classify human and synthesized voices. VoiceSim is better to simulate vocal breathiness and female deviations; the male samples need adjustment.

It was performed a retrospective analysis of PEED-27 questionnaires of 100 individuals with vocal disorder, 37 men and 63 women, mean age of 43.7 in order to compare reduced versions of the instrument. The analysis showed that the three instruments have high level of correlation, thus their results are comparable (PEED 27 x 15, r=+0.910, p< 0.001; PEED 27 x 10, r=+0.873, p<0.001 and PEED 15 x 10, r=+0.924, p< 0.001). The PEED-10 and PEED-15 are reduced and adapted versions to the Brazilian Portuguese language. They evaluate strategies used by dysphonic individuals to cope with their voice problem. The clinician must decide which version to use based on the available time and on the need of more detailed information.

We selected 150 voices from both genders, with quality ranging from neutrality to intense deviations, and predominance of breathiness or roughness. The auditory-perceptual assessment through two scales: 100-mm analogical visual scales and 4-point numerical scale. Intra and interrater reliability of auditory-perceptual ratings was analyzed using the Intraclass Correlation Coefficient. The cut-off values for graduation of roughness and breathiness voices were determinate using the analysis of the Receiver Operating Characteristic (ROC) curve, which is based on the sensitivity, specificity and efficiency. The intra and interrater reliability of auditory-perceptual ratings was excellent on both scales. The cut-off values (mm) in the analogical visual scale, from the numeric scale, indicated a roughness distribution: 0-8.5 absence of the parameter; 8.5- 28.5 mild presence; 28.5- 59.5 moderate and 59.5- 100 intense. For breathiness, the distribution was: 0-8.5 absence of the parameter; 8.5-33.5 for mild presence; 33.5-52.5 moderate and 52.5-100 intense. The cut-off values found for the analogical visual scale conclude that the numerical scale zero, which represents the absence of parameter, corresponds to a small range of scores in the analogical visual scale. Furthermore, the third degree of the numerical scale corresponded to a wide range of the analogical visual scale.

Seventy-three subjects were included in the sample, 33 of which were participants in the experimental group (EG) with diagnosis of PD and 40 were control subjects, that is, healthy and without vocal complaints. They underwent the following procedures: application of Voice Symptoms Scale (VoiSS), Brazilian Version; Voice Disability Coping Questionnaire (VDCQ), Brazilian Version; and the questionnaire Living with Dysarthria (LwD). The EG presented deviations in all protocols: VDCQ, with the most frequently coping strategy being "selfcontrol," VoiSS, with "Impairment" as the most prevalent domain, and LwD, presenting changes in all sections. Vocal signs and symptoms and communicative aspects were shown to have a regular correlation with coping. The correlation between vocal...

This is a prospective study. The auditory-perceptual evaluation was performed by four speech-language pathologists who used two protocols with different scalar properties: the VAS and the 4-point NS. Vocal samples from142 women and 69 men, plus 10% of repetition, with and without vocal complaints, ranging from 19 to 60 years were included. The analyzed speaking task was the counting from 1 to 10. For both protocols, the judges rated the OS. Based on the correspondence between the two scales, the cutoff values of the OS on the VAS obtained were 35.5, 50.5, and 90.5 points. The 35.5 value corresponds to the cutoff point between normal variability and mild/moderate vocal deviations; the 50.5 ...

An analysis of three studies had been made and had compared the data of vocal alteration occurrence, factors that set off vocal problems, vocal symptoms associated to speech and vocal wearing down. On average, 59,1% of the voices had some alteration. Vocal fatigue, teaching time variation and teaching level changed independently of vocal quality. Allergies, how long they have been teaching and their age were related with vocal alteration. Teachers need vocal preparation because professional limitation is frustrating and not good to teaching performance.

To verify the discriminatory ability of human and synthesized voice samples. Study Design. This is a prospective study. Methods. A total of 70 subjects, 20 voice specialist speech-language pathologists (V-SLPs), 20 general SLPs (G-SLPs), and 30 naive listeners (NLs) participated of a listening task that was simply to classify the stimuli as human or synthesized. Samples of 36 voices, 18 human and 18 synthesized vowels, male and female (9 each), with different type and degree of deviation, were presented with 50% of repetition to verify intrarater consistency. Human voices were collected from a vocal clinic database. Voice disorders were simulated by perturbations of vocal frequency, jitter (roughness), additive noise (breathiness) and by increasing tension and decreasing separation of the vocal folds (strain). Results. The average amount of error considering all groups was 37.8%, 31.9% for V-SLP, 39.3% for G-SLP, and 40.8% for NL. V-SLP had smaller mean percentage error for synthesized (24.7%), breathy (36.7%), synthesized breathy (30.8%), and tense (25%) and female (27.5%) voices. G-SLP and NL presented equal mean percentage error for all voices classification. All groups together presented no difference on the mean percentage error between human and synthesized voices (P value ¼ 0.452).

In addition, consistency between the VTD scale and the Voice Handicap Index (VHI) and the Corporal Pain scale was evaluated. A total of 333 participants completed the VTD scale, the VHI, and the Corporal Pain scale. Patient information about study and voice-related hobbies (for students), state of (non)professional voice user (for employees), smoking, shouting, allergy, and voice therapy was taken into account. A median number of three VTD symptoms was reported, and 88% of the participants showed at least one symptom of VTD. Dryness (70%), tickling (62%), and lump in the throat (54%) were the most frequently occurring symptoms. The frequency and severity of VTD were significantly higher in participants who followed voice-related studies, played a team sport, were part of a youth movement, shouted frequently, and received voice therapy in the past (P < 0.05). Finally, low correlations were obtained between frequency and severity of the VTD scale and total VHI score (r = 0.226-0.411) or frequency and intensity of the Corporal Pain scale (r = 0.016-0.408). The prevalence of VTD is relatively high in the Flemish population without self-perceived voice disorders, although the frequency and severity of the symptoms are rather low. Vocal load seems to influence the frequency and severity of VTD. Finally, the VTD scale seems to reveal clinically important information that cannot be gathered from any other protocol.

Métodos: oito repórteres receberam acompanhamento fonoaudiológico virtualmente e oito receberam acompanhamento presencial. Para análise foram utilizadas cópias de duas reportagens, de períodos diferentes (pré e pós-intervenção). As reportagens foram gravadas aos pares, de maneira aleatória quanto à data da exibição/gravação e ao grupo, totalizando dezesseis pares de reportagem. Os materiais, pré e pós-intervenção, foram avaliados por juízes fonoaudiólogos especialistas em voz, cegos quanto ao momento da reportagem. Foram utilizados dois protocolos específicos. Um para avaliação do desempenho na tarefa e de naturalidade dos profissionais e outro para análise auditiva e visual dos parâmetros vocais e interpretativos. Resultados: houve melhora no desempenho comunicativo em ambos os grupos na comparação entre o material pré e pós-intervenção. De acordo com os juízes, 61,53% dos repórteres de ambos os grupos passaram a envolver mais o telespectador à notícia no material pós-intervenção e 69,23% passaram a conversar melhor com o telespectador e a transmitir a notícia de forma mais natural. Quanto ao escore do protocolo de análise auditiva e visual, a maioria dos parâmetros do grupo virtual (postura, gestos, expressões, qualidade vocal, pausas e ênfase) apresentou melhora no momento pós-intervenção na comparação com o grupo presencial que apresentou melhora em apenas um parâmetro (pitch). Conclusão: o estudo mostra que tanto o atendimento presencial quanto o virtual promovem a melhora no desempenho vocal e comunicativo dos profissionais de telejornalismo, confirmando a viabilidade e o resultado da modalidade virtual na prática fonoaudiológica.

Voice disorders were simulated by perturbations of vocal frequency, jitter (roughness), additive noise (breathiness) and by increasing tension and decreasing separation of the vocal folds (strain). Results. The average amount of error considering all groups was 37.8%, 31.9% for V-SLP, 39.3% for G-SLP, and 40.8% for NL. V-SLP had smaller mean percentage error for synthesized (24.7%), breathy (36.7%), synthesized breathy (30.8%), and tense (25%) and female (27.5%) voices. G-SLP and NL presented equal mean percentage error for all voices classification. All groups together presented no difference on the mean percentage error between human and synthesized voices (P value ¼ 0.452).

In addition, consistency between the VTD scale and the Voice Handicap Index (VHI) and the Corporal Pain scale was evaluated. A total of 333 participants completed the VTD scale, the VHI, and the Corporal Pain scale. Patient information about study and voice-related hobbies (for students), state of (non)professional voice user (for employees), smoking, shouting, allergy, and voice therapy was taken into account. A median number of three VTD symptoms was reported, and 88% of the participants showed at least one symptom of VTD. Dryness (70%), tickling (62%), and lump in the throat (54%) were the most frequently occurring symptoms. The frequency and severity of VTD were significantly higher in participants who followed voice-related studies, played a team sport, were part of a youth movement, shouted frequently, and received voice therapy in the past (P < 0.05). Finally, low correlations were obtained between frequency and severity of the VTD scale and total VHI score (r = 0.226-0.411) or frequency and intensity of the Corporal Pain scale (r = 0.016-0.408). The prevalence of VTD is relatively high in the Flemish population without self-perceived voice disorders, although the frequency and severity of the symptoms are rather low. Vocal load seems to influence the frequency and severity of VTD. Finally, the VTD scale seems to reveal clinically important information that cannot be gathered from any other protocol.

Métodos: oito repórteres receberam acompanhamento fonoaudiológico virtualmente e oito receberam acompanhamento presencial. Para análise foram utilizadas cópias de duas reportagens, de períodos diferentes (pré e pós-intervenção). As reportagens foram gravadas aos pares, de maneira aleatória quanto à data da exibição/gravação e ao grupo, totalizando dezesseis pares de reportagem. Os materiais, pré e pós-intervenção, foram avaliados por juízes fonoaudiólogos especialistas em voz, cegos quanto ao momento da reportagem. Foram utilizados dois protocolos específicos. Um para avaliação do desempenho na tarefa e de naturalidade dos profissionais e outro para análise auditiva e visual dos parâmetros vocais e interpretativos. Resultados: houve melhora no desempenho comunicativo em ambos os grupos na comparação entre o material pré e pós-intervenção. De acordo com os juízes, 61,53% dos repórteres de ambos os grupos passaram a envolver mais o telespectador à notícia no material pós-intervenção e 69,23% passaram a conversar melhor com o telespectador e a transmitir a notícia de forma mais natural. Quanto ao escore do protocolo de análise auditiva e visual, a maioria dos parâmetros do grupo virtual (postura, gestos, expressões, qualidade vocal, pausas e ênfase) apresentou melhora no momento pós-intervenção na comparação com o grupo presencial que apresentou melhora em apenas um parâmetro (pitch). Conclusão: o estudo mostra que tanto o atendimento presencial quanto o virtual promovem a melhora no desempenho vocal e comunicativo dos profissionais de telejornalismo, confirmando a viabilidade e o resultado da modalidade virtual na prática fonoaudiológica.
