- Comparison of different speech tasks among adults who stutter and adults who do not stutter(2016) RITTO, Ana Paula; COSTA, Julia Biancalana; JUSTE, Fabiola Starobole; ANDRADE, Claudia Regina Furquim deOBJECTIVES: In this study, we compared the performance of both fluent speakers and people who stutter in three different speaking situations: monologue speech, oral reading and choral reading. This study follows the assumption that the neuromotor control of speech can be influenced by external auditory stimuli in both speakers who stutter and speakers who do not stutter. METHOD: Seventeen adults who stutter and seventeen adults who do not stutter were assessed in three speaking tasks: monologue, oral reading (solo reading aloud) and choral reading (reading in unison with the evaluator). Speech fluency and rate were measured for each task. RESULTS: The participants who stuttered had a lower frequency of stuttering during choral reading than during monologue and oral reading. CONCLUSIONS: According to the dual premotor system model, choral speech enhanced fluency by providing external cues for the timing of each syllable compensating for deficient internal cues.
- Self-perception of people who stutter regarding their experiences and results of stuttering treatments(2014) ANDRADE, Claudia Regina Furquim de; CUNHA, Maria Claudia; JUSTE, Fabiola Staróbole; RITTO, Ana Paula; ALMEIDA, Beatriz Paiva Bueno dePurpose: To investigate the opinion about stuttering treatments in people who stutter, based on their answers to two open questions. Methods: The participants were 40 adults of both genders, with self-reported stuttering. During the first phase of the research, we contacted two Brazilian nongovernmental organizations: the Brazilian Stuttering Association (ABRAGAGUEIRA) and the Brazilian Fluency Institute (IBF). These associations agreed to participate and were responsible for sending the research questions to their members via electronic mail. The first contact with the participants elucidated the purpose and method of our research and, after obtaining informed consent from participants, the two questions were sent. The research questions involved their opinion about cure, treatments to which the participants had been submitted, and their outcome. Results: After analysis, the answers obtained indicated that people who stutter believe in a cure for stuttering; that the ideal therapy would be the one that led to the disappearance of the symptoms; and the most frequently reported professional to treat the disorder is the speech-language pathologist. The results also indicated that although most of the participants had undergone speech-language treatment for stuttering, neither significant improvements were observed nor satisfaction was positive. Conclusion: The results indicate that the answers presented by the participants were not based on scientific knowledge about the disorder but on their wish that ""something could happen"" to make stuttering ""disappear."" Although in this study we did not investigate the type of treatment to which the patients were submitted, the results suggest that the factors that contribute to an effective treatment are contentious.
- Acoustic analyses of diadochokinesis in fluent and stuttering children(2012) JUSTE, Fabiola Starobole; RONDON, Silmara; SASSI, Fernanda Chiarion; RITTO, Ana Paula; COLALTO, Claudia Aparecida; ANDRADE, Claudia Regina Furquim deOBJECTIVES: The purpose of the study was to acoustically compare the performance of children who do and do not stutter on diadochokinesis tasks in terms of syllable duration, syllable periods, and peak intensity. METHODS: In this case-control study, acoustical analyses were performed on 26 children who stutter and 20 aged-matched normally fluent children (both groups stratified into preschoolers and school-aged children) during a diadochokinesis task: the repetition of articulatory segments through a task testing the ability to alternate movements. Speech fluency was assessed using the Fluency Profile and the Stuttering Severity Instrument. RESULTS: The children who stutter and those who do not did not significantly differ in terms of the acoustic patterns they produced in the diadochokinesis tasks. Significant differences were demonstrated between age groups independent of speech fluency. Overall, the preschoolers performed poorer. These results indicate that the observed differences are related to speech-motor age development and not to stuttering itself. CONCLUSIONS: Acoustic studies demonstrate that speech segment durations are most variable, both within and between subjects, during childhood and then gradually decrease to adult levels by the age of eleven to thirteen years. One possible explanation for the results of the present study is that children who stutter presented higher coefficients of variation to exploit the motor equivalence to achieve accurate sound production (i.e., the absence of speech disruptions).
- Comparação da performance de fala em indivíduos gagos e fluentes(2017) COSTA, Julia Biancalana; RITTO, Ana Paula; JUSTE, Fabiola Staróbole; ANDRADE, Claudia Regina Furquim deABSTRACT Purpose The aim of this study was to compare the speech performance of fluent speakers and individuals who stutter during spontaneous speech, automatic speech, and singing. Methods The study sample was composed of 34 adults, 17 individuals who stutter and 17 fluent controls, matched for gender and age. The speech performance of participants was compared by means of three tasks: monologue, automatic speech, and singing. The following aspects were assessed: total number of common disruptions and total number of stuttering-like disruptions. Results Statistically significant difference was observed only for the monologue task in both intra- and inter-group comparisons. Conclusion The outcomes of this study indicate that tasks of higher motor and melodic complexities, such as the monologue task, negatively affect the speech fluency of both fluent speakers and individuals who stutter.

- Diadococinesia sequencial em crianças fluentes e com gagueira desenvolvimental persistente: análise da velocidade e tipo do erro da consoante alvo(2016) JUSTE, Fabíola Staróbole; RITTO, Ana Paula; SILVA, Kalil Garcia do Nascimento; ANDRADE, Claudia Regina Furquim deABSTRACT Purpose To compare the oral motor performance of stuttering and fluent children based on the production rate of sequential diadochokinesis (DDK) and on the type of errors. Methods Participants were 46 children, aged between 4 years and 11 years and 11 months, divided into two groups: Research Group (GI), composed of 23 children with persistent developmental stuttering; Control Group (GII), composed of 23 fluent children, paired by age and gender to participants of GI. For each participant, three samples of sequential DDK were recorded in 15-second windows. These samples were later analyzed considering articulatory rate, and number and type of consonant errors per sample. Results The groups did not present significant differences when considering the analyzed variables. Both fluent and stuttering children presented similar performances for articulatory rate and consonant errors (i.e., the most frequent type of error was consonant exchange). Conclusion Children with developmental stuttering and their fluent peers presented similar performances in all of the tested variables, suggesting that sequential DDK was not enough to identify the stuttering group.
- Impacto do uso do SpeechEasy® nos parâmetros acústicos e motores da fala de indivíduos com gagueira(2015) RITTO, Ana Paula; JUSTE, Fabiola Staróbole; ANDRADE, Claudia Regina Furquim dePurpose To investigate variations in speech motor skills in adults who stutter and those who do not, using the SpeechEasy® altered auditory feedback device. Methods Twenty adults participated, 10 of whom stuttered (nine males and one female - mean age 30.9 years) and 10 of whom were fluent controls (nine males and one female - mean age 25.2 years). The study compared the performance of participants in four tasks: spontaneous speech, alternating diadochokinesis, sequential diadochokinesis and target phrase production, with and without the device. The following variables were analyzed acoustically: (1) diadochokinesis tasks: syllable duration, mean duration between syllables, peak intensity and diadochokinesis rate; (2) target phrase production task: reaction time, voice onset time (VOT) duration, total production duration, fundamental frequency and intensity. Results The spontaneous speech task was the only task to show significant differences in both the intragroup and intergroup comparisons. In this task, the use of SpeechEasy® resulted in significant improvement in speech fluency, as measured by the percentage of stuttered syllables, for the group who stuttered. For the fluent group, the device produced the opposite effect: a significant increase in the frequency of stuttered disfluencies was observed with the device. No significant differences were found in either intragroup or intergroup comparisons relating to the acoustic aspects of the diadochokinesis and target phrase production tasks. Conclusion The results indicated that the use of SpeechEasy® improved the fluency of participants who stutter, without appearing to interfere with speech naturalness.
- Randomized clinical trial: the use of SpeechEasy (R) in stuttering treatment(2016) RITTO, Ana Paula; JUSTE, Fabiola Starobole; STUART, Andrew; KALINOWSKI, Joseph; ANDRADE, Claudia Regina Furquim deBackgroundNumerous studies have demonstrated the benefit of devices delivering altered auditory feedback (AAF) as a therapeutic alternative for those who stutter. AimsThe effectiveness of a device delivering AAF (SpeechEasy (R)) was compared with behavioural techniques in the treatment of stuttering in a randomized clinical trial. Methods & ProceduresTwo groups of adults who stutter participated: group 1 consisted of 10 men and one woman aged 21-42 years (mean = 30.0). Group 2 consisted of six men and one woman aged 20-50 years (mean = 35.6). Participants in group 1 were fit with a SpeechEasy (R) device and were not given any additional training (i.e., supplementary fluency enhancing techniques). Participants used the device daily for 6 months. Participants in group 2 received treatment in the form of a 12-week fluency promotion protocol with techniques based on both fluency shaping and stuttering modification. Outcomes & ResultsThere were no statistically significant differences (p > .05) between groups in participants' stuttered syllables following treatment. That is, both therapeutic protocols achieved approximately 40% reduction in number of stuttered syllables from baseline measures, with no significant relapse after 3 or 6 months post-treatment. Conclusions & ImplicationsThe results suggest that the SpeechEasy (R) device can be a viable option for the treatment of stuttering.
