    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 de
    ABSTRACT 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 de
    Purpose 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.
