The Speech Fluency Profile of fluent adolescent speakers of Brazilian Portuguese, were examined with respect to gender and neurolinguistic variations. Speech samples of 130 male and female adolescents, aged between 12;0 and 17;11 years were gathered. They were analysed according to type of speech disruption; speech rate; and frequency of speech disruptions. Statistical analysis did not find significant differences between genders for the variables studied. However, regarding the phases of adolescence (early: 12;0-14;11 years; late: 15;0-17;11 years), statistical differences were observed for all of the variables. As for neurolinguistic maturation, a decrease in the number of speech disruptions and an increase in speech rate occurred during the final phase of adolescence, indicating that the maturation of the motor and linguistic processes exerted an influence over the fluency profile of speech.
研究了巴西葡萄牙语流利青少年的言语流畅性特征，涉及性别和神经语言学差异。收集了130名年龄在12岁0个月至17岁11个月之间的青少年（包括男性和女性）的言语样本。根据言语中断类型、语速和言语中断频率对样本进行了分析。统计分析未发现所研究变量在性别之间存在显著差异。然而，关于青春期阶段（早期：12岁0个月至14岁11个月；晚期：15岁0个月至17岁11个月），所有变量均观察到统计差异。至于神经语言学成熟度，在青春期最后阶段，言语中断次数减少，语速增加，这表明运动和语言过程的成熟对言语流畅性特征产生了影响。
