Attention-Deficit Hyperactivity Disorder (ADHD) is a predominant neurobehavioral disorder of childhood with motor and sensory symptoms often persisting into adulthood. Motor control theories highlight the importance of the bidirectional relationship between sensation and movement for maintaining skilled behaviors like speech. The impact of ADHD on speech in adults has not been well established. The purpose of this study is to assess group differences in quantitative speech and oral somatosensory measures in adults with and without ADHD and to describe the relationship between ADHD symptomology and speech production. A total of 50 adults (18–26 years) were recruited and divided in two groups based on diagnosis: those with (n = 28) and those without (n = 22) ADHD. All participants provided a speech sample to measure articulatory accuracy and speech rate and completed quantitative point-pressure testing using tactile detection and discrimination on bilateral sites on the lower lip and lateral edge of the tongue tip. Independent t-tests corrected for multiple comparisons identified significant group differences using FDR corrected q values in speech production for correct syllables per second and overall speech rate (q<.05). Additionally, there were significant group differences (q<.05) for detection and discrimination threshold estimates at one testing location. Bivariate correlations identified a relationship between several speech measures and self-reported ADHD symptoms such that as symptom severity increased, speech accuracy for correct syllables per second decreased. Young adults with ADHD have subtle differences in speech production compared to non-ADHD control participants. Speech scientists might consider screening for ADHD when collecting normative data samples.

注意力缺陷多动障碍 (ADHD) 是一种主要的儿童期神经行为障碍，其运动和感觉症状通常持续到成年。运动控制理论强调了感觉和运动之间的双向关系对于维持言语等熟练行为的重要性。 ADHD 对成人言语的影响尚未明确。本研究的目的是评估患有和不患有 ADHD 的成年人在定量言语和口腔体感测量方面的群体差异，并描述 ADHD 症状与言语产生之间的关系。总共招募了 50 名成年人（18-26 岁），并根据诊断分为两组：患有 ADHD 的人（n = 28）和没有 ADHD 的人（n = 22）。所有参与者都提供了语音样本来测量发音准确性和语速，并使用触觉检测和辨别下唇和舌尖侧缘的双边部位完成了定量点压力测试。针对多重比较进行校正的独立 t 检验使用 FDR 校正语音生成中的 q 值来确定每秒正确音节和总体语速 (q<.05) 的显着组差异。此外，在一个测试地点的检测和辨别阈值估计存在显着的组间差异 (q<.05)。双变量相关性确定了几种言语测量与自我报告的多动症症状之间的关系，例如随着症状严重程度的增加，每秒正确音节的言语准确性下降。与非多动症对照参与者相比，患有多动症的年轻人在言语产生方面存在细微差异。言语科学家在收集规范数据样本时可能会考虑筛查多动症。
