Communicating emotion is essential in building and maintaining relationships. We communicate our emotional state not just with the words we use, but also how we say them. Changes in the rate of speech, short-term energy and intonation all help to convey emotional states like 'angry', 'sad' and 'happy'. People with dysarthria, the most common speech disorder, have reduced articulatory and phonatory control. This can affect the intelligibility of their speech, especially when communicating with unfamiliar conversation partners. However, we know little about how people with dysarthria convey their emotional state, and whether they are having to make changes to their speech to achieve this. In this study, we investigated the ability of people with dysarthria, caused by cerebral palsy and Parkinson's disease, to communicate emotions in their speech, and we compared their speech to that of speakers with typical speech. A parallel database of emotional speech was collected. One female speaker with dysarthria due to cerebral palsy, 3 speakers with dysarthria due to Parkinson's disease (2 female and 1 male), and 21 typical speakers (9 female and 12 male) produced sentences with 'angry', 'happy', 'sad', and 'neutral' emotions. A number of acoustic features were analysed using linear multi-level modeling. The results show that people with dysarthria were able to control some aspects of the suprasegmental and prosodic features when attempting to communicate emotions. For most speakers the changes they made are consistent with the changes made by speakers with typical speech. Even when the changes might be different to that of typical speakers, acoustic analysis shows these were consistent for different emotions. The analysis shows that variation in energy and jitter (local absolute) are major indicators of emotion in the study.

交流情感对于建立和维持关系至关重要。我们不仅通过使用的单词交流情绪状态，而且还通过语言表达他们的情感状态。言语速度，短期能量和语调的变化都有助于传达“愤怒”，“悲伤”和“快乐”等情绪状态。构音障碍是最常见的言语障碍，人们的发音和发声控制降低。这可能会影响其语音的清晰度，尤其是在与陌生的对话伙伴进行交流时。但是，我们对于构音障碍患者如何传达情绪状态以及是否必须改变其言语才能实现这一点知之甚少。在这项研究中，我们调查了由脑瘫和帕金森氏病引起的构音障碍患者的能力，交流他们讲话中的情感，我们将他们的讲话与典型讲话者的讲话进行了比较。收集了一个并行的情感演讲数据库。一名因脑瘫而引起构音障碍的女性说话者，3名因帕金森氏病而引起的构音障碍的女性说话者（2名女性和1名男性）和21名典型的扬声器（9名女性和12名男性）的句子带有“愤怒”，“快乐”，“悲伤”和中立的情绪。使用线性多级建模分析了许多声学特征。结果表明，构音障碍患者在尝试传达情感时能够控制节段上和韵律特征的某些方面。对于大多数发言者而言，他们所做的更改与具有典型语音的发言者所做的更改是一致的。即使变化可能与典型说话者的变化不同，声学分析也表明这些变化对于不同的情感是一致的。分析表明，能量和抖动（局部绝对值）的变化是研究中情绪的主要指标。
