Automatic speech-based assessment of mental state via mobile device

该项目旨在创建第一个基于移动设备的语音心理状态自动评估。该项目将语音处理从实验室带到了现实环境中，重点关注引出语音、基于回归的精神状态评分和语音纵向建模的新方法。该项目意义重大，因为启发方法和纵向建模已被研究界公认为有价值的研究挑战，并且因为传统的回归方法在有序精神状态量表上是次优的。这在商业上意义重大，因为移动设备允许进行个性化、频繁和低成本的精神状态评估。预期的结果将包括商用技术，在澳大利亚进行试验，每个人都可以使用移动设备，并将澳大利亚的研究和开发能力集中在一个快速增长的应用领域。

This project aims to create the first mobile, device-based automatic assessment of mental state from acoustic speech. Focusing on novel approaches for eliciting speech, for regression-based scoring of mental state and for longitudinal modelling of speech, the project takes speech processing out of the laboratory and into realistic environments. The project is significant because elicitation approach and longitudinal modelling have been acknowledged by the research community as challenges that are valuable to investigate, and because conventional regression methods are sub-optimal on ordinal mental state scales. This is significant commercially because mobile devices allow individually tailored, frequent and low-cost mental state assessment. Expected outcomes will include commercial-ready technology, trialled on Australians, accessible to everyone with a mobile device and concentration of Australian research and development capability in a rapidly growing application area.
