基于TTS技术和脑电采集设备的精神疲劳实验系统设计与实现

摘要

In the mental fatigue study, an experiment system which can objectively reflect the mental fatigue state is the basis of study. Based on the technology of Text To Speech and combined with EEG acquisition equipment, a mental fatigue experiment system was developed in the VC++ environment with Microsoft Speech SDK, TTS engine and Microsoft MFC Foundation Class library.The experimental results showed that applying the TTS technology to the mental fatigue experiment system helped to improve the flexibility of the experiment greatly and achieve the accurate calibration of fatigue state.%在精神疲劳研究中,能客观地反映精神疲劳状态的实验系统是研究的基础.本文基于语音合成技术TTS,结合脑电采集设备,利用Microsoft Speech SDK语音开发包、TTS引擎和微软MFC基础类库,在VC++环境下设计并实现了精神疲劳实验系统.实验结果表明,将TTS技术应用于精神疲劳实验系统,大大提高了实验的灵活性,能实现疲劳状态的准确标定.
