On the depression state and the acoustic parameters of sentence reading

摘要

To grasp the mental state of depression, it is necessary to observe the behavior of patients, by using sume measures such as facial expressions. In this paper, we study the relation between mental state of depression and utterance for sentences with depressive contents. First, we investigate examinee by BDI, then select depressive tasks from BDI, high-depressived Ss (subjects) and low-depressived Ss from the examinee. Second, in the experiment, we made Ss read the task sentences aloud and record the utterances with DAT. Reaction time, amplitude of PCM data and speech rate are extracted and analyzed statistically. Some phonetical features of utterance are found to be influenced by mental state and contents of the sentence.
