Similarity of Effects of Emotions on the Speech Organ Configuration with and without Speaking

In this work we propose and verify a hypothesis on emotional speech production: emotions induce physical and physiological changes in the whole body including the speech organs, regardless of whether or not the person is speaking, and as a side effect, this changes the voice quality. To verify this hypothesis, we measured the speech organ configuration of actors simulating four emotions (neutral, hot anger, joy, and sadness) with and without speaking by MRI. The results showed that emotions affect the speech organ configuration, and the same tendency of changes was found regardless of whether or not the person was speaking.
