Abstract
Changing the way one hears one's own voice, for instance by adding delay or shifting the pitch in real-time, can alter vocal qualities such as speed, pitch contour, or articulation. We created new types of auditory feedback called Speech Companions that generate live musical accompaniment to the spoken voice. Our system generates harmonized chorus effects layered on top of the speakerﾒs voice that change chord at each pseudo-beat detected in the spoken voice. The harmonization variations follow predetermined chord progressions. For the purpose of this study we generated two versions: one following a major chord progression and the other one following a minor chord progression. We conducted an evaluation of the effects of the feedback on speakers and we present initial findings assessing how different musical modulations might potentially affect the emotions and mental state of the speaker as well as semantic content of speech, and musical vocal parameters.
