This paper describes the results of a voice transformation task experiment conducted as part of the evaluation of a speech synthesis system (the GlórCáil system, also described). The participants were required to manipulate the system’s control parameters reflecting changes in voice quality, f0 and vocal tract length of the speaker (VT) in synthetic utterances. A synthetic baseline utterance was manipulated to make it sound like a target speaker (man, woman, child) with affective colouring (sad, angry, no emotion). The control parameters of the system proved useful in modulating speaker characteristics and paralinguistic prosody. The manipulations performed by the participants were mainly in the expected direction. f0 and VT were found to be significant predictors of speaker gender/age, but not of affect. The voice quality related parameter Rd was a significant predictor of affect, but not of speaker identity. Significant interactions of predictors were found for f0 and VT. The control parameter values obtained in this experiment will be used to generate stimuli to test the proposed system when it is integrated into a DNN-based speech synthesis system as part of the ongoing work of the ABAIR project.
