... Concurrently, spontaneous speech is increasingly used in TTS [7,8]. Spontaneous speech data is challenging to model, due to disfluencies and large variability [9]; offers high ecological validity for evermore commonplace conversational AI systems; and the varied prosody offered by spontaneous data positively impacts factors such as word recall and attention [10]. For conversational systems it would also be useful to be able to synthesize creaky phonation, as this have been found to be a strong turn-yielding cue [11,12]. ...
