Abstract : This paper presents an exploratory work on the automatic insertion of disfluencies in text-to-speech systems. By inserting pauses, repetitions and revisions, the objective is to make synthetic speech more spontaneous and expressive. To achieve this task, we formalize the problem as a theoretical process, where transformation functions are iteratively composed. This is a novel contribution since most of the previous work either focus on the detection or cleaning of disfluencies in speech transcripts, or solely concentrate on pause insertion in text-to-speech. We present a first implementation of the proposed process using conditional random fields and language models, before conducting objective and perceptual evaluations. These experiments lead to the conclusion that our proposition is effective to generate disfluencies, and highlights perpectives for future improvements.
