This paper introduces Ultraspeech-player, a software dedicated to the visualization of ultrasound and video sequences of the tongue and lips. This software is designed for speech therapy and pronunciation training applications and aims at increasing the articulatory awareness of the learner. Ultraspeech-player includes an audiovisual time-stretching algorithm allowing the user to slow-down in real-time both the articulatory gesture and its corresponding acoustic realization. This rendering technique aims at improving the way a naive speaker perceives and understands an articulatory gesture.
