Ultraspeech-player - Intuitive visualization of ultrasound speech data

Ultraspeech-player is a standalone software dedicated to the visualization of ultrasound speech data recorded using Ultraspeech.

Ultraspeech-player is designed for speech therapy protocols which use visual information to increase the articulatory awareness of a speaker.The originality of this tool resides in the fact that it combines a video retiming technique with an audio time-stretching algorithm. Ultraspeech-player allows the user to slow-down in real-time both the articulatory gesture and its corresponding acoustic realization (i.e. the speed of the audio signal is modified while the original pitch it preserved). This rendering technique aims at improving the way a naïve speaker perceive and understand a tongue gesture.
