New Device to help with stuttering

This reminds me of watching a video where a speech therapist tells a teen to feel his throat while he is speaking.  I hope this device is available and affordable to all who need it.  This should be able to work whether in a crowded restaurant, on a noisy street, or while giving a presentation.  The auditory feedback devices are only useful for individual speaking situations with no other noises in the background.
