Methods, devices, and computer program products display visual choral speech
to a patient who stutters or has a speech impediment or impairment as a visual
stimulus for the patient to enhance the fluency of the patient. The visual choral
speech is incongruous with the speech produced by the stutterer and is provided
by a visual display of the articulatory movements of a person other than the patient
(or a simulated representation thereof) of the person's lips and mouth as the person
speaks. The visual speech gestures can be displayed to the patient in advance of
a speaking event or speech production by the stutterer and/or concurrently with
a speaking event (either intermittently or continuous during the speaking event).
The visual choral speech gestures can be based on a string of coherent words to
provide the visual speech gestures signal such that it is relayed to the user without
the attendant auditory component allowing the user to speak at a substantially
normal pace with enhanced fluency.
