A palatometer and nasometer apparatus is disclosed for the diagnosis and treatment
of speech impairment, new language sound learning, and other uses. The palatometer
includes a palatal body containing electrodes which fits in a user's mouth. Contact
between the user's tongue or lips and the electrodes is indicated on display equipment.
The palatometer and display equipment operate to indicate the position and movement
of the tongue and lips. The nasometer includes interchangeable sound separator
plates to fit users with different facial curvatures. Microphones are attached
to the top and bottom of the sound separator plate to measure sound emitted from
the nose and mouth for determining the nasality of speech. The palatometer and
nasometer are combined to optimize the ability to define speech normality as well
as diagnose and remediate speech.
