Abstract: The provision of speech therapy to a learner (76) entails receiving a speech signal (156) from the learner (76) at a computing system (24). The speech signal (156) corresponds to an utterance (116) made by the learner (76). A set of parameters (166) is ascertained from the speech signal (156). The parameters (166) represent a contact pattern (52) between a tongue and palate of the learner (156) during the utterance (116). For each parameter in the set of parameters (166), a deviation measure (188) is calculated relative to a corresponding parameter from a set of normative parameters (138) characterizing an ideal pronunciation of the utterance (116). An accuracy score (56) for the utterance (116), relative to its ideal pronunciation, is generated from the deviation measure (188). The accuracy score (56) is provided to the learner (76) to visualize accuracy of the utterance (116) relative to its ideal pronunciation.

Abstract: 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.

Abstract: A method for utilizing oral movements is used in speech assessment, speech therapy, language development, and controlling external devices. A device is used which includes a sensor plate having sensors to detect contact of the tongue with the sensor plate. One aspect of the invention allows viewing representations of contact of the tongue and palate during speech and comparing the representations with model representations displayed in a split screen fashion. The model representations may be generated by another speaker utilizing a sensor plate or by computer generated representations which have been electronically stored. The representations may be analyzed to assess speech proficiency and the model may be mimicked for speech enhancement.

Abstract: A pseudo palate is formed of a thin sheet of material shaped to the contour of the palate of a person whose speech is to be tested. On the lingual surface of the sheet is an array of electrodes located in the lingual contact areas of the palate and spaced apart predetermined distances. Conductors attached to the electrodes are embedded in the sheet and are grouped together in at least one bundle to exit from the palate at its posterior, into the buccal cavity of the patient's mouth where the bundle of conductors may exit from the mouth at a corner thereof. These conductors are attached to suitable instrumentation which may give a visual or possibly aural signal corresponding to the position of the tongue when the patient makes, or attempts to make, designated speech sounds.
