If a person has a speech impairment or has trouble speaking, he/she may not know what to change to improve his/her speech quality. This is a serious problem often seen by speech therapists where they try to explain to their patients that they are mispronouncing a particular sound. The patient must then attempt to keep changing the sound until they have recreated the correct sound. This is quite difficult and sometimes does not work. The same scenario occurs with speech devices that provide feedback to the person speaking. For example, the IBM product- SPEECH VIEWER, gives the person a problem/goal in the form of a game, and if the person says the word or sound correctly, the game pieces move in the correct direction. This also does not give the person any information as to how to place their tongue, open their mouth, or place accents it simply provides feedback that the speaker has hit the desired target. It does not offer incremental feedback about how the speaker can gradually approximate this target. Summary of the Invention The invention gives a person feedback as to how to manipulate and place the articulators responsible for speech (mouth, lips, tongue, jaw, etc....) while they are speaking, in order to improve the quality and intelligibility of their speech. There are methods that allow for the measuring and taking an image of tongue, throat, or even lip placement at any given moment. But to more effectively improve speech production, it is necessary to have more dynamic methods that give feedback on both articulatory placement as well as acoustic output.
