ABSTRACT:
An apparatus for the acquisiton of a raw speech signal and the essentially simultaneous acquisition of a transform of the speech signal, wherein said transform covaries as a function of changes in one or more parameters in the speech signal and is indicative of a predetermined selected speech characteristic, such as nasalization, pitch or intensity. The apparatus includes a microphone for producing first signals representative of raw speech, and a second transducer, such as, for example, an accelerometer for generating second signals essentially simultaneous to the production of the first signals, with the second signals being indicative of a selected parameteric characteristic of the human speech, such as, for example, nasalization. The first and second signals are applied to data processing circuits which analyzes the first and second signals to produce transform signals based on arithmetic combinations thereof. The apparatus further includes display means for providing videographic and alphanumeric display of the transform signals accompanied by synchronous audio display of the raw speech.
