Relating formants and articulation in intelligibility test words

The study represents an attempt to describe the relationships between formant histories and lingual fleshpoint movements for selected words spoken by five normal, young-adult speakers of American English. The data are drawn from the X-ray Microbeam (XRMB) Speech Production Database. A major purpose of the study is to examine the appropriateness of simple acoustic-to-articulatory inferences that are common in speech research.
