This report is one of a regular series on the status and progress of speech research. The 16 manuscript topics are: the relative accessibility of semantic and deep structure syntactic concepts, some relationships between articulation and perception, reflex activation of laryngeal muscles by sudden induced subglottal pressure changes, dynamic…
