The report covers research and development work done from 1 February to 30 April 1975. Areas included in this work are acoustic-phonetics, lexical retrieval, lexical verification, and natural language syntax, semantics, prosodics, and pragmatics. The report consists of two parts -- a brief Survey of Progress containing a few paragraphs describing the major progress in the individual components of the project, and a Technical Notes section containing detailed specifications of experiments performed, programs implemented, design studies, and, where appropriate, supporting data and appendices. This second QTPR contains such technical notes on acoustic-phonetic research, speaker normalization, prosodics, semantic network retrieval, and a new language -- PCOMPILER -- designed for the phonetic and phonological modules of the lexical retrieval component.
