| Abstract: | In this report, we discuss the initial issues addressed in a research project aiming at the development of an advanced natural speech recognition system for the automatic processing of telephone directory requests. This multi-faceted project involves (1) text processing (labeling and tagging) of a large database of telephone-based natural voice requests (including all kinds of peculiarities,',','), (2) development of robust acoustic models, (3) integrating advanced natural language (syntactic and semantic) constraints, (4) detecting and dealing with a large number of out-of-vocabulary words (proper names,',','), and (5) testing of the resulting system on natural queries. All this work will be performed on the basis of a database containing prompted (read) speech and (simulated) natural requests to information service. This report describes the initial steps that were required to set up a reasonable baseline system and a good research and evaluation framework. More specifically, a significant amount of time was devoted to proper text processing of speaker request transcriptions, in order to create the basis necessary for the lexical and linguistic modeling, as well as for the evaluation of recognition results. |
