Performance assessment of speech recognisers is certainly one of the major area of interest in the field of Speech Processing Technology; the reasons for such an interest stem from the in- trinsic difficulty of the task in terms of repeatability, reliability and validity of the results. It is in fact meaningless to declare any performance measurement without specifying the boundary conditions in which those results were achieved. This consideration becomes even more crucial when the telephone environment is concerned.
The paper covers two separate aspects : the generation of telephone grade speech corpora and the assessment of a speech recogniser with both clean and telephone grade speech corpus, the latter being derived from the clean speech version. For the first aspect, the paper describes a complete procedure to generate telephone grade speech corpora; it could be used either to generate completely new corpora or to degrade a given clean corpus to its telephone grade equivalent. Concerning the second aspect, the paper focusses on a European standard multi-lingual corpus, the EUR0MJ3 CD ROM that has been used twice for a comparative assessment of the same speech recogniser.
