ABSTRACT:
An apparatus for drilling the pronunciation of language has a transducer for forming drill voice signals representing a practice utterance of a trainee and a reproducer for generating reference voice signals representing model pronunciation of the utterance. The drill and reference voice signals are compared by a processor and a sensible signal is produced to indicate whether the practice utterance corresponds to the model pronunciation.
