Abstract

Apparatus for interactive speech training having an audio specimen generator for playing a pre-recorded reference audio specimen to a user for attempted repetition by the user and a reference audio specimen library in which reference audio specimens are stored and to which the audio specimen generator has access. The audio specimen library contains a multiplicity of recordings of speaker dependent audio specimens produced by a plurality of speech models. A speaker independent parameter database stores a plurality of speaker independent references which are different from the reference audio specimens stored in the reference audio specimen library. The speaker independent references are classified according to at least one of age, gender or dialect, but is independent of other speaker characteristics within each category. An audio specimen scorer scores a user's repetition audio specimen by comparison of at least one parameter of the user's repetition audio specimen with a speaker independent reference.
