We have tested a fixed version of the Fluency foreign
language pronunciation trainer to determine whether users
actually improve their pronunciation through its use. The
Fluency system uses the CMU SPHINX II speech
recognizer to pinpoint pronunciation errors and then gives
suggestions as to how to correct them. Users in the
experiment we will describe in this paper were to learn to
pronounce the voiced and voiceless interdental fricatives
/Θ/ and /δ/, as in "thin" and "that."
The choice of these
two phones allowed us to attract users from several native
languages. In this paper, we present the results of this
study, fully describing the test situation and drawing
conclusions about Fluency as a testbed.
