Pseudo-Articulatory Representations are increasingly being used in work on speech synthesis and recognition. The value of such representations lies in their derivation from linguistic abstractions -they are based on articulatory idealizations used by linguists to describe speech. Iles [4] has demonstrated that using these representations it is possible to overcome the many-to-one problem in mapping articulatory configuration to acoustic signal. In this paper we show how the representations
