Through the present paper, a methodology to create Visual Representations of Speech for Speech Perception Enhancement Applications, based on the use of a Continuous Formant- Tracking Algorithm, is presented. The specific mathematical and computational issues introduced for such treatment are given, and a specific case for Computer-Aided Language Learning oriented to the Phonetic Specificities of English for Spanish Speakers is also presented. This specific technique may also be used in statistically normalizing Speech Data for Speech Recognition Systems. In this context, an example of a Robust to Noise Speech Recognizer, which uses Eormant Dynamic Information is shown.
