%X in this paper two acoustic speech analysis systems are presented with applications to the description of spontaneous speech segments and a system of automatic spontaneous speech recognition oriented to word detection. the first analysis system presents in detail all segment and supra-segment instinct speech features simultaneously and associated frequency, power and duration. the second automatically displays the physical parameters associated to intonation in a surface that quantifies the vocal field of the speaker and measures the vocal and dynamic range in spoken discourse. a histogram of the fundamental frequency proves useful to compare intonation tendencies from session to session. finally a recognition tool with acoustic models was developed for spanish spoken in argentina. it transcribes the recorded text sounds and enables the application of other tools for natural language processing.
