GURLEKIAN, Jorge A; EVIN, Diego; TORRES, Humberto  y  RENATO, Alejandro. Acoustic Analysis and Automatic Recognition Systems in spontaneous speech. Subj. procesos cogn. [online]. 2010, vol.14, n.2, pp.89-98. ISSN 1852-7310.

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.

Palabras clave : Acoustic analysis; Automatic speech recognition; Fundamental frequency.
