From Perceptual Designs to Linguistic Typology and Automatic Language Identification : Overview and Perspectives

In the last years, researches in human identification of languages benefit from a special attention as an alternative to improve the robustness of automatic systems. In this scope, two fundamental goals are pursued: first, to highlight the perceptual strategies used by subjects during an experimental language and/or dialectal identification task and secondly, to identify a set of discriminative cues corresponding to different linguistic levels. Methodologically speaking, two different approaches emerge: one can find experimental designs using natural speech aiming at determining global discriminative cues and/or designs based on modified-speech aiming at isolating specific linguistic levels. These experiments lack of methodology as for the choice of studied languages as well as for subjects’ mother tongue. This aspect being all the more worsened by a hazy spotting and a limited exploitation of discriminative criteria. We suggest an original approach based on a two-step methodology integrating to perception "genetic" considerations and resulting into the modeling of perceptually identified discriminative cues.
