Eliciting a hierarchical structure of human consonant perception task errors using formal concept analysis

In this paper we have used Formal Concept Analysis to elicit a hierarchical structure of human consonant perception task errors. We have used the Native Listeners experiments provided for the Consonant Challenge session of Interspeech 2008 to analyze perception errors comitted in relation to the place of articulation of the consonants being evaluated for one quiet and six noisy acoustic conditions.
