Abstract Speech production is the result of a complex set of interactions between components of the language processing system. The longer the word, the greater the possibility for ‘error,’ because of interactions between word length, stress, CV sequences, consonants and vowels. Nonlinear phonological frameworks influenced by Optimality Theory and connectionist frameworks allow description of output at various levels of the phonological system and their interactions, and thus can help with interpretation of variable speech production patterns. The current paper provides a nonlinear analysis of one 8-year-old’s speech profile, which shows interactions between word structure and segments as word complexity increases. The participant has a rare metabolic condition: 3-methylglutaconic aciduria type I. To date, no reports have described speech profiles of children with this condition and thus, the paper also contributes to the literature on that condition.

La production de la parole est le résultat d’un ensemble complexe d’interactions entre les composantes du système de traitement du langage. Plus le mot est long, plus grande est la possibilité d’une « erreur » à cause des interactions entre la longueur du mot, l’accentuation, les séquences CV, les consonnes et les voyelles. Des cadres non linéaires de la phonologie influencés par la théorie de l’optimalité et des cadres connexionnistes permettent la description de la production à divers niveaux du système phonologique et de leurs interactions, et peuvent ainsi contribuer à l’interprétation des schémas variables de production de la parole. Le présent article offre une analyse non linéaire du profil de parole d’un enfant de huit ans, qui montre les interactions entre la structure d’un mot et ses segments à mesure que la complexité du mot augmente. Le participant a une condition métabolique rare d’acidurie 3-méthylglutaconique de type I. Jusqu’à maintenant, aucun rapport n’avait décrit les profils de parole d’enfants ayant cette condition et, ainsi, l’article contribue à enrichir les connaissances portant sur cette condition.
