Investigation of speech motor skills in cluttering by means of EMMA *Mariam Hartinger & **Christine Mooshammer2 *Queen Margaret University, Edinburgh, **Institut für Phonetik und digitale Sprachverarbeitung Christian-Albrechts Universität Kiel Abstract This study used Electromagnetic Mid-sagittal Articulography (EMMA) to investigate if and how adult people who clutter differ from control speakers in terms of their articulation. The results revealed articulatory differences between these populations in the production of both syllable repetitions and multisyllabic loan words. The syllable repetitions showed fewer specific symptoms of cluttering. In a considerable number of the productions of loan words, clutterers’ however, there was evidence of the reduction and deletion of articulatory movements, in addtion to strongly varying durations and amplitudes of tongue tip movements. 1. Introduction Those characteristics of cluttering that were considered as essential in the present study were: a fast and irregular speech rate, phonological speech errors such as syllable omissions, inappropriate consonant blends or metathesis, and mumbled speech. By using EMMA, the experiment aimed: (1) to examine if a deficit in speech motor skills causes the unintelligible speech in cluttering (Lees, Boyle, & Woolfson, 1996; Daly & Burnett 1996), (2) to investigate the effects of fast speech rate on articulation, and (3) to analyse the spatial and temporal variability
