title: [Voice onset time in Friedreich dysarthria].
abstract: This study concerned VOT measurements of voiced and voiceless occlusives produced in a sample of spontaneous language from 16 French speakers with Friedreich's ataxia. The results revealed that average VOT values were positive for voiceless stops and negative for voiced stops and thus were in agreement with published data for French. There was, however, a reduction of the difference between the two voicing categories and large between-subject variability. The factors that could have contributed to the increase in between-subject variability and to the reduction of the difference between the two categories are discussed. Finally, some leads for the use of VOT in the therapeutic process are proposed.
