Abstract :
[en] Abstract Introduction This study explores how aging may affect speech production. Indeed, there are many changes in motor control processes as well as in the integrity of the laryngeal and supralaryngeal muscles with advancing age that may affect speech production. However, few studies explore these capacities in healthy aging, especially in French. Material and methods We focused on voice onset time (VOT), a speech cue particularly relevant to the study of temporal and spatial coordination between laryngeal and supralaryngeal gestures. Four groups of French-speaking participants of 40-49, 50-59, 60-69 and 70-79 years of age participated. They were presented a non-word repetition task including the six French voiced and voiceless stops /p, t, k, b, d, g/. Results Results show longer non-word durations after 70 years of age, F(3,847)=3.52, p=.02, presumably due to slow down speech movements. In the 70-79 age group, additional issues with initiating and maintaining voicing during stop closure are found, resulting in shorter VOT (delayed prevoicing), F(3,848)=5.23, p=.001, and incomplete voicing (interruption of voicing before stop release) of word-initial voiced /b, d, g/, F(3,422)=3.01, p=.03, which in turn leads to smaller difference in terms of VOT between the voiced and voiceless phonological categories. Discussion These results point to difficulties in articulatory movement coordination potentially signalling an age-related decline in speech motor control.
