Effects of practice variability on learning of relaxed phonation in vocally hyperfunctional speakers.

Lee Silverman Voice Treatment (LSVT) has well-documented treatment efficacy for individuals with hypokinetic dysarthria associated with Parkinson's disease (PD). Positive changes have been noted after treatment not only for vocal loudness but also for many other speech dimensions, including intonation (monotonicity). There have been few studies investigating the effect of LSVT on lexical tone which, like intonation, is controlled by variations in fundamental frequency. This study involved 12 Cantonese speakers with idiopathic PD who were enrolled in a standard LVST treatment protocol. Speech data were collected 3-4 days before treatment and 1 day after treatment. A wide variety of perceptual and acoustic variables were analyzed. The results showed significant improvements in loudness and intonation after treatment, but no significant changes in lexical tone. These results have theoretical implications for the relationship between tone and intonation and for models of the physiological control of fundamental frequency.

Effect of LSVT on Lexical Tone in Speakers with Parkinson's Disease

The study examined the effects of focus of attention induced by feedback on motor learning of a relaxed phonation task. Thirteen vocally healthy individuals were randomly assigned into two groups: internal focus group and external focus group. The participants were instructed to read aloud sentence stimuli and were given the surface EMG values measured at their thyrohyoid site as biofeedback. The internal focus group was told that the values represented the muscle tension at the thyrohyoid site. Whereas, the external focus group was informed that the values represented the strained quality of their voice. All the participants were asked to minimize the EMG values for each sentence stimulus. Results revealed motor learning for the trained stimuli at both thyrohyoid and orofacial sites by the reduction in EMG voltages in the delayed retention test. Generalization was also demonstrated to reading against background noise at thyrohyoid site. Nevertheless, the results failed to show differences in motor learning for different foci of attention.
