Improving fundamental frequency modulation in head trauma patients: a preliminary comparison of speech-language therapy conducted with and without IBM's Speech Viewer.

This study involves a preliminary comparison of traditional speech therapy for head trauma patients with therapy assisted by computer. Two subjects were treated in a 'crossover' design to compare the effects of each treatment. While both subjects improved, there was no obvious difference in treatment effectiveness. However, the computer support provided the measures of treatment efficacy which made this comparison possible.
