How Far Are We in Understanding Neuroscience and Voice, A Review

Mette Pedersen

The fluency and the reliability of voice production depends on a mechanism that links motor commands and sensory feedback, as the main signal processing. Studies of the neural organization of fMRI identifies regions where activity during speech production is modulated and where predicted outcome is regulated. We have earlier studied phonetograms of young brain damaged people, showing no intensity modulation of frequency in a two octave test. We have also shown a relationship between measurements of high speed films and pharmacological treatment in dystonia patients, showing that these methods might assist in diagnosing brain defects related to voice. The focus here is to get on to understand how neuroscience aspects can help us in voice treatment documentation.
