Thanks very much for your post. We spotted that story on BBC news too and tweeted it earlier today.
I'll also pass on your thoughts about potentially incorporating taking 'voice samples' as part of the Tracking Parkinson's project.
It may be something we could do in a some cases and we are looking into different ways to expand the study to make it as useful as possible.
In fact, just last week we launched a new grant round on proteomics which links into Tracking Parkinson's:http://www.parkinsons.org.uk/proteomics_researchgrant
