Thank you for your recommendations. I am using windows seven, and if I'm honest the voice recognition is shockingly poor. I have been working at training it to recognise my voice for three days now and still it has only around 30 percent accuracy. Is it normal for it to be so bad after so many hours of training? If so I shall persevere.
For what it's worth people frequently compliment me on my clear enunciation so I do not believe the fault to be there.
