If you are looking for somewhere on how to explain how to test the Nuance product Dragon Naturally Speaking then you are in the right place.
There is a mac version of Dragon, but it isn't anywhere near as good as the Windows version. First we need to set up a VM with windows and then install a trial version of dragon to test it out.
Creating a virtual Windows environment
At the minute I can only find version 13 for free on this site
Put everything together
You need to put the downloaded file somewhere the VM can reach it. You can see where this is setup on your machine from the properties window in virtualbox
If you want to test something running locally on your mac then in the VM add
10.0.2.2 localhost to your host file
You should be able to access
localhost:<port> now through the VM
Start up the windows VM. Run the downloaded dragon .exe file and follow the instructions. It might take a while to download.
You should end up with a running version of Windows and Dragon for 30 days.
