Many narrators have limited space in their booth and installing a monitor along with a keyboard and a mouse may not be practical.
A good way to get around this space limitation is to use a tablet and a remote access software like Splashtop or TeamViewer. The audio software is running on the PC outside the booth but the control interface is transferred inside the booth. If you have the space for your paper script, like on the ubiquitous music stand, you most likely have the space for a tablet.
Since Word2WAV is completely paperless, that’s all you need. Use the virtual keyboard if you need to add a comment or create an alternate. Since these actions are the exception rather than the norm during the recording session, it’s not a big hindrance to use this virtual tool.
Note that Word2WAV buttons have been appropriately sized to be used with a touchscreen and using a tablet is a perfect fit.
You may have to test several remote access applications until you find one you like because they each have their pros and cons. I personally like TeamViewer because it makes the tablet a real touch screen interface. You can just touch a button and do not have to drag the cursor on it first.
And a big advantage of a tablet over a standard touchscreen is that it does not generate heat, noise or interference.
If you have the space, you may want to look at Annex III, Efficient Set Up, in the manual.
