I’ve used voice activated software occasionally in the past,
but typically given up in frustration. Just got Dragon Naturally Speaking 10.1,
which crosses the line into something truly effective and accurate.
This stuff continues to improve.
This sort of thing can be a help to those musicians who also type a good deal,
because it saves finger/hand use for music and so reduces the chance
of repetitive motion injuries.
There are much reduced prices online, if you look for them.
