We'll be looking at the whole issue of voice recognition at some future point. It has always been problematic with London Control and we will keep everyone advised through the forum once we start to see what we can do to improve it. Voice Access and Speech Recognition (which is being decommissioned in September 2024) both accept voice instructions and respond extremely well, except for London Control. We have always had it in mind to see what we can do to improve it, but it will be a 'future' project.
The only thing I would say is this: in reality, controllers still have to annotate strips (whether paper of EFPS), so the added realism comes from NOT using vox. rec. and driving the strips manually, rather than through voice. And when you're 'pulling your hair out' when it's really busy and you're trying to keep up with traffic, coordination, issuing instructions, annotating strips and all the rest, you get a sense of what the real-world is like. I know, I've been there!
