I bought and installed the HCS Aviator voicepack yesterday and it seems to do what it says on the tin.
I didn’t get too much time to try it out though, as i had to reinstall VoiceAttack, Vaicom Pro and my other HCS voicepacks, due to a recent reinstall of Windows.
I had also forgotten to export my Windows Speech Recognition profile before that reinstall, so ended up having to go through a few speech recognition training sessions and will need to re-add the DCS Russian airport names to the dictionary again. I’ll learn.
