Practise copying random QSO using this highly-customisable tool:
The Play button plays the current message and you can move on to a new message when you are ready with the Next button. Play Next moves on and plays with one click.
If you have Repeat pressed and then press Play, the current message will be repeated for ever. Repeat with Play Next provides continuous random play.
Each message can be played one to five times or repeat forever by using the Count button. If Count is set to repeat forever, you can press the Next button to move on.
If you use the speech function then the pause between words might be longer than you specify: it makes sure that the speech finishes before moving on.
The semi-random sentences created do have a few limitations at the moment. There is not much variety in names and places or control over the QSO content. However, I hope it will already be useful and these things will be improved soon.
