[Newbies] Controlling cursor by sound

Hello everybody,

some years ago I spend some time with learning squeak. But I forgot most of it and now I wondered whether squeak would be of help with a specific problem.

Would it possible to control elements by sound? Some basic form of voice control. (it would be sufficient to decide between sound and no sound, with some kind of threshold)

E.g. I have an ellipse and I would like to have a construction like

Test Ellipse hears sound Yes Ellipse turn by 90 No Ellipse forward 5

Is there a straight forward solution, or does this requires some deeper digging ?

Thanks a lot Martin
