Join Chris Nodder for an in-depth discussion in this video Voice control, part of Interaction Design for the Web.
- There's a scene in the movie Blade Runner…where the lead character uses voice commands…to analyze a photograph.…He must tell the device which sector to enlarge or enhance…and where to zoom, pan, or rotate.…The scene lasts for several minutes.…The same activity would have taken less than 10 seconds…with a touch interface.…Voice control is great in some situations…and not so great in others.…If you have your hands full, if you're wearing heavy gloves,…or if you can't easily reach…the device you're trying to control,…then being able to give verbal instructions…is a real advantage.…
However, if you're in a loud environment…or even if there are several people talking…at a regular volume, voice interfaces can get confused.…If you have an ambiguous command,…then you might end up playing a game of 20 questions…while the device tries to narrow down who…or what exactly you meant to apply the command to,…when, and how.…And like I described just now,…using voice commands for manipulation tasks…can be incredibly cumbersome.…
