- Test keyboard navigationWhen doing things by voice doesn’t work directly the user can revert to using keyboard commands by voice.Label everything, inc. form elementsFor something to be clickable it must be associated with some text that is pronounceable.Use unambiguous labels that are pronounceable. Do not use lots of identical labels (e.g. click here). Make it clear what the labels are for form elements.Avoid frames or use sparinglyMoving from one frame to another is quite difficult by voice, especially if there are scrollbars within any of the frames.Use standard Windows/HTML controls (buttons and text entry boxes especially)Java applets are notoriously badVisual design often trumps functionality, especially where accessibility is concerned.Ensure cross browser compatibilitySpeech recognition users are often restricted to particular browsers.
