With regard to your feedback on our guide doc [1]

VoiceXML applications don't describe errors in "text" but in speech
(preferably synthesized speech so that there is text available somewhere if
there should be a system for deaf users to access VoiceXML applications).
Maybe the SC should read: "If an input error is detected, the error is
identified and described to the user in the same modality that is used for
labels, prompts and other guidance in the form/interaction."
Writing VoiceXML techniques for this SC should be easy (VoiceXML has
noinput , nomatch and reprompt elements) but is low priority; they could go
to the "boneyard" for GL 2.5.

If the VoiceXML application is using synthesized speech, then the errors
are described in text aren't they? They just happen to be rendered by a
speech synthesis engine. And if the application is using recorded speech
for errors, then it would have to provide a text alternative in order to
meet GL 1.1. In either case, if the application is being rendered by an AT
for deaf users, the text is there isn't it? So is this really a problem?

If you still think it's a problem, we thought your suggested wording was a
little verbose and came up with an alternative suggestion. We could propose
changing the SC to "If an input error is detected, the error is identified
and described to the user." Would this resolve the issue?
