Hi Mark. Home Page Reader does the same and plans the same. So far there are no candidates for the "Many assistive technologies that ... " I feel strongly that making statements like that triviallizes a the efforts of folks doing assistive technologies.

The LANG attribute is specified in the HTML element. 2. The LANG attribute corresponds to one of the installed synthesizer languages. Users can manually switch the "reading" synthesizer to one of the installed languages, if no LANG attribute is present. Presently we don't switch on LANG attributes within a page (though we are likely to add that). We do note significant time delays when switching between some synthesizers (eg, some SAPI engines may exhibit a long load time, particularly when using engines from different vendors). That has been a concern of mine if we switch on arbitrary LANG attributes appearing in the page as it could introduce unnatural reading flow. mark > -----Original Message----- > From: w3c-wai-ua-request@w3.org [mailto:w3c-wai-ua-request@w3.org]On > Behalf Of thatch@us.ibm.com > Sent: Wednesday, November 24, 1999 6:24 PM > To: Al Gilman > Cc: w3c-wai-ua@w3.org > Subject: Re: Techniques for 2.2.3 > > > > > For goodness sake.
