SALT Forum Companies Back VoiceXML


Note [April 2007]: I stopped updating this page in 2005 as VoiceXML made huge gains and news of SALT began to dry up.  Microsoft has since added VoiceXML 2.0/2.1 support to Microsoft Speech Server, joined the VoiceXML Forum, and has successfully completed the Forum's VoiceXML 2.0 platform certification process. And now with its acquisition of TellMe Networks about to be completed, Microsoft stands poised to become the largest VoiceXML company in the world!


We used to hear a great deal from the press about a standards battle between SALT and VoiceXML.  It made for good copy, but the marketplace reality is that W3C's VoiceXML 2.0 standard predominates.  This is most evident when you look at how SALT Forum member companies are behaving -- most are making huge commercial bets on VoiceXML 2.0.  The average SALT Forum company is more fervently behind VoiceXML 2.0 than the average VoiceXML Forum member company!

Here is a sampling of recent pro-VoiceXML press releases and public statements from SALT Forum companies (  An "n/a" entry means I haven't yet found any publically-available information on the company's usage of VoiceXML or SALT.  If you have any corrections or additions, please drop me a line at ferrans at  While I don't explicitly track SALT-only news here, SALT Forum companies make three times as many announcements relating to VoiceXML as they do regarding SALT.
