The VoiceXML Forum is open to any company interested in
Internet information and content becoming voice and phone accessible.
Companies may join as Supporters, Contributors, or Adopters after the
initial draft specification is released publicly for comment. The
initial VoiceXML language specification will be based upon
characteristics and functionality that includes Phone Markup Language
or PML, an extension of the HTML language from AT&T, IBM, Lucent and
Motorola 's VoxML.
