Saurabh,

Both the ABNF Form and XML Form of the Speech Recognition Grammar Spec
restrict the content of a single grammar document to a single mode.
"voice" and "dtmf" modes are defined in the 1.0 specification.

So with the current spec is it not legal for a single grammar to 
contain both DTMF and speech tokens.

Note that it is legal to activate a DTMF grammar and a speech grammar 
in parallel on a VoiceXML browser / grammar processor that supports this.
