SpeechWorks has implemented the W3C Speech Recognition Grammar 
Specification fully in OpenSpeech Recognizer, our high performance 
network-based speech recognition engine that is optimized for VoiceXML 
applications. Through this native implementation we provide an easy path 
for telephony platform vendors to support the grammar specification in 
their own DTMF- and ASR-capable products. The SpeechWorks implementation 
features complete multilingual capabilities allowing arbitrary grammatical 
constructs using an unlimited number of languages and Unicode character 
encodings, along with embedded ECMA-262 scripts for application-specific 
search pruning and semantic result computation. Based on our own experience 
and feedback from many partners and customers, we give a strong endorsement 
to SRGS as practical, expressive, and complete.

The complete test results are attached.

Note: While we did implement language attachments on rule references, this 
feature was found to be unnecessary and confusing to many users.  We 
support its removal.
