How to: Validate a .grxml Grammar File
This content is no longer actively maintained. It is provided as is, for anyone who may still be using these technologies, with no warranties or claims of accuracy with regard to the most recent product version or service release.
Use the Speech Grammar Editor validation tools to ensure that Speech Server .grxml grammar files are valid.
The Recognition string check feature of Speech Grammar Editor can fail with a cryptic error unless you either:
- Remove the lexicon element from the .grxml file, which is added by default when a new .grxml file is created.
- Open the project's .cal file and click Build to build the .lex file. The lexicon element in the .grxml file references a .lex file that does not exist until the .cal file is built.
The cryptic error message previously mentioned is as follows:
SML output failure: Speech Recognizer is having problems with this grammar. Make sure that all external Grammars exist and are valid, and any external Rules being referenced have their Scope property set to "Public".
