OCS 2007 running a MSS 2004 SALT app: RealSpeak Warning: Unrecognized SSML element extensions RRS feed

  • Question

  • I get the following error  in the event log when I point OCS 2007 to an MSS 2004 SALT app.

    Warning: Unrecognized SSML element extensions
     tag=<salt:prompt id="greeting_wav" xmlns:salt="http://www.saltforum.org/2002/SALT"><audio src="http://blahbah/blah/greeting.wav" originalAttribute="src" originalPath="http://blahbah/blah/greeting.wav" /></salt:prompt>

    I tried the same with another MSS 2004 SALT application and that worked OK. The only difference I see so far is that the working one uses prompt DB where as the one that generates the above error plays the audio file directly.

    Any help is greatly appreciated. Thanks.

  • See this documentation for the salt:prompt element: http://msdn.microsoft.com/en-us/library/ms871806.aspx, specifically option 2:

    • Referenced prompt. Another method to generate prompt speech is to use an external source file. The source file can be either a text-only file or an audio file. If the source file contains only text, the entire file content is spoken to the user. An audio file, however, is played for the user. The path to a referenced path can be relative to the current directory or an absolute path to the file. The prompts can exist on a different server, but as long as a network connection is established, the source file can be accessed. The following example opens a text file named welcome.ssml.

      <salt:prompt id="Prompt1">
        <salt:content type="application/ssml+xml" href="welcome.ssml" />
      The following example uses a .wav audio file. The behavior of the page is identical to that of the preceding example except that the referenced prompt is an audio file.
      <salt:prompt id="Prompt1">
        <salt:content type="audio/wav" href="http://localhost/hello.wav" />
    I.e. change your SALT app to use <salt:content type="audio/wav" href="http://blahbah/blah/greeting.wav"/> instead of the current <audio> element/
