Detailed Description

A subclass of LocalTalkative that sends "SayText" commands to a festival server.

Use FestTalk::registerExtenders() to register FestTalk as a local metaobject, and regular RemoteTalkative as a remote metaobject, with the factory.

Author:

reed 12/01

Bug:

Due to a possible bug in Festival the first "say" message fails. Manually send an initial message (with do_say) to get around this.
