Several full-featured visual VoiceXML development environments have appeared recently. These work in much the same way that Visual Java works, with the exception of lacking a compiler. These visual development environments include a visual editor, a debugger, grammar builders, grammar modules, and many other features. Some of these packages include modules for dynamically generating VoiceXML. 4. Tune end points.
End points are parameters that describe the speech recognition listening window.
Examples of these parameters include the expected length range of an utterance, expected amount of silence on either end of the utterance, and other parameters that describe how the utterance is processed. Tuning the end point parameters can have a dramatic effect on the ability of the speech recognizer to determine what voice command was spoken. Developers may want to enlist tools and professional services from their ASR provider to complete this step of the project, at least the first time. All rights reserved.
