	About Phrasesets

Phrasesets are used to group phrases, usually all related to a particular speech application. Phrases are used to build prompts, which in turn are used to guide the caller through the call flow.

The main advantage for grouping phrases, aside from better organization is that with phrasesets, file resource efficiencies are greatly improved which translates into quicker build times. With a phrase, there are four files per phrase (one .phrase file, one .java file, one java .class file, and one .wav file for every phrase), so when there are 1000 phrases in a project, there are actually 4000 files that need to be managed and built. With a phraseset, there can be 1000 phrases in a phraseset, and so in this example, there are only 1003 files to manage (.phraseset file, one .java file, one Java .class file, and 1000 audio files).

Phrasesets also support referencing audio files stored on an external server.
