How can I customize the speech on the 7330?

The 7330 has a built-in library of about 1,600 words that were created by professional announcer Sean Caldwell (  In addition, custom recordings of words and phrases can be created. The 7330 has storage for up to 2,000 additional sound files totaling 13 minutes of playback time. 

You can contract with Sean if you want additional words or phrases in the same voice as the built-in vocabulary (he's a ham and offers favored pricing to 7330 owners). Or, you can create your own words with a PC and a sound editor such as Audacity. The resulting files are loaded into the controller via the serial port. So, you can end up with a combination of Sean's words and your own, and you can record over Sean's words if you wish. 

Of course, stringing together words sounds somewhat mechanical and never sounds quite as good as recording entire sentences. Many customers record their announcements using local talent; 13 minutes is plenty of recording time to inform listeners about hamfests, meetings, dues, nets, and so on. Chapter 23 of the 7330 User's Manual has instructions for using Audacity.  Here is a web site with additional tips for using Audacity and SoX to create voice prompt files.
