If you use the command "Say" in AFL, or some other kind of audio alerts, check this site out;
http://www.research.att.com/~ttsweb/tts/demo.php
This site lets you type in the text, listen to it, and download it. Easy and painless. You can select different voices as well. It sounds tons better than other text to speech engines I've heard, and it sure beats the basic voice Microsoft gives you (Amibroker uses the Microsoft engine when you call the "say" function, look it up in AFL help)
I use the "Lauren" voice to tell me all about the orders I submit, or if there are data errors, etc. Why stop there? You can use these sounds as part of your windows sounds scheme too.
So when you boot up your computer after dinner to plan the day for tomorrow, this is what you could hear.
