Vocaroo is a web-based service which allows you to record your own voice and to publish it online or send it to someone via email.
Vocaroo is as simple as it can get. You click on the Record button and hit Stop when you are done. Your recording is immediately available, for email forwarding or for being embedded on any web site.
The recording is also available for immediate download in both .WAV and .Ogg audio formats.
Vocaroo is in beta and is free to use.
