I don't know of any way to "echo" your voice on Windows Movie Maker. At least, there isn't a feature in the program that can do that anyway.
The only thing I can suggest is to add an echo to your voice using an external voice/audio editor. Then import the audio into Windows Movie Maker.
As far as I know, you can't put an echo on clips in Windows Movie Maker. If you want an echo, you would need to use an external audio editor to produce the effect first, then import the file into the program afterwards.
Rehanfx has many plug-in effects for Windows Movie Maker. You should check the site out to search for an echo effect:http://www.rehanfx.org/

Echo did not have any known powers. She could only echo what people said because of Hera's curse on her, but that is not a special power.
