As a translator I would like to have my voice masked so that I cannot be recognized by my voice, yet the recording is clear to the hearer.

From Doug Schreiber... We've been on a long quest to find voice masking software for doing oral BT here in China, a secure access country. It is risky for the minorities to do the recording lest they be found out and persecuted in some way.

I've worked with a brother in SIL here to identify potential apps. The most promising (and expensive) was FLUX but I found it took a very powerful PC to work (more than my SurfacePro3) and the masking was not quite what I had hoped for - especially for $300+. I found it also a bit difficult to figure out how to tune the voices, etc. other than using the presets.

I happened upon AV Voice Changing Software Diamond. (http://www.audio4fun.com http://www.audio4fun.com/) for $100*. I first tried it myself by masking my own voice then sending it to my family. Since it sounded a lot like my sister so I pretended that it was a podcast of someone who sounded like my sister and asked them to confirm. They fell for it. The quality is not crystal clear and sounds a bit tinny (sample attached), like over a cell phone, but they didn't know it was me. I created the attached manual and gave it to the Pomegranate team to test and they agreed that it appears to be decent.

Though we have not started using in production, I wanted to get it out there in case there were others in similar situations who have been requesting help. If you want to refer them to me for more info., I'd be glad to help as I can.

*I searched online and found a $25 discount; not sure it if's still available.
