After doing what little research I could, it being a new device aimed for a very small number of people overall, I decided to give VoiceZam a try. If you hear from me over the next few days/weeks/decades, you may get a VoiceZam link in addition to/instead of a website link. It will be keyed up to the appropriate demo for you, all broken out by spot so you can find the voice you like quickly. At least, that's the hope. I'll check in after testing it out for a few weeks.
UPDATE 1 - Here's my ZamLink. It promises to make life better. I love that I can update the player and anything with the link will be automatically updated as well.
