Quite good, but could use some improvements
This is way better than the built-in voice features in OSX, given that it enables you to immediately see where you are in a document, as well as stop and start when you want (a glaringly missing feature in the OS). However, it stumbles in that the maximum playback speed is 235 words per minute -- slower than the maximum speed provided by the operating system -- which limits the usefulness of this program. In addition to support for HD Voices (like whats available in Lion), this app could also be improved by adding an export feature, so that people can export their audio recordings to iTunes to add to their iPods for listening on the go. Im really looking forward to when an app comes along that will allow all of this. I think it would be a blockbuster!
