I have not tested your patch on my Archos V1 because I don't have an up
to date development environment, but would like to say something about
the following comment at your above link:-

When I played around with this some time ago, I found that the MAS MP3
decoder would hiccup and loose one or two syllables when transitioning
between talkbox clips and Voice UI clips.

I found that this could be cured by ensuring that similar Lame
parameters were used for encoding both the .talk files and the Voice UI.
The parameters actually used were quite different, as the Voice UI
required that the clips were as short as possible so that the packed
module would fit into the available memory.

I hope that you find this information helpful.
