[Emacspeak] Re: Emacspeak on Android

[codeofdusk@xxxxxxxxxxx]

I think the Astro Slide might be a really interesting Emacspeak device, especially if the dual-boot Linux supports native audio and if someone wrote an Emacs package for handling calls/SMS when in Linux...

Very Nice!

I suspect tweaking buffer-size will give you most bang for the buck; Are you using Outloud or Espeak?

Once you get this tuned to your liking, I'd request you write it up as a simple org file and post it somewhere; I'd also like to include it in the emacspeak distribution when the write-up is ready.
