Please create the following new third_party repository:
https://chromium.googlesource.com/chromiumos/third_party/espeak-ng.  

Please clone the upstream repository from GitHub here:
https://github.com/espeak-ng/espeak-ng.git

Owners should be:

dmazzoni@chromium.org
dtseng@chromium.org
katie@chromium.org

This will enable us to ship Chromium OS with the Espeak NG speech engine to support more text-to-speech voices out of the box. We'll actually save rootfs space overall because then we won't have to ship as many high-quality voices.

Thanks!
