This Sound Pack is similar to the Default Text to Speech pack, but is much less verbose. Some of the notifications have been disabled entirely, such as the notifications when somebody changes channels outside of your own channel. Other notifications have been shortened to a minimal level of chattiness -- channel joins just say "John Smith joined", for example.
This pack is also set as editable, so you can edit the speech messages or re-enable any disabled notifications directly from the
Settings->Options->Notifications screen. Just double click an entry to change it.
