Re: Emacspeak phrase breaks
Festival seems to be a very interesting alternative for Emacspeak
speech output. Considering the monthly increase in CPU horse power,
problems with CPU speed should resolve magically until the adaption to
Emacspeak is completed.

While Festival is a more CPU intensive speech option than Freespeech/Mbrola, the Festival option seems more stable. The Festival source is also freely available, and works on systems for which Mbrola binaries are not available (my workstation running Alpha Redhat Linux, for example).

> Raman, I'd like to know the thinking behind your strategy for breaking up chunks to be sent to the speech server. Usually, I receive entire lines from Emacspeak, but I've noticed that chunks are separated into separate chunks when a "," is encountered. Is this the only character? Is there a variable that contains all of these characters?

It seems, however, that Emacspeak usually passes entire lines as chunks, so I must not have the right idea regarding chunk breaking.

When Emacspeak is doing something similar, it creates more utterances (chunks of spoken material) than is reasonable.
