I just got the festival text to speech package working with Raspbian (updated to latest packages 15-08-2012) - It sounds pretty good and says any text or text file I give it. I want to use it for a user interface, giving feedback to buttons pressed and status reports etc. on a Pi without display.If anyone has more experience with Festival text to speech could you give some tips to these problems I have:1) After saying a word or sentence, Festival needs a pause of approximately 5 seconds before accepting more text, otherwise I get an 'audio device not available' error. Is there a way to shorten this delay or to terminate the Festival/audio process?2) Is it possible to use a different voice e.g. female3) Can the speed of speech be changed - slower or faster?
I didn't find the right solution from the internet.
