Hi yokoy, We are developing a screen-reader application for XO. For TTS we have implemented a dbus-glib based speech-server on XO which uses espeak internally. <div class="gmail_quote"><div> The methods exposed by D-BUS will be help applications to use speech-server in a global fashion. And also this access will be very efficient as compared to calling os.system commands. You would like to check this out <a href="http://wiki.laptop.org/go/Screen_Reader" target="_blank">http://wiki.laptop.org/go/Screen_Reader</a> We are currently in the process of deciding the final speech-server API's which will take considerable amount of time. I have made some changes in your program to demonstrate how speech-server can be used by other applications for TTS. The API's used are temporary and are subject to change. To test this code first go to screen-reader/sugar-speechd and do ./sugar-speechd After this start ELIZA as usual. And this will run on XO also. </div></div>-- With Regards Assim Deodia
