Speech Server

Screen Reader TTS Service

Develop a simple and scalable Screen Reader TTS Service for (Text to Speech) Plugin using eSpeak Speech synthesis for XO using python.

The Screen reader will provide the users with the following capabilities :

A TTS Control Panel to control various parameters of ESpeak.
Ability to highlight text anywhere, and synthesize speech from it using a keyboard shortcut or through a button in Sugar UI.
A panel to modify the speech parameters like words/min, language, gender, pitch , volume etc.
Providing ability to user to save their preferences and retrieve them after system reboot.
Providing the user ability to load the default settings for the speech service.
Providing the user a play button which would play the highlighted text, and change to a stop button to asynchronously stop playback.
Providing a parallel activity using the underlying speech server. The activity will allow kids to type in a text box and use the speech server capabilities. Allowing the kid to experiment with the speech parameters can be an extremely interesting activity for them. For example increasing the rate of speaking wordw along with the pitch will yield a very interesting voice which the kids (may) find funny.

A dbus service to expose the espeak object globally to all xo activities.
a python script to accept highlighted data from sugar environment using X11 Primary selection and pass it to the dbus service for synthesis.
