<div dir="ltr">Hi Nurendra,<div>Certainly there are many thinks we can do connected with text to speech.</div><div>We use the "espeak" [1] utility, included in the linux distributions,</div><div>and a gstreamer plugin to use it from python.</div><div>Text to speech is used in many activitieas, and also in Sugar itself,</div><div>you can select any text and press a icon in the frame or press a shortcut</div><div>and the text is played. You can see the code here [2]</div><div>We call that "Global text to speech" [3] </div><div>Right now, I want move part of that code to the toolkit (the library shared by Sugar,</div><div>and the activities, to avoid code duplication) [4] </div><div><br></div><div>Where we can get help?</div><div>* Better voices: espeak is very robotic.There are other free voices with better quality?</div><div>Can be used in devices with modest capabilities like the xo? </div><div><br></div><div>* I found a project on debian repository to compile svox-pico,</div><div>used in Android. The voices are very nice, but I don't know if is possible distribute it.</div><div>You can compile it in Fedora doing:</div><div><div><br></div><div>git clone -b upstream+patches git://<a href="http://git.debian.org/collab-maint/svox.git">git.debian.org/collab-maint/svox.git</a> svox-pico</div><div>git checkout -f origin/debian-sid</div><div>cd pico</div><div>./autogen.sh</div><div>./configure</div><div>make </div><div>make install</div></div><div><br></div><div>And can create a wav file wih the text doing:</div><div><br></div><div>pico2wave --wave=/tmp/test.wav "hello world"<br></div><div><br></div><div>To be able to use this, we would need package all this are rpms,</div><div>and create a gstreamer pluggin to use it.</div><div>Not so easy, but a nice project ;)</div><div><br></div><div>* Other project could be improve our text to speech feature to be able </div><div>to highlight word by word while are played, like in "sing along" videos [5]</div><div>At least in part was implemented on Read activity when reading text files,</div><div>but need implementation in PDF and epub files.</div><div>I tried implementing in epub files but was very slow and lost sync between </div><div>the audio and the view.</div><div class="gmail_extra"><br></div><div class="gmail_extra">There more things to do if you are interested.</div><div class="gmail_extra">We found text to speech is a powerful tool.
