Reviewing research in TTS

This is an attempt to continue the efforts put in after the INTERSPEECH 2015 review sessions. The sessions facilitated any research student to learn the topics in an effortless manner. 2015 is the first time IIIT-H has participated in the Blizzard Synthesis Challenge and building the system was one of the most memorable experiences in my Research. In a nutshell, our submission was a Unit Selection and Contenation one with reduced vowel based epenthesis for missing syllables and word to phone mapping for English words.
