We incorporated severalstate-of-the-art technologies into this system, including theSpeech Transformation and Representation using Adaptive Interpolationof weiGHTed spectrum (STRAIGHT) vocoder, minimumgeneration error (MGE) training, phone duration modeling,parameter generation algorithm considering global variance,and linear spectrum pair (LSP)-based formant enhancement.The runtime of system synthesizes speech around 0.3xRT (real time ratio), and its footprint is less than 25 MB. Theresults of listening tests showed that the overall speech qualityand intelligibility of our systems are better than most othersystems, especially when we have better labeling for a speechcorpus., The Blizzard Challenge 2009 workshop was held 4th September 2009, at the University of Edinburgh.}, publisher = {Speech Synthesis Special Interet Group}, title = {Overview of NIT HMM-based speech synthesis system for Blizzard Challenge 2009}, year = {2009}, yomi = {オオウラ, ケイイチロウ} }
