Abstract: In this paper, we investigate the use of a new continuity measure based on maximum signal correlation for optimal selection of units in concatenative text-to-speech (TTS) synthesis framework. We explore two formulations for calculating the signal correlation: cross correlation (CC) based and average magnitude difference function (AMDF) based. We first perform an initial experiment to understand the significance of the approach and then build 5 experimental systems which are available a web demo. Evaluations on 30 sentences each for Telugu and Hindi by native users of the languages show that the proposed continuity measure results in more natural sounding synthesis.
