Automatic Reading from Bangla PDF Document Using Rule Based Concatenative Synthesis

Abstract

In this paper we present a rule based concatenative method for Bangla text to speech conversion. Here our target is to generate almost natural speech from Bangla PDF text. For this we have proposed a speech synthesizer, which performs two major tasks. One is PDF to unicode text conversion and another is unicode text to speech conversion. We use text normalization and parsing rules to get syllables which give us scope to produce natural speech. We have analyzed the proposed method and an existing method with respect to time complexity and compared the performance of the methods.
