| dc.description.abstract | the field of T ext-To- Speech (TIS) synthesis is one in which much development and research has taken place over the last few decades. As a result of advances made, many laboratory and commercial systems of high quality exist today. This thesis is an attempt made to develop a prototype TIS system for the Tigrigna language. It is based on the concatenation of dip hoes using TD-PSOLA (Time-Domain Pitch Synchronous Overlap and Add) technique. I used my voice to record an inventory of speech from which dip bone units were extracted. The Tigrigna text to speech system has two major distinct pans, which are text processing followed by speech synthesis . Visual C++ prograrnmig language is used to develop anointer face and to handle text processing and MA1LAB prograramming ( language is used to handle the signal processing. Two major activities were made while preparing the diaphone database; careful selection of corpus words and extraction of diaphones from these words. To record corpus wocds and then to extract diaphones from these words the free software called Prate is used For testing this system ; the Mean Opinion Score (MOS) testing method was adopted And the average result Computed was found to be 3.05, which is closer to scale level good I e. 3. fu system is a good start to introducing realistic speech from text, but there are several areas that can be improved Inclusions of acronym converter to the text processing moclule and prcsody control are some of the things that need father research | en_US |
