Özet

The sudden increase of the workload and transaction speed in daily life forced humans to develop new technologies to adapt these situations. One of these technologies is the complex software that transform text into speech. This study aims at developing a phoneme/phone-based text-to-speech software, which does not need large databases, and which can run on different platforms. To achieve this, the phonological structure of Turkish was investigated and then a phoneme/phone-based textto-speech software is developed, differently from most of the previous studies. At the end of the study, a software that runs with a small database is developed. Since the rules, symbol and recordings used in the algorithm are kept separately from the code of the software, it allows to change these data without altering the code. Thus, it would not be necessary to write the code anew for future improvements. The powerful morphology of Turkish, and the complex morphology-phonology interaction prevented processing of prosodic features such as stress and intonation. To perform such a processing, a large and annotated database is needed to conduct morphological and syntactic parsing. Considering these limitations of our study we believe that the software we developed runs smoothly, however it requires improvement regarding prosody.
