Item IMPLEMENTATION OF TURKISH TEXT TO SPEECH SYNTHESIS WITH RC8660 VOICE SYNTHESIZER(2015-10-25) KARAMEHMET, Timur; TORA, Hakan; USLU, İbrahim BaranThis thesis examines the text-to-speech (TTS) synthesis problem and the adaptation of the RC8660 Embedded System to Turkish. RC8660 is a system loaded with English phonemes and in the thesis the aim is to make this card synthesize Turkish. Firstly Turkish phonemes from their corresponding English phonemes are defined. For this purpose IPA: International Phonetic Alphabet was used. Because the syllabic structures of Turkish and English are different, there occurred a need for defining an Exception Dictionary using the text and phoneme modes of the system. The rules for correct syllabification were added to the dictionary one by one. Stress and intonation rules were also defined for making the synthesized Turkish speech as natural as a native speaker’s. Different phonemes were used for text and alphanumeric characters. The effects of the Speed, Expression, Pitch, Formant Frequency, Tone, Delay, and Articulation adjustments in the system’s software: RC Studio were also tested on the speech. The quality of the synthesis was evaluated by the Mean Opinion Score (MOS) test.
