Amharic is the official language of Ethiopia. In this paper, we present our study on Amharic stress. Stress (Gemination of consonants) in Amharic language is very important for proper pronunciation of words. It is also one of the most distinctive characteristics of the rhythm of the speech. We discuss a method employed for generating stressed syllables from(More)
Developing correct Grapheme-to-Phoneme (GTP) conversion method is a central problem in text-tospeech synthesis. Particularly, deriving phonological features which are not shown in orthography is challenging. In the Amharic language, geminates and epenthetic vowels are very crucial for proper pronunciation but neither is shown in orthography. This paper(More)
This paper presents analysis and modeling of geminate duration in Amharic Text-to-Speech (AmhTTS) synthesis system. AmhTTS is a parametric and rule-based system that employs a cepstral method. The system uses a source filter model for speech production and a Log Magnitude Approximation (LMA) filter as the vocal tract filter. Fundamental speech units of the(More)
This paper reports preliminary results of data-driven decision tree based segmental duration prediction for Amharic Text-to-speech synthesis system. Using a manually annotated speech corpus, we extracted a limited number of important features for the construction of training and testing sets. Then, a decision tree based segmental duration prediction was(More)
