Yayın Prosodic, morphological and lexical feature extraction of Turkish broadcast news data(Işık Üniversitesi, 2014-06-05) Revidi, İzel D.; Güz, Ümit; Işık Üniversitesi, Fen Bilimleri Enstitüsü, Elektronik Mühendisliği Yüksek Lisans ProgramıSentence segmentation from speech is part of a process that aims at enriching the unstructured stream of words that are the output of standard speech recognizers. Its role is to find the sentence units in this stream of words. Sentence segmentation is a preliminary step toward speech understanding. Once the sentence boundaries are detected, further syntactic and/or semantic analysis can be performed on these sentences. Usually, speech recognizer output lacks the textual cues to these entities (such as headers, paragraphs, sentence punctuation, and capitalization). However, speech provides extra non-lexical cues, related to features like pitch, energy, pause and word durations as prosodic features; verb, noun or adjective as a morphological features and also lexical features. These prosodic, morphological and lexical features are provides a complementary information for segmentation of speech into sentences. Our goal is examine feature the extraction and use of prosodic information which has been done in previous works, in addition to lexical features and morphological for spoken language processing of Turkish with open source tools.
