Semi-Automatic Segmentation System for Syllables Extraction from Continuous Arabic Audio Signal
نویسندگان
چکیده
The paper describes a speaker independent segmentation system for breaking Arabic uttered sentences into its constituent syllables. The goal is to construct a database of acoustical Arabic syllables as a step towards a syllable-based Arabic speech verification/recognition system. The proposed technique segments the utterances based on maxima extraction from delta function of 1st MFC coefficient. This method locates syllables boundaries by applying the template matching technique with reference utterances. The system was applied over a data set of 276 utterances to segment them into their 2544 constituent syllables. A segmentation success rate of about 91.5% was reached. Keywords—Arabic speech syllables; automatic segmentation; boundaries detection; delta-MFCC features

Automatic Segmentation of Wave File
This paper presents an ASS (Automatic Speech Segmentation) Technique to segment spontaneous speech into syllable like units. In the development of a syllable-centric ASS system, segmentation of the acoustic signal into syllabic units is an important stage. In this paper we focus on the identifying minimum unit of speech to be considered while training any speech recognition system. There are sy...

This paper provides an analysis of phrase and word boundary detection in a background of noise, which occurs in the context of Automatic Recognition System (ASR) and TextTo-Speech (TTS) synthesis systems for Indian languages. ASR and TTS are the major components in Speech To Speech Translation (STST) system. Both are always need a speech signal to be segmented into some basic units like phrases...
متن کاملEffect of Natural Background Noise and Man-Made Noise on Automated Frog Calls Identification System
Frog identification based on their calls becomes important for biological research and environmental monitoring. However, identifying particular frog calls becomes challenging particularly when the frog calls are interrupted with noises either in natural background noise or man-made noise. Hence, an automatic identification frog call system that robust in noisy environment has been proposed in ...
