Research ArticleOpen accessEvery word in the titleImprovement of Tone Intelligibility for Average-Voice-Based Thai Speech SynthesisSuphattharachai Chomphan, Chutarat ChompunthProblem statement: Tone intelligibility in speech synthesis is an important attribute that should be taken into account. The tone correctness of the synthetic speech is degraded considerably in the average-voice-based HMM-based Thai speech synthesis. The tying mechanism in the decision tree based context clustering without appropriate criterion causes unexpected tone neutralization. Incorporation of the phrase intonation to the context clustering … …American Journal of Applied Sciences, Vol. 9, Issue 3 · 24 Jan 2012 · 6,969 accessesView PDFCite
Research ArticleOpen accessIn the abstractAN ENHANCED ROUTE FAILURE RECOVERY MODEL FOR MOBILE AD HOC NETWORKSP. R. Jasmine Jeni, A. Vimala Julie, A. Messiah BoseIn Mobile Ad Hoc Networks (MANET), change in topology of the network occurs due to the mobility factor of the nodes leading to the extension in size of the network. The extension of network size happens due to the entry of nodes into the network. As the topology changes, link failure between the nodes takes place due to several reasons … …Journal of Computer Science, Vol. 10, Issue 8 · 8 Apr 2014 · 6,730 accessesView PDFCite
Research ArticleOpen accessIn the abstractStructural Modeling of Fundamental Frequency contour for Thai TonesSuphattharachai ChomphanProblem statement: In Thai, tone is an essential feature of a prosodic syllable to identify the meanings of that syllable or that part of word. To generate the tonal speech with natural prosody, it is needed to manage the fundamental frequency (F0) of the speech appropriately. A successful approach of structural modeling from Mandarin Chinese has been adapted to model … …American Journal of Applied Sciences, Vol. 9, Issue 10 · 25 Aug 2012 · 7,122 accessesView PDFCite
Research ArticleOpen accessIn the abstractMultimodal Biometrics using Feature FusionK. Krishneswari, S. ArumugamProblem statement: Biometric is a unique, measurable physiological or behavioral characteristic of a person and finds extensive applications in authentication and authorization. Fingerprint, palm print, iris, voice, are some of the most widely used biometric for personal identification. To reduce the error rates and enhance the usability of biometric system, multimodal biometric systems are used where more than one biometric … …Journal of Computer Science, Vol. 8, Issue 3 · 24 Jan 2012 · 7,370 accessesView PDFCite
Research ArticleOpen accessIn the abstractImproving Triple Play Services Using Multi Protocol Label Switching TechnologyWaheed Yasin, Hamidah IbrahimProblem statement: Traditional IP networks have many limitations such as routing tables, which can be complex and time consuming. These limitations affect the performance of the network in some applications of triple play services (i.e., voice, video and data) which are characterized as time sensitive applications. Thus, Multi Protocol Label Switching (MPLS) technology has been proposed to speed up the … …Journal of Computer Science, Vol. 6, Issue 3 · 31 Mar 2010 · 7,520 accessesView PDFCite
Research ArticleOpen accessIn the abstractSpeaker Recognition Using Spectral Cross-correlation: A Fast AlgorithmZoubir HamiciThis study presents an original algorithm for computing the cross-correlation function applied for speech recognition A spectral correlation estimation algorithm based on the comparing the magnitude spectrum of the two signals is presented. The number of samples is reduced by a factor of two, after eliminating the image spectrum. A moving average filter is used to smooth the magnitude spectrum … …Journal of Computer Science, Vol. 1, Issue 2 · 19 Oct 2005 · 5,013 accessesView PDFCite
Research ArticleOpen accessAll words, across the recordSpeech Segmentation Using Dynamic Windows and Thresholds for Arabic and English LanguagesYahia Hasan JazyahSegmentation of audio data such as human speech (splitting each word in separate audio file – .WAV file) has been a major concern when working with multimedia such as recordings from radio or TV. The main focus of the segmentation of boundaries of spoken language has been on using energy and zero crossing thresholds for endpoint detection. Errors in endpoint … …Journal of Computer Science, Vol. 14, Issue 4 · 18 Apr 2018 · 7,778 accessesView PDFCite
