Research ArticleOpen accessPhrase in the titleSpeech Signal Analysis in Phase DomainHusne Ara Chowdhury, Mohammad Shahidur RahmanSpeech signal analysis based on the Phase Spectrum (PS) in the recent years becomes more popular to the researchers due to its attractive properties. Though some problem arises during its processing but appropriate modification gives the useful result. In this study, we proposed a new method of speech signal analysis based on its phase spectral representation. After analyzing the PS … …Journal of Computer Science, Vol. 16, Issue 8 · 10 Aug 2020 · 6,737 accessesView PDFCite
Research ArticleOpen accessIn the keywordsSpeech Enhancement Algorithm Using Sub band Two Step Decision Directed Approach with Adaptive Weighting factor and Noise Masking ThresholdDeepa Dhanaskodi, Shanmugam ArumugamProblem statement: Speech Enhancement plays an important role in any of the speech processing systems like speech recognition, mobile communication, hearing aid. Approach: In this work, human perceptual auditory masking effect is incorporated into the single channel speech enhancement algorithm. The algorithm is based on a criterion by which the audible noise may be masked rather than being attenuated and … …Journal of Computer Science, Vol. 7, Issue 6 · 14 Jun 2011 · 7,126 accessesView PDFCite
Research ArticleOpen accessIn the keywordsEffects of Noises on the Analysis of Fundamental Frequency Contours for Thai SpeechSuphattharachai ChomphanProblem statement: In speech communication, noises from surrounding environments affect the communication quality with various aspects. The received speech quality should be analyzed to see how the important noises reduce the speech quality so that we can eliminate them in an appropriate way. Approach: This study presents a study on the analysis of the noise effects on Thai speech. Four … …Journal of Computer Science, Vol. 7, Issue 4 · 4 Apr 2011 · 6,827 accessesView PDFCite
Research ArticleOpen accessIn the keywordsQuality Evaluation of Reconstructed Biological SignalsMikhled Alfaouri, Khaled Daqrouq, Ibrahim N. Abu-Isbeih et al.This research presents the use of wavelet transforms for reconstructed signal evaluation for biological signals. The method adapted on this research, is a new modeling technique and based on calculating the reconstruction error of the wavelet transform sub-signals that have different frequency bands and different deformation degree. The paper processes a special set of application in biomedical field, called Electrocardiogram … …American Journal of Applied Sciences, Vol. 6, Issue 1 · 31 Jan 2009 · 9,107 accessesView PDFCite
Research ArticleOpen accessIn the keywordsPerformance Comparison of Sub Phonetic Model with Input Signal ProcessingDr E. Ramaraj, E. ChandraThe quest to arrive at a better model for signal transformation for speech has resulted in striving to develop better signal representations and algorithm. The article explores the word model which is a concatenation of state dependent senones as an alternate for phoneme. The Research Work has an objective of involving the senone with the Input signal processing an algorithm … …Journal of Computer Science, Vol. 2, Issue 7 · 31 Jul 2006 · 6,291 accessesView PDFCite
Research ArticleOpen accessIn the keywordsSpeech Compression for Noise-Corrupted Thai Expressive SpeechSuphattharachai ChomphanProblem statement: In speech communication, speech coding aims at preserving the speech quality with lower coding bitrate. When considering the communication environment, various types of noises deteriorates the speech quality. The expressive speech with different speaking styles may cause different speech quality with the same coding method. Approach: This research proposed a study of speech compression for noise-corrupted Thai expressive … …Journal of Computer Science, Vol. 7, Issue 10 · 6 Aug 2011 · 6,230 accessesView PDFCite
Research ArticleOpen accessIn the keywordsAn Arabic Text-To-Speech System Based on Artificial Neural NetworksGhadeer Al-Said, Moussa AbdallahProblem statement: With the rapid advancement in information technology and communications, computer systems increasingly offer the users the opportunity to interact with information through speech. The interest in speech synthesis and in building voices is increasing. Worldwide, speech synthesizers have been developed for many popular languages English, Spanish and French and many researches and developments have been applied to those … …Journal of Computer Science, Vol. 5, Issue 3 · 31 Mar 2009 · 7,368 accessesView PDFCite
Research ArticleOpen accessIn the keywordsAnalysis of Speech Processing Strategies in Cochlear ImplantsKouachi Rouiha, Djedou Bachir, Bouchaala AliCochlear implants can restore partial hearing to profoundly deaf people; the main function of these prostheses is to electrically stimulate the auditory nerve using an electrode array inserted in the cochlea. The acoustic signal is picked up by a microphone and analyzed. Then the extracted parameters of the signal are coded to generate electrical signals reconstituting the original signal. Currently … …Journal of Computer Science, Vol. 4, Issue 5 · 31 May 2008 · 6,839 accessesView PDFCite
Review ArticleOpen accessIn the abstractSpeech Corpora for Different Languages: A Systematic ReviewVladimir Igorevich Fedoseev, Anton Aleksandrovich Konev, Natalia Sergeevna RepyukThe study of speech signals relies on carefully curated audio recordings, which are compiled and stored within specialized speech corpora. This article provides a comprehensive overview of such corpora across multiple languages, with particular focus on Russian, English, and Arabic. It notes that Russian and Arabic are represented by fewer corpora compared to the more extensive resources available for English. … …Journal of Computer Science, Vol. 22, Issue 1 · 2 Feb 2026 · 1,781 accessesView PDFCite
Research ArticleOpen accessIn the abstractResearch on Deep Neural Network for Afaan-Oromo Language Text-to-Speech SynthesisDiriba Gichile Rundasa, Arulmurugan Ramu, Teshome Debushe Adugna et al.Text-to-speech synthesis is the automatic translation of unlimited natural language sentences from Text to spoken form that closely mimics the spoken form of the same Text by a native speaker of the language. The purpose of a Texttext-to-speech synthesizer is to generate comprehensible, natural signalling human voice from text transcriptions. Despite the wide range of potential applications for Text-to-speech systems, … …Journal of Computer Science, Vol. 21, Issue 5 · 14 Apr 2025 · 7,346 accessesView PDFCite
