In this article we present the variation of the speech signal of the database TIMIT and NTIMIT with its morphological characteristics of the speakers as well as the extrinsic variability related to the conditions of transmission and acquisition of the signal. For this study we measured the timbre and the intensity in order to choose the best indices that give us a good effect for the identification...
A Unit Selection based Synthesis (USS) system selects appropriate units from the inventory based on target cost and join cost. For a syllable based USS system, it is not practically feasible to cover all possible syllables in a language with all possible contexts. Hence, some discontinuity is observed at the concatenation points in the synthesized speech due to unavailability of units with proper...
Speech is the most basic and widely used method for communication. There is a growing need for an expressive speech synthesis especially, when human want to communicate with robots and computers. In this paper, prosody rule-sets are designed to convert neutral to storytelling style speech for Hindi language. In order to generate a storyteller speech from a neutral speech, modification in various prosodic...
In recent years, the work on expressive styles of speech has increased rather than focusing on basic emotions. The present paper shows the comparison of expressive speech and neutral speech on the basis of pitch and intensity where neutral speech can be further modify to produce expressive style with emotion which is suitable for story telling application. Our approach is to perform an analysis of...
In this paper, the average intensity and the effect of focus and stress on it for disyllabic words in Chinese is analyzed. The key words in the experiment are 20 verbs, occurring in sentence medial position, and the subjects are eight native speakers of standard Chinese. Average intensity is analyzed, and results show that the intensity of the rhyme is greater than that of the onset. The effect of...
Word boundary detection in continuous speech is very common and important problem in speech synthesis and recognition. Several researches are open on this field. Since there is no sign of start of the word, end of the word and number of words in the spoken utterance of any natural language, one must study the intonation pattern of a particular language. In this paper an algorithm is proposed to detect...
This article presents a technique that uses the intensity vector direction exploitation (IVDE) method for exhaustive separation of convolutive mixtures. While only a four-element compact sensor array is used, multiple channels for all possible source directions are produced by exhaustive separation. Singular value decomposition (SVD) is then applied to determine the signal subspace and the directions...
