In the last decade there has been a shift towards development of speech synthesizer using concatenative synthesis technique instead of parametric synthesis. There are a number of different methodologies for concatenative synthesis like TDPSOLA, PSOLA, and MBROLA. This paper, describes a concatenative speech synthesis system based on Epoch Synchronous Non(More)
Bangla phoneme inventory consists of 32 consonants out of those 16 are stop or plosive and 4 are affricate. This paper presents the detailed investigation of place and manner of articulation of Bengali phonemes. The place of articulation study of consonants is based on Electropalatography (EPG) system and the manner of articulation study is based on(More)
Control of pause occurrence and duration is an important issue for text-to-speech synthesis systems. In text-readout speech, pauses occur unconditionally at sentence boundaries and with high probability at major syntactic boundaries such as clause boundaries, but more or less arbitrarily at minor syntactic boundaries. Pause duration tends to be longer at(More)
Pronunciation dictionary is one of the important components for the speech technology development for a particular language. This is because it represents the interface between speech analysis on the acoustic level and speech interpretation. The W3C Voice Browser Activity has published a Pronunciation Lexicon Specification (PLS) Version 1.0 [1] for(More)
This paper describes the method of generation of intonated speech for natural speech synthesis using prosody generation model. The effect of pitch modification through pitch contour stylization for parameter extraction and time scale modification for it’s implementation has been mentioned. An approach for close-copy syllabic stylization has been described.(More)
English speech of L1 English and L1 Bengali speakers of the same discourse is analyzed by applying hierarchical discourse prosody framework HPG (Hierarchy of Prosodic Phrase Group) in order to find the between-and within-group similarities and differences in speech planning of L1 (native) and L2 (non-native) English speakers for prosodic organization at(More)
