Kotha : the first to speech synthesis for Bangla language
(BRAC University, 2008) Nath, Promila Kanti; Khan, Mumit
In this Thesis paper, we represent Text to Speech (কথা) synthesis system for Bangla language and how can we develop it using phonology, prosodic rules, G2P conversion including prosodic information in the Festival [1] framework. Since Festival does not provide complete language processing support for all languages, it needs to be augmented to facilitate the development of TTS Systems (কথা) in certain new language Bangla. A new language needs inputs for resolving language specific issues requiring close collaboration between linguists and technologists. Large amount of annotated data is required for developing language-processing modules like text normalization, graphemeto- phoneme (G2P), intonation, and time duration models. We propose how these modules can be develop and integrate it with Festival.
Text to speech for Bangla language using festival
(BRAC University, 2007) Alam, Firoj; Nath, Promila Kanti; Khan, Mumit
In this paper, we present a Text to Speech (TTS) synthesis system for Bangla language using the opensource Festival TTS engine. Festival is a complete TTS synthesis system, with components supporting front-end processing of the input text, language modeling, and speech synthesis using its signal processing module. The Bangla TTS system proposed here, creates the voice data for festival, and additionally extends festival using its embedded scheme scripting interface to incorporate Bangla language support. Festival is a concatenative TTS system using diphone or other unit selection speech units. Our TTS implementation uses two different kinds of these concatenative methods supported in Festival: unit selection and multisyn unit selection. The modules of such a TTS system are described in this paper, followed by an evaluation of the quality of synthesized speech for acceptability and intelligibility.

The Bangla TTS system proposed here, creates the voice data for festival, and additionally extends festival using its embedded scheme scripting interface to incorporate Bangla language support. Festival is a oncatenative TTS system using diphone or other unit selection speech units. Our TTS implementation uses two different kinds of these concatenative methods supported in Festival: unit selection and multisyn unit selection. The function of a Text-to-Speech system is to convert some language text into its spoken equivalent by a series of modules. These modules, constituting the TTS system are described in detail which is very much helpful for future development. Finally, the quality of synthesized speech is assessed in terms of acceptability and intelligibility.
