Speech Recognition and Speech Synthesis

Possibilities, in the areas of speech recognition and synthesis for developing a voice enabled translation system for Indian Languages, which can be used for telephonic chatting, querries, reading eMail are also being explored.

VACHANTAR -Rajbhasha

The Vachantar, a speech-to-text translation system requires the following two major components:

  • A Speech Recognition Engine
  • A Source Language to Target Language Translation Engine

    The user communicates with the application through the appropriate input device i.e. a microphone. The Recognizer converts the analog signal into digital signal for the speech processing. A stream of text is generated after the processing. This source-language text becomes input to the Translation Engine, which converts it to the target language text.

    The Vachantar-Rajbhasha system takes English speech as an input and produces Hindi Text as an output. The system recognizes the English speech after the corrected English text goes for translation through MANTRA-Rajbhasha Translation system and produces Hindi Text as an output

    On 14th September 2007 Vachantar- Rajbhasha Beta Version has been released. Vachantar-Rajbhasha will released after getting the feed back from the user.
