Online Demos

  The demos constitute applications that illustrate the strength of the IITM approach to multilingual computing on the web. These demos show the capabilities of the applications which are based on the syllable level coding employed for representing text in a uniform manner across the scripts. The demos clearly establish the viability of multilingual computing and localization of applications. The text to speech features are also illustrated in the demo pages. 

   Notable among the demos are the Akshara Animation page and the Search Engine application. Examples are shown for searches in the text of Bhagavadgita or Tirukkural

   The demo on online text to speech synthesis shows how speech can be synthesized using MBROLA. Speech synthesis is illustrated for Sanskrit as well as Tamil.

Unicode Test Pages

 The main strength of the Multilingual Software developed at the lab is the approach to working with Indian languages at the level of syllables. This approach results in very efficient representation of text in terms of fixed length codes for syllables which can also be quickly converted to other representations such as Unicode or ISCII. The service provided here allows one to submit text in any of the scripts and get a  web page containing Unicode representation of the text.
