On-line Demos of multilingual applications
  Welcome to this page devoted to the display of Multilingual applications developed using the IITM software. The applications are divided into different groups as follows.

1. Data entry and on-line transliteration
2. Conversion utilities and Animation
3. Search Applications  (includes an online dictionary)
4. Text to speech output
5. Bharati Braille
6. Generate Unicode test pages

  The demos have been setup to give you an idea of the capabilities of the software while presenting at the same time, a truly web based user interface. Many of the demos are one of a kind and it is quite unlikely that there are matching demos elsewhere. The applications shown here clearly demonstrate the power of syllable level coding of the Aksharas of Indian languages.

  Almost all the demos will run on standard browsers which can handle gif images and java applets. There is no need to have special fonts or software running on your system. Only those demos which explicitly relate to html output will require you to install the IITM supplied fonts. See comment on the right.

Multilingual displays
View the text of " Vande Mataram " in the script of your choice.

  This application presents an interface for you to select the script in which the text of Bankim's immortal "vande mataram" is to be displayed. This demo also serves to illustrate direct transliteration across scripts.

On-line transliteration between scripts.

  Demo allows you to enter text in Devanagari but view it transliterated into other scripts.


Conversion Utilities and animation
View Indian language text in different  output formats

  The purpose of this demo is to illustrate the text processing capabilities of the software to provide output in different formats for direct display on the web.

On-line transliteration from Roman to Indian scripts.

  Demo illustrates the capability built into IITM software to convert from Roman transliteration into the respective Indian scripts.  You can enter text in ITRANS and view the result in different scripts and two different output formats. The ability of the system to send the contents of a text file in the desired script as well as in different formats assures one that text can be seen on virtually any browser supporting graphics. The on-line lessons on Learning Sanskrit have been seen all over the world on account of the standardized format understood by all browsers.

Akshara animation 

How each vowel and consonant is written (stroked) 

Devanagari and Tamil

Conversion of text into Bharati Braille

  Demo to illustrate how text prepared in Indian scripts may be immediately converted to Bharati Braille. 

Unicode test pages

  Use this demo to generate Unicode text of your choice and view the same on your browser. This demo will be useful for checking the rendering of Unicode text by your browser. All the nine scripts supported in Unicode may be tried. You will also be able to get an idea of the versatility of the IITM approach to dealing with Indian language text.


Search Applications
  These demos are applications involving a search engine for archives of Indian language text. Use the demo to locate text strings in Gita and Kural. The application also serves to provide concordances. Search results are returned in html format and hence the recommended IITM fonts must be present in your computer. However, an alternate view through graphic images is also provided if you do not have the required fonts.

The prescribed set of fonts are included with the Multilingual Editor package distributed freely from this web site.

Search the text of  Gita        Search the text of Tirukkural

View an on-line Sanskrit dictionary

  The famous Monier Williams Dictionary is presented at this web site to interactively look up meanings of words in Sanskrit. Display is in Devanagari as well as Roman. Search strings may be entered in Devanagari (using the applet based interface) or Roman using a transliteration scheme (Harvard Kyoto scheme).


Text to Speech output
  The Multilingual Systems project at IIT Madras has resulted in many useful  applications for the Visually Handicapped. These applications take advantage of the text to speech capabilities built into them. The freely distributed MBROLA speech engine is used in synthesizing speech in all the applications. The demos below are representative of the quality of speech output with the existing applications. While sounding a bit robotic and lacking intonation, the speech output has been found to be very acceptable to Visually Handicapped users. A separate page is devoted to the discussion of text to speech applications.
Examples of text to speech output are included in the linked page. Audio files in Real Audio format and some in mp3. Requires Real Audio player and a suitable player for mp3.

On-line text to speech synthesis.

Enter a short sentence in Sanskrit or Tamil and hear it, as synthesized by the IITM Text to speech software. This is a java applet. Requires a player for wave files (.wav format).

Note on the demos

The demos shown in these pages will work with web browsers which support

Display of graphic images
Java applets
Dynamic fonts
Multimedia (Audio)

Some of the demos use the html format to display results in Indian scripts. It may be necessary for viewers to check that the prescribed fonts are installed in their systems or that the Dynamic Font rendering capability is active in the browser.

Java Applets

Demos involving Java Applets are known to work properly with Netscape (4.7 or later), Mozilla, Firefox, Opera and IE (6.0). Strangely, we have not been able to get them to work on an Apple Mac. It appears that applet behaviour is influenced by the Java Runtime Environment.

The temples of Kerala are unique in providing rows of lamps on the outer walls. The perspective is striking!
