You can do lot of interesting stuff with Google Talk. Such features can be easily integrated into Google Talk through ‘bots’ which, in simple English, are like virtual friends who are online 24×7 and will always respond with a smile to your questions or requests.

Examples:

Translation - This is a free service from Google that helps you translate words from a foreign language into your native language. Just add the relevant bot (e.g. hi2en@bot.talk.google.com for Hindi to English or en2hi@bot.talk.google.com for English to Hindi) as your buddy, send him a message and it will get translated instantly.

Transliteration - If you want to chat in your mother tongue (like Hindi or Tamil) but feel more comfortable using the English keyboard, Google Transliteration bot will come in handy.

For instance, add en2hi.translit@bot.talk.google.com to you friend’s list in GTalk and all messages you type in English will get transliterated in the language of your choice. Available only for a few Indian languages.
