Now search is just a call. Google has set path for a new era in the speech analytics with 'voice search', which it recently introduced in Hyderabad, Delhi, Mumbai and Bangalore. One just needs to speak a single word into the phone, such as 'whether' or 'hotel' and one can get the top results.
Currently, the automated system offers results in English, but the operator-driven system offers results in only Hindi and Telegu.
Google's logic is a simple one. Mobiles outnumber personal computers (PCs) in India. Besides, just about 5-7 percent of the population has an internet connection, including those who use surf the net via their mobiles. Source.
