US search giant Google on Monday launched a Chinese version of its voice search service for mobile phones for a market with at least 700 million mobile users.

The service is available for the Nokia S60 phone in China's mainland, Taiwan, Hong Kong and Macao. A query of an address in Mandarin Chinese could return a result within seconds.

Google launched multi-language voice search engines to overcome the difficulty of typing complicated search queries on mobile phones, said Lin Bin, deputy head of Google's China research center.

Google offered its English voice search service, including images and maps, for the Android, Nokia S60, BlackBerry and iPhone phones last year.
