Yahoo has added voice search capabilities to their Yahoo Mobile 1.1 for iPhone and iPod Touch. Google already added voice recognition to their iPhone search application on November last year.

“You’ll press the oneSearch field and see the large gray button prompting you to press and speak your inquiry,” CNET writes, adding that like most voice input systems, this one isn’t without its computational errors — especially in recognizing voice accurately.

Other features in YM version 1.1 including:

• Instant Messaging
• Share Photos
• Stealth Settings
• Custom status message
• Recent conversations archive
• Special idle state
• Landscape keyboard mode
• New “Report a Problem” feature
