The latest Dolphin Browser update adds a host of voice control features all rolled into a system called Sonar. Sonar adds browser-specific commands to its interface, allowing for more precise touch-free control. Dolphin Sonar is part of the 7.4 release of Dolphin Browser for Android, making it easy to search the web, share links or open specific web apps and pages by speaking.
Sonar works like most voice-activated features: you tape the microphone and speak a command. What you can say to Dolphin is pretty interesting. Aside from initiating basic search commands, you can specify specific sites (like Facebook and eBay) to search within them directly. To activate Dolphin Sonar, you can shake your phone or tap on the microphone in the lower right corner.
