Metaphor Solutions has released three free apps that let you interact with your phone by speaking rather than tapping. SayNCall VoiceDialer lets you call someone just by speaking his or her name, company name, or phone number. SayNFind lets you speak your destination address, and it gives you the route and driving directions. You can also ask for a category of business, and it will give you information regarding nearby establishments. SayMedia lets you speak the name of a movie or TV show and then listings, previews, and details. The company says that the apps use the most accurate speech recognition engine available.
