The use of speech recognition is fairly well implemented in WP7, being both powerful as a system function, and yet simple to use from a consumer/user perspective.
To access this feature, simply press and hold the Start button on the phone. You will in turn receive a distinct set of tones to indicate that the phone is ready to accept your voice command as input.
There are currently four basic categories for commands issued directly with the phone:
– Calling Someone from your contact list.
– Sending a Text Message
– Searching the web for keywords.
– Open an application.
List of Commands
– To Call someone from your contact list: “Call contact name” (where contact name is the name of someone in your contact list). If the person has only one phone number in your contact profile, the call will start. If he or she has multiple phone numbers, you’ll hear an option to choose one of them (usually “Mobile”, “Home”, or “Work”).
– To Call any phone number: “Call phone number” (where “phone number” is any phone number)
– To Call the last number dialed: Simply say “Redial”.
– To Call your voicemail: Simply say “Call voicemail”.
– To Send a text message: “Text contact name” (where contact name is the name of someone in your contact list). This will start a text message to that person. Then you can dictate and send the message-hands-free.
– To Open an application: “Open application” or “Start application” (where application is the name of any application on your phone, such as “Calendar,” “Maps,” or “Music”).
– To Search the web: “Find search term” or “Search for search term” (where search term is what you’re looking for). For example, if you say “Find local pizza”, Bing will bring up a map of nearby pizza
places.
You can also use Speech while you are already on a current call in order to use Additional commands.
Press and hold the Start button to start Speech while on the call, and then say one of the following:
– “Press number” (where number is a number from 0 to 9) to press a number on the numeric keypad. This allows you to navigate in voicemail or an IVR (interactive voice response) system.
– “Speaker phone” to toggle your speaker phone on or off.
– “Call name” (where name is the name of someone in your contact list) to put the current call on hold and then call someone else.
