Android 2.3 (Gingerbread) may be coming with new capabilities, but Froyo (Android 2.2) already has a feature under-utilized by most users. Google has included sophisticated voice input technology in Froyo that can turn handling an Android phone into a largely hands-free experience. This guide lays out how to get the most out of voice input on Android 2.2.
Google is synonymous with search, and Voice Search makes it easier on Android phones than on any other platform. Long-press the search button on the phone (hold the button down for a few seconds) and Voice Search fires up. You can also tap the microphone button in any search box. When the dialog box tells you to “speak now,” that’s what you do. Don’t preface your search term with anything about search; just speak the phrase you want to use in the search. When you pause your speech for a few seconds, Voice Search will convert what you’ve said into text. If it determines you’ve spoken a term for a web search, it fires up the default browser to a Google search of the term. If it detects a name in your contact list, it opens that app to the desired person.
One of the most useful functions for voice input in Android is text entry in any app. Instead of typing your text into the app’s text box, you simply speak it, and Android converts it to text and inputs it for you. This method is surprisingly accurate as long as you keep the entry short and sweet. The longer the entry, the more prone to error voice input is with the interpretation. Google handles errors smartly, however, as several interpretations of the speech are presented in a dialog box, allowing you to tap the accurate one. Using voice for text entry is as simple as tapping the microphone key on the displayed keyboard that is presented when a text entry box has the focus on the screen.
Google has enabled a variety of common functions that can be triggered by voice on Android. These run the gamut of mapping searches, navigating to locations, calling people/ businesses, sending texts/ emails and browsing to web sites. Here’s a list of voice actions (and what to say) that can be performed:
- Call contact — “Call Joe Smith Mobile” to call him on his mobile phone
- Call business — “Call Pizza Hut Cypress” to call their location in Cypress (will search for it)
- Go to web site — “Go to Wikipedia”
- View a map — “Map of Mexican restaurants in Houston”
- Navigate to location — “Navigate to 123 Main Street”
- Send text message — “Send text to Joe Smith I’m running late”
- Send email — “Send email to Joe Smith How are you? I am fine.” Format name, subject, email body
- Listen to music — “Listen to Aerosmith”. Strangely, this will only play music in certain third-party apps, not the Android music app. Apps that will work are Pandora, Last.fm and a few others.
Search Within Apps
Searching by voice works in a number of apps, and it’s worth trying in your favorite app if you often search while running it. You can search by voice in e-books in the Kindle app, although the newly released Google Books app does not support search. Google’s own Reader app doesn’t support voice search either. The trick is to try a search in your apps and see if the microphone button appears in the search box.
International travelers have a friend in Android with Google Translate installed. The app can translate between many languages so the proper phrase is always at hand. It accepts speech input making entering the phrase as easy as saying it. Translate can speak the translated phrase in some languages with the proper accent, making it a good way to find what you need while traveling abroad.
