It may have taken Google a year and a half to get Google Voice in the iPhone's App Store, but it's taken only one month longer for Google Voice to complete the expansion to Apple's other two iOS devices: the iPod Touch and iPad.

Starting today, a Google Voice app update compatible with the iPad and iPod Touch (iOS 3.1 and above) will make it easier for U.S. users to manage voice messages and texts made to your Google Voice number.

Of course, it can't place calls on either of these nonphone devices, but a click-to-call feature will let you initiate a call on a phone associated with your Google Voice account.

Google has made other improvements that will benefit iPhone users, too, including one that will automatically keep the service from texting your iPhone and your Google Voice inbox when you sign on. Receiving duplicate notifications to the phone text inbox and the Google Voice app was an early complaint of mine.

In addition, a new "do not disturb" feature will send all calls to voice mail, and tapping and holding a text will now give you the option to archive or delete it. 

In the past month since I've been using Google Voice on iPhone I've loved the convenience of the app, but have experienced sluggishness when it loads, some navigation lag, and oftentimes delayed incoming texts and voice mails. What's your experience?

True story: The other day I was looking up onomatopoeia on Dictionary.com (don't ask.) Let's just say I didn't quite get all my vowels lined up right the first time; trial and error ensued.

Next time, I won't have to toil so for my vocab payoff. A new voice search feature on Dictionary.com, releasing today for iPhone and Android, will let you speak your search term into the app.

This is a boon for anyone voted least likely to win a spelling bee, or for anyone else who prefers to skip the typing.

Voice-to-text shows up in the app as a separate function on a separate screen. This isn't a bad interface decision, but placing it on the search bar as Google does its Android search widget would make it much more accessible.

In addition to voice search, the update let you revisit definitions in a list of favorites. It also brings a feature where you can click a word to get a definition, customizable backgrounds, and for word nerds, sharing on social networks.

Dictionary.com has been downloaded over 20 million times on the iOS, Android, and Blackberry platforms. The updates will surely make the app richer on the former two; we hope BlackBerry users have a chance to benefit as well.
