One of Swype keyboard's most glaring omissions, especially apparent to those of us with Android 2.1/2.2 is the missing voice input button.
The voice input button, present on the stock keyboard when typing in any text field, lets you utilize Android's speech-to-text capabilities and works surprisingly well. I sure missed it when I installed Swype.
The good news is: Swype has been listening, and the voice input button is coming soon.
They have already added it to the Swype that comes pre-loaded with the Galaxy S, as evident from the screenshot below (screenshot credit: engadget) and Droid X (screenshot credit: swype.com), so the public version is not too far off.
So, stay put, folks. You have asked and you shall receive.
