T-Scribe for Android
This app takes advantage of Android's voice recognition capability. Being nearly deaf, sometimes there are words and phrases that I just cannot understand no matter how many times they are repeated. I had people write them down on paper, but now they just speak into my phone and the words appear.
I have found I use T-Scribe for many other functions - remembering names, phone numbers, and appointments. I also use the quick "copy to clipboard" ability to preload words and phrases (my email addess for example) for pasting into other apps.
The latest version also lets you change the text font size.
