For several years I have been experimenting with voice-to-text software for my students who have difficulty writing for themselves. The students who need it the most had very little success with it! Well, actually I didn’t have success with it, either. I would say something and it would insert so many errors that it would have been faster to just type it myself!
And, then.....along came a free app (Dragon Dictation) for iPod Touch, iPhone, and iPad that works great. I downloaded the app, dictated several sentences, and the software translated it to text perfectly! (Your device needs a microphone to allow you to record, so if you have an older iPod Touch you may need a microphone you can plug in.)
It is very easy to use. When you open the app, there is a red icon in the middle of the screen that is labeled "Tap here and dictate." When you touch that and start speaking, it records up to 20 seconds of your voice. Then you select "Done," and it processes the recording and sends it back as text. You can keep adding more and more to it to create a long document if you need to. It responds to commands like "period," "comma," "exclamation mark," and "new paragraph," as well as many of the commands that their Dragon Naturally Speaking software allows. See it in action here.
If it does have an error in the translation, you can tap the screen and delete the word or open the keyboard to make the correction yourself. I encourage my students to email the document to themselves and cut and paste it into their word processor. From there, they can use text-to-speech software to listen for their errors! What a great combo!
Best of all, Dragon Dictation is free! Try it out to see if it works for your child.
