Hate pecking away on a tiny glass keyboard? While that sort of thing may be okay for texting and other short bursts of data entry, it can become wearisome when you want to process a significant amount of words.

Voice search and dictation programs have been around for a while, and both Windows and OS X have had their own speech-to-text recognition functions for years. As we all know, Google Now, Cortana and Siri all response to brief voice commands. But if you want to compose that great American Novel on the go, you can do it without having to download a third-party dictation app, thanks to built-in functions you already have on your mobile device — as long as that device is running a fairly recent version of its maker’s operating system.

Both Android and iOS include the dictation feature, but you may have to enable the service in your system settings if you start yapping and nothing happens. Also, keep in mind that in most cases, your words are being sent up to a server in the sky for translation, so manage your own privacy expectations.

In recent versions or Android, you can dictate documents in Google Docs open in the Chrome browser — and even add punctuation and editing by calling out the commands. Just open a Google Doc and either tap the microphone, or go to the Tools menu and choose Voice Typing. Then dictate your thoughts.

If you get no reaction from your Android device, do into the Settings app to Language and Input and make sure Google Voice Typing is enabled. You can tap further into the settings there to make adjustments, like activating the ability to record through a Bluetooth headset or to block any offensive words that may (accidentally, of course) slip into your speech while dictating.

On a compatible iOS device, turn on the speech-to-text feature by going to Settings > General > Keyboard. Flip on the button next to Dictation to enable it. Now, when you want to recite a lengthy bit of text in Notes, Mail or another wordy app, tap the small microphone icon that now resides on the iOS keyboard and start talking.

The dictation feature may not be as precise as an real, live human secretary, but it should get you that first draft with a minimum of actual typing. So grab your phone, yell “Take a memo!” as you tap on the microphone and start talking your typing.
