Type text by speaking
You can use voice input to type text by speaking. This feature uses Google's speech-recognition service,
so you must have a data connection on a mobile or Wi-Fi network to use it.
Text that you enter by speaking is underlined. You can continue entering text to keep it, or delete it.
You can speak to enter text in most places that you can enter text with the onscreen keyboard.
1 Touch a text field, or a location in text you've already entered in a text field.
2 Touch the Microphone key on the onscreen keyboard.
3 When you see the microphone image, speak what you want to type.
Say “comma", "period", "question mark", "exclamation mark" or "exclamation point” to enter
punctuation.
When you pause, what you spoke is transcribed by the speech-recognition service and entered in the
text field, underlined. You can touch the Delete
key to erase the underlined text. If you start typing or entering more text by speaking, the underline
disappears.
