I want to send messages on LINE using voice input!

To send LINE messages by voice input, all you need to do is turn on the voice input function on your iPhone, iPad, or Android smartphone and tap the microphone icon on the keyboard.

This article provides a detailed, screenshot-guided explanation of how to send messages on LINE using voice input, from setup to the actual input process.

※This guide uses screenshots from iOS 18 for iPhone and Android 12 for Android smartphones.

How to Set Up Voice Input (iPhone/Android)

To use voice input for LINE messages, you first need to enable the voice input function on your smartphone.

How to Set Up Voice Input on iPhone/iPad

To enable voice input on your iPhone or iPad (iOS), first open the "Settings" app.

From the "Settings" app, open "General".

Select "Keyboard".

In "Keyboard," turn ON "Enable Dictation".

Now, your iPhone/iPad is ready for voice input.

How to Set Up Voice Input on Android Smartphone

To enable voice input on your Android smartphone, first open the "Settings" app.

Scroll down the "Settings" app and select "System" at the bottom.

Next, open "Languages & input" within "System."

On the "Languages & input" screen, select "On-screen keyboard".

Opening "On-screen keyboard" will display a list of currently installed keyboards. Select the keyboard you normally use (in this case, "Gboard" was selected).

On the keyboard settings screen, select "Voice typing."

On the opened screen, turn ON voice typing.

Now your Android smartphone is ready for voice input.

※Please note that the setup method may vary depending on the keyboard app you are using on your Android smartphone.

Steps to Send Messages on LINE with Voice Input

Once the settings are complete, let's try voice inputting into LINE.

Voice Input on LINE with iPhone

On the LINE message screen, select the message input field to open the keyboard.

Tap the microphone icon at the bottom left of the keyboard.

If "Enable Dictation?" appears, select "Enable Dictation".

A microphone and "あ" (Japanese character) icon will appear in the input field, indicating that voice input is ready.

When you speak into your iPhone or iPad's microphone in this state, your spoken words will be transcribed like this.

Tap the send button to send the transcribed content.

Tapping the microphone icon at the bottom left of the keyboard again will end voice input.

Voice Input on LINE with Android Smartphone

On the LINE message screen, select the message input field to open the keyboard.

Tap the microphone icon at the top right of the keyboard.

※Tap the microphone below the one on the right side of the LINE input field, not the one directly on the right.

Be careful not to confuse it with the microphone on the right of the input field, which is for "voice messages" (a function to send audio as is).

"Speak now" will be displayed, indicating that voice input is ready.

When you speak into your Android smartphone's microphone in this state, your words will be transcribed as shown.

Tap the send button to send the transcribed content.

Tapping the microphone button again or tapping another button will end voice input.

Troubleshooting When Voice Input Doesn't Work

If voice input isn't working on LINE, check the following points:

Voice Input Setting is OFF

For iPhone/iPad, check if "Settings" → "General" → "Keyboard" → "Enable Dictation" is ON.

For Android smartphones, check if "Settings" → "System" → "Languages & input" → "On-screen keyboard" → your current keyboard → "Voice typing" is ON.

LINE App Microphone Permission Not Granted

For iPhone, check if "Settings" → "LINE" → "Microphone" is ON. For Android, check if "Settings" → "Apps" → "LINE" → "Permissions" → "Microphone" is allowed.

Tapping the Wrong Microphone Icon

LINE has two microphone icons.

The microphone on the keyboard is for voice input (text conversion), and the microphone to the right of the input field is for voice messages (sending audio).

When you want to use voice input, tap the microphone on the keyboard.
