How to Enable Microsoft Copilot Voice on Microsoft 365 Mobile App

You want to use voice input with Copilot on the Microsoft 365 mobile app instead of typing queries. Copilot Voice lets you speak prompts naturally, and the feature replies with spoken answers while also showing text in the chat. This article explains the requirements and shows you exactly how to turn on voice mode in the iOS and Android apps. You will learn where the voice button is, how to grant microphone permission, and how to switch between text and voice interaction.

What the Copilot Voice Feature Does on Mobile

Copilot Voice on the Microsoft 365 mobile app allows you to speak queries instead of typing. The feature uses the device microphone to capture your speech, sends it to Microsoft servers for transcription and AI processing, and then plays back the spoken response through the device speaker. The response also appears as text in the chat transcript for reference.

The voice feature works with any Copilot skill available in the mobile app, including summarization, content generation, and question answering. It does not require a separate subscription beyond your existing Copilot for Microsoft 365 license or Copilot Pro subscription. The feature is available in all languages that Copilot supports for text input.

Prerequisites for Using Voice

Before you can enable voice, confirm the following:

• You have the Microsoft 365 mobile app installed from the iOS App Store or Google Play Store.
• The app version is 16.0.17328.20000 or newer. Check your version in Settings > About Microsoft 365.
• You are signed in with a work or school account that has a Copilot for Microsoft 365 license, or a personal Microsoft account with Copilot Pro.
• Your device has a working microphone and is not in silent mode or Do Not Disturb mode.

Steps to Enable Copilot Voice on the Microsoft 365 Mobile App

Follow these steps exactly. The process is identical on iOS and Android except for the permission prompt appearance.

1. Open the Microsoft 365 mobile app
   Launch the app on your iPhone, iPad, or Android device. Make sure you are signed in with your work or school account or personal Microsoft account.
2. Tap the Copilot icon
   Find the Copilot icon at the bottom-center of the screen. It looks like a purple or blue chat bubble with a sparkle symbol. Tap it to open the Copilot chat interface.
3. Locate the microphone button
   In the Copilot chat window, look at the bottom of the screen. Next to the text input field, you will see a microphone icon. If you do not see it, your app version may be outdated. Update the app from your device store.
4. Tap the microphone button
   Tap the microphone icon. A permission dialog will appear asking for microphone access. Tap Allow or OK on the dialog. On iOS, you may need to go to Settings > Privacy > Microphone and toggle Microsoft 365 to On if you previously denied access.
5. Speak your query
   After granting permission, the microphone button will turn blue or become highlighted. Speak your question or command clearly. For example, say “Summarize the latest quarterly report from finance.” Copilot will process your speech and display the response as text. The app will also read the response aloud if your device volume is on.
6. End the voice session
   Tap the microphone button again or tap the Send icon to stop recording. You can also press the keyboard icon to return to text input at any time.

Common Issues When Enabling Copilot Voice

Microphone button is missing

If the microphone button does not appear, your app version is likely below 16.0.17328.20000. Update the app through the iOS App Store or Google Play Store. If you already have the latest version, sign out and sign back in to force a refresh of the app configuration.

Voice input is not recognized

Copilot may fail to transcribe your speech if the microphone is blocked by a case or if background noise is too high. Move to a quiet location. On Android, check that no other app is holding the microphone exclusively. Close apps like voice assistants or video recorders before using Copilot Voice.

Copilot does not speak the response

Voice output depends on your device media volume. Increase the volume using the physical buttons on your device. Also check that your device is not in silent mode. On iOS, ensure the silent switch on the side of the phone is not set to silent. On Android, verify that Do Not Disturb is turned off.

Permission keeps resetting

Some Android devices revoke microphone permission for apps that are not used frequently. Open your device Settings > Apps > Microsoft 365 > Permissions and set Microphone to Allow only while using the app. On iOS, the permission should persist once granted. If it resets, reinstall the app.

Copilot Voice vs Text Input: Key Differences

Item	Voice Input	Text Input
Input method	Speak into device microphone	Type using on-screen or physical keyboard
Response type	Spoken audio plus text transcript	Text only
Speed of input	Faster for long queries	Slower for long queries
Privacy concern	Audio sent to Microsoft servers for processing	Text sent to Microsoft servers for processing
Supported languages	Same as text input languages	All Copilot-supported languages
Device requirement	Working microphone and speaker	Keyboard input

You can now enable Copilot Voice on the Microsoft 365 mobile app and switch between voice and text input as needed. Try using voice for longer prompts like “Draft an email to the team about the project deadline extension” to see the speed benefit. For quick yes-no questions, text input remains faster because you skip the permission prompt. Remember that voice responses require your device volume to be on, so adjust it before starting a session.
