How to Use Text-to-Speech in Microsoft Office: Read Aloud Guide for Word, Excel, Outlook and PowerPoint

Microsoft Office includes a powerful text-to-speech feature called Read Aloud that can read your documents, emails, spreadsheets and presentations out loud. Whether you need to proofread a report, multitask while reviewing emails, or improve accessibility, this built-in tool works across Word, Excel, Outlook, PowerPoint and OneNote -- and you do not need any third-party software.

Below is a complete guide to using text-to-speech in every major Office application, including Read Aloud, Speak and Immersive Reader.

Read Aloud vs Speak: What Is the Difference?

Microsoft Office actually has two text-to-speech features, and they work differently:

Recommendation: For most users, Read Aloud is the better choice because it highlights words as they are spoken, making it easier to follow along and catch errors.

How to Use Read Aloud in Microsoft Word

Word offers the most complete text-to-speech experience in the Office suite. Here is how to activate it:

Method 1: From the Ribbon

1. Open your document in Microsoft Word.
2. Click the Review tab in the ribbon.
3. Click Read Aloud in the Speech group.
4. Word begins reading from the cursor position. Each word is highlighted as it is spoken.
5. Use the playback toolbar to pause, skip forward, skip back, change speed or switch voices.

Method 2: Keyboard Shortcut

Press Alt + Ctrl + Space to toggle Read Aloud on or off instantly. This is the fastest way to start listening.

Method 3: Right-Click

Right-click anywhere in your document and select Read Aloud from the context menu. Word reads from that point onward.

Using Speak for Selected Text

1. Select the text you want to hear.
2. If you have not added Speak to your Quick Access Toolbar yet, go to File > Options > Quick Access Toolbar.
3. In the Choose commands from dropdown, select All Commands.
4. Scroll to Speak, select it, and click Add.
5. Now select any text and click the Speak icon in your toolbar.

How to Use Text-to-Speech in Excel

Excel does not have the Read Aloud button in the ribbon by default, but it offers two methods for text-to-speech:

Method 1: Immersive Reader

1. Open your spreadsheet in Excel.
2. Go to View > Immersive Reader.
3. Excel displays your data in a reading-friendly layout.
4. Click the Play button to hear the content read aloud.
5. Adjust speed and voice settings as needed.

This is particularly useful when you need to verify data entry -- listen to cell values while comparing them against a paper document.

Method 2: Speak Cells Command

1. Add the Speak Cells commands to your Quick Access Toolbar (File > Options > Quick Access Toolbar > All Commands).
2. Look for: Speak Cells, Speak Cells - Stop Speaking Cells, Speak Cells by Columns, and Speak Cells by Rows.
3. Select a range of cells and click the Speak icon to hear their contents.

How to Use Read Aloud in Outlook

Read Aloud in Outlook is perfect for listening to emails while multitasking. It works in both the reading pane and when composing messages.

1. Open an email in Outlook.
2. Click the Home tab (or Message tab if composing).
3. Click Read Aloud in the Speech group.
4. Outlook reads the email content, highlighting each word.

Tip: In Outlook for the web and mobile, Read Aloud is available under the three-dot menu (...) > Immersive Reader.

Text-to-Speech in PowerPoint

PowerPoint supports the Speak command (via Quick Access Toolbar) for reading selected text on your slides. This is helpful when rehearsing presentations or checking text for errors.

1. Add Speak to your Quick Access Toolbar (same method as Word above).
2. Select text on any slide.
3. Click the Speak button to hear it read aloud.

Note: Read Aloud with full playback controls is not available in PowerPoint. For a richer text-to-speech experience during presentation prep, paste your slide notes into Word and use Read Aloud there.

Using Immersive Reader for Enhanced Reading

Immersive Reader goes beyond basic text-to-speech. It is a full reading environment built into Office that includes:

• Read Aloud with word-by-word highlighting
• Text spacing adjustments for easier reading
• Syllable breakdown to help with pronunciation
• Parts of speech highlighting (nouns, verbs, adjectives)
• Line focus to reduce visual distraction
• Page colour customisation to reduce eye strain

Immersive Reader is available in Word, Excel, Outlook, OneNote and Microsoft Teams. To access it, look for the book icon under the View tab.

This feature is invaluable for users with dyslexia, visual impairments or reading difficulties, as well as anyone learning a new language or reviewing lengthy documents.

How to Customise Voice, Speed and Language

When Read Aloud is active, you can fine-tune the experience:

• Speed: Use the speed slider in the Read Aloud toolbar. Choose from 0.5x (slow) to 2x (fast).
• Voice: Click the voice dropdown to choose from available voices. Options vary by operating system. Windows 11 includes natural-sounding neural voices in multiple languages.
• Language: Read Aloud automatically detects the language of your text. To add more voices, go to Windows Settings > Time & Language > Speech and download additional voice packs.

Adding More Voices on Windows

1. Open Settings > Time & Language > Speech.
2. Under Manage voices, click Add voices.
3. Select the languages you need (French, German, Spanish, Italian, Portuguese and many more are available).
4. These voices then appear in the Read Aloud dropdown in Office.

Troubleshooting Common Issues

Read Aloud Button Is Greyed Out or Missing

• Make sure you are using Office 2019, 2021, 2024 or Microsoft 365. Read Aloud is not available in Office 2016 or earlier.
• Check that your Office installation is up to date (File > Account > Update Options).
• Ensure your document is not in Compatibility Mode (.doc format). Save as .docx.

No Sound When Using Read Aloud

• Check your system volume and audio output device.
• Verify that a text-to-speech voice is installed: Settings > Time & Language > Speech.
• Try selecting a different voice in the Read Aloud dropdown.

Read Aloud Skips Text or Reads Incorrectly

• Text inside images, charts or SmartArt is not read. Only plain text and table content are supported.
• Heavily formatted text (e.g., text boxes overlapping) may be read out of order.

Which Office Versions Support Text-to-Speech?

If you are using Office 2016 or earlier, you only have access to the basic Speak command. For the full Read Aloud experience with playback controls and word highlighting, you need Office 2019 or later.
