Troubleshooting TTS Not Working
When Built-in TTS Is Not Enough
Text to speech (TTS) is built into every major operating system, but activating it is rarely obvious. The setting is usually buried inside Accessibility menus, and the exact path differs on every platform. This guide gives you the exact steps for iPhone, Android, Windows, and Mac — plus a quick troubleshooting section if the feature is not responding.

On iPhone

iPhone has two separate TTS features, both found under Settings > Accessibility > Spoken Content.

Speak Screen

Speak Screen reads everything visible on the screen when you swipe down from the top with two fingers.
  1. Open Settings
  2. Tap Accessibility
  3. Tap Spoken Content
  4. Toggle Speak Screen to on (green)
  5. From any screen, swipe down from the top edge with two fingers — a playback bar will appear

Speak Selection

Speak Selection adds a "Speak" option to the text selection menu so you can hear only the text you highlight.
  1. Open Settings
  2. Tap Accessibility
  3. Tap Spoken Content
  4. Toggle Speak Selection to on
  5. Select any text in any app → tap Speak in the popup menu
You can also adjust the speaking rate and choose different voice packs under Voices in the same Spoken Content menu.

Quick Tip: On iPhone, you can trigger Speak Screen at any time by swiping down from the top of the screen with two fingers — no need to open Settings again once the feature is enabled.

On Android

Android's TTS setting is located in the Accessibility menu, though the exact label and path vary slightly by manufacturer (Samsung, Google Pixel, OnePlus, etc.).

Stock Android (Google Pixel)

  1. Open Settings
  2. Tap Accessibility
  4. Choose your Preferred engine (Google Text-to-Speech is the default)
  5. Tap Listen to an example to confirm TTS is working
To activate TTS while reading, select text and look for a "Read Aloud" or "Speak" option in the text selection menu — availability depends on the app.

Samsung Galaxy (One UI)

Samsung devices have an additional feature called Voice Assistant (Screen Reader), which is different from general TTS output. For document or web-page reading, follow the same path:
  1. Open Settings
  2. Tap Accessibility
  3. Tap Hearing enhancements or Text-to-Speech (varies by One UI version)
  4. Tap Text-to-speech output
  5. Set Preferred engine and adjust speech rate and pitch as needed

On Windows

Windows offers two TTS tools: Narrator (full screen reader) and Select-to-Speak / Read Aloud in Microsoft Edge.

Narrator

  1. Press Windows + Ctrl + Enter to toggle Windows Narrator on and off
  2. Narrator will immediately begin reading the active window
  3. To configure voices: open Settings > Accessibility > Narrator > Narrator's voice

Select-to-Speak (Windows 11)

Windows 11 includes a "Read aloud" feature in Edge and a system-wide Select-to-Speak option:
  1. Open Settings > Accessibility > Narrator
  2. Enable Narrator and configure as needed
  3. For a lighter option: in Microsoft Edge, open any article or PDF, right-click, and select Read aloud

Quick keyboard shortcut

Press Windows + Ctrl + Enter to toggle Narrator at any time without opening Settings.

On Mac

Mac's TTS feature is called Spoken Content and lives in System Settings.

Enable Speak Selection

  1. Open System Settings (macOS Ventura and later) or System Preferences
  2. Go to Accessibility
  3. Click Spoken Content
  4. Toggle Speak selection to on
  5. The default keyboard shortcut is Option + Esc — press it while text is selected to hear it read aloud

Enable Speak Screen

  1. In the same Spoken Content panel, toggle Speak screen to on
  2. Use the shortcut Option + Esc (or the custom shortcut you set) to read the entire screen
To change the voice: click System Voice and choose from the available options. You can download premium voices by clicking Customize.

Troubleshooting TTS Not Working

If text to speech is enabled but nothing plays, work through these checks:
On all platforms:
  • Make sure your device volume is turned up and not set to silent
  • Check that the TTS voice pack is downloaded — many devices require an internet connection to install voices the first time
  • Restart the app you are reading in
On iPhone:
  • Go to Settings > Accessibility > Spoken Content and confirm the toggle is green
  • Try selecting a short word, then tap Speak in the popup
On Android:
  • Go to Settings > Accessibility > Text-to-Speech Output and tap "Listen to an example"
  • If nothing plays, switch the preferred engine to Google Text-to-Speech and try again
On Windows:
  • Open Narrator Settings (Settings > Accessibility > Narrator) and confirm it is toggled on
  • Check that the selected voice is installed — click "Add voices" if the list is empty
On Mac:
  • Go to System Settings > Accessibility > Spoken Content
  • Click the System Voice dropdown and confirm a voice is selected
  • Press Option + Esc while text is highlighted to test

When Built-in TTS Is Not Enough

System TTS works well for short passages, but it has real limits: robotic voices, no document import, no speed syncing, and no cross-device history. If you regularly listen to long articles, PDFs, newsletters, or web content, AI Listen is worth exploring.
AI Listen is an iOS app designed specifically for long-form audio reading. It supports natural-sounding AI voices, lets you import documents and URLs directly, and remembers your listening position across sessions. It is a practical upgrade over the built-in Spoken Content feature on iPhone — especially if you listen for more than a few minutes at a time.
Built-in TTS is the right starting point. For anything more demanding, AI Listen fills the gaps system tools leave behind.
