# Text-to-Speech Not Working? Complete Troubleshooting Guide & Solutions Published: February 4, 2026 · Author: Deepak Gupta Text to speech not working? The cause is almost always one of 5 things. It's the sound output, a speech setting or missing voice data, a recent update, a dropped connection to a cloud voice, or the text itself. Check them in that order. Most problems are fixed in the first 2 steps, without reinstalling anything. *Last updated: October 6, 2026. Settings paths were checked against Microsoft, Google and Apple support pages on that date.* This guide is for anyone whose computer, phone, video editor or online voice tool has stopped reading text aloud, or reads it badly. Start with the quick checks, then jump to your device.

Key Takeaways

Start with sound, not software. Volume, mute, the selected output device and speaker setup cause many "silent" TTS problems.
Missing voice data stops speech. If a language's voice isn't installed on Windows or Android, the device can't read that text.
Updates can break things, and later updates fix them. Install the latest updates instead of disabling security settings.
Long or messy text causes errors. Symbols, very long inputs and unpunctuated text can make an engine fail, cut out or mash words together.
Run a "Hello world" test. If a short, plain sentence plays, your settings are fine and the original text is the problem.

Match what you see to a row, then try the first fix.

Cause	What you notice	First fix
Sound output	Silence, or a voice that is very quiet or muffled	Check volume, mute and the selected output device; set speakers to stereo
Settings or missing voice data	Nothing plays for one language, or the feature is off	Turn the speech feature on and install the voice for that language
Software update or conflict	TTS stopped right after an update	Install the latest updates, then restart
Connection to a cloud voice	Timeouts, long waits, audio that stops halfway	Check your internet connection, sign out and back in, try again
The text itself	Errors on one script only, garbled words, cut-off audio	Remove symbols, add punctuation, split long text

## Quick checks first These take a minute and solve a large share of problems.

Quick checks: tick each one as you go

Work from top to bottom. Stop at the first one that brings the voice back.

Check volume and mute. Look at the system volume, the app's own volume and any hardware mute switch.Check the output device. Make sure sound is going to the speakers or headphones you are using, not a disconnected device.Close apps that hold the audio. Video calls, games and music apps can take control of the sound device.Run the "Hello world" test. Paste "Hello world." into the same app. If it plays, your text is the problem; skip to the text section.Restart the app, then the device. A restart clears stuck audio and speech services.

## Fixing TTS on Windows Windows uses its own speech voices for Narrator and for many apps that read text aloud. ### Turn on Narrator and add voices 1. Press the Windows logo key + Ctrl + N to open Narrator settings. 2. To add a modern voice, select **Add** under **Add natural voices** and pick a voice to download. 3. For older apps, select **Add legacy voices**, then **Add voices**, and choose the language you need. If one language never speaks, the voice for that language is usually not installed. Microsoft lists which languages have voices in its Narrator support pages. ### Fix silent or muffled speech - **Set speakers to stereo.** Windows may think you have 5.1 surround sound when you use stereo speakers or a laptop. Then voices mixed into the center channel can go quiet or vanish. - **Turn off audio enhancements** in the sound device's properties if speech sounds distorted. - **Update or reinstall the audio driver** from Device Manager if a yellow warning icon appears. ### Text to speech stopped after a Windows update Updates sometimes break features that later updates fix. For example, after the October 11, 2022 updates, Microsoft confirmed some SSL and TLS connections could fail. Out-of-band updates on October 17, 2022 (KB5020435 for Windows 10, KB5020387 for Windows 11) addressed it. Cloud voices rely on those secure connections, so install the latest updates first. Earlier versions of this guide suggested disabling TLS 1.3 to work around timeouts. We no longer recommend that, because it weakens your connection security. ## Fixing TTS on Android 1. Open **Settings**, then **Accessibility**, then **Text-to-speech output**. 2. Check the **preferred engine**, the **language**, the **speech rate** and the **pitch**. 3. Press **Play** to hear a short sample. If it plays, the engine works. 4. If a language is missing, choose **Install voice data** and download it. 5. Still silent? Clear the cache of the speech engine app in **Settings > Apps**, then restart the phone. Some apps also need permission to play audio in the background. If speech stops when the screen turns off, check the app's battery and background settings. ## Fixing TTS on iPhone and iPad 1. Go to **Settings > Accessibility > Spoken Content**. 2. Turn on **Speak Selection** to hear text you select, or **Speak Screen** to hear the whole screen with a two-finger swipe down from the top. 3. Open **Voices**, choose a voice and make sure it has finished downloading. 4. Use **Pronunciations** to fix a word your iPhone keeps saying wrong. 5. Turn the ring or silent switch off, check the volume and restart the device.

That adds 3 new failure points: the connection, your account and limits on how much text one request can take. - **Timeout errors.** The tool waited for audio that never arrived. Check your connection, then try a shorter piece of text. - **Sign-in problems.** Sign out of the tool's account and back in to refresh your session. - **Text length limits.** Many tools limit how much text you can send in one request. Check your tool's limit and split long scripts into smaller parts. - **Credits or plan limits.** Online voice tools meter usage. If generation stops, check whether you've used your monthly allowance. - **Browser issues.** Allow sound for the site, disable extensions that block scripts, or try a different browser.

Check your connection and free storage space, then retry. If it keeps failing, remove the voice and download it again. ## When the text is the problem If the "Hello world" test works but your script fails, the text is the cause. Flow diagram for a failing script: check for special characters and length, clean the text, split it into chunks, test a simpler format and check which app has audio focus.

Try it: clean a script that fails

Copy this messy line, paste it into the tool that failed, and note what goes wrong. Then compare it with the fixed version in the table below.

Tea & cake + a chat, it's 100% worth it says Saoirse

| What was wrong | Before | After | |---|---|---| | Symbols | Tea & cake + a chat | Tea and cake and a chat | | Percent sign | 100% | 100 percent | | Hard name | Saoirse | Sur-sha | | No end punctuation | ...says Saoirse | ...says Sur-sha. | - **Write out symbols.** Replace "&", "%", "+" and math symbols with words such as "and" and "percent". - **Split long text.** Very long inputs can time out or make a voice run words together. Generate one paragraph at a time. - **Add punctuation.** End every sentence and list item with a period so the voice knows where to pause. - **Check the language.** The voice must match the language of the text. A voice for one language may skip or garble words in another. - **Fix pronunciation errors in the text.** Spell hard names the way they sound, for example "Sur-sha" for "Saoirse".

Usually the speech feature is off, the volume is muted, or the voice for your language isn't downloaded. On Android, check Settings > Accessibility > Text-to-speech output. On iPhone, check Settings > Accessibility > Spoken Content. ### Why does text to speech sound muffled or robotic? Muffled speech often comes from a speaker setup mismatch, such as 5.1 surround on stereo speakers. Robotic delivery usually comes from the text: long sentences, missing punctuation or symbols. Fix the audio setup first, then the script. ### Why does text to speech stop partway through long text? Many tools limit how much text one request can take, and long requests can time out. Split the text into paragraphs and generate them one at a time. ### Why won't text to speech read my language? The device or tool needs a voice for that language. Install the language's voice data on your device, or choose a tool that has voices for it. ### Is speech to text not working the same problem? No. Speech to text turns your voice into text, so it depends on the microphone and microphone permissions. Text to speech depends on speakers, speech settings and voice data. ### How do I fix TTS pronunciation errors? Spell the word the way it sounds, add punctuation around it, or use your device's pronunciation settings. On iPhone, use the Pronunciations option in Spoken Content. ## How we checked this guide This guide is written by Deepak Gupta for the [Kveeky](https://kveeky.com/) team. **Disclosure: Kveeky makes an AI voice generator.** Settings paths come from the platform makers' own support pages: - Windows Narrator voices: [Microsoft Support, Supported languages and voices](https://support.microsoft.com/en-us/accessibility/windows/narrator/appendix-a-supported-languages-and-voices), retrieved 2026-10-06. - The October 2022 TLS issue and fix: [Microsoft KB5020387](https://support.microsoft.com/en-us/servicing/os/windows-11/2022/10/october-17-2022-kb5020387-os-build-22000-1100-out-of-band) and [Microsoft KB5020435](https://support.microsoft.com/en-us/servicing/os/windows-10/2022/10/october-17-2022-kb5020435-os-builds-19042-2132-19043-2132-and-19044-2132-out-of-band), retrieved 2026-10-06. - Android: [Google Android Accessibility Help, Text-to-speech output](https://support.google.com/accessibility/android/answer/6006983), retrieved 2026-10-06. - iPhone: [Apple iPhone User Guide, Spoken Content](https://support.apple.com/guide/iphone/hear-iphone-speak-the-screen-iph96b214f0/ios), retrieved 2026-10-06. - Kveeky plan details: [Kveeky pricing](https://kveeky.com/pricing/), retrieved 2026-10-06.
