About Text-to-Speech
This tool uses the Web Speech API built into modern browsers to read text aloud. Choose from all available system voices, adjust the speaking speed (0.1x to 3x), and modify the pitch. You can pause and resume playback at any time. The number of available voices depends on your operating system and browser — desktop browsers typically offer more options than mobile. All processing happens locally on your device using the browser's built-in speech synthesis engine. Perfect for proofreading text, accessibility support, language learning, or listening to articles while multitasking.
How Browser-Based Text to Speech Works
This tool uses the Web Speech API — a browser standard supported by Chrome, Edge, Safari, and Firefox — to convert text to speech entirely on your device. Unlike cloud-based TTS services, there are no API calls, no file uploads, and no processing on external servers. Your text stays completely private and conversion is instant because everything runs locally.
The available voices depend on which voices are installed on your operating system and browser. Windows, macOS, and mobile platforms each come with different built-in voices, and many support multiple languages. Chrome and Edge typically offer the widest selection.
Practical Uses for Text to Speech
- Proofreading — listening to your own writing reveals awkward phrasing and errors that reading misses.
- Accessibility — converts written content to audio for people with reading difficulties or visual impairments.
- Language learning — hear the correct pronunciation of words or sentences in a foreign language.
- Multitasking — listen to articles, notes, or documents while doing other tasks.
- Content creation — preview how a script sounds before recording a voiceover.
- Studying — convert study notes to audio and listen while commuting or exercising.
Tips for Better TTS Output
- Slow the speech rate down for complex or technical content — easier to follow at 0.8× speed.
- Add commas to create natural pauses where the synthesized voice rushes through text.
- Spell out abbreviations for cleaner pronunciation — "AI" reads as "A.I." if not spelled out.
- For numbers, write them as words for more natural delivery in non-technical contexts.

What voices are available?
Available voices depend on your browser and operating system. Most modern browsers provide multiple voices in different languages and accents. You can select your preferred voice from the dropdown.
Can I adjust the speech speed?
Yes. You can adjust both the speed (rate) and pitch of the speech using the provided controls. This is useful for proofreading at faster speeds or for language learning at slower speeds.
