Text to Speech
The Text to Speech tool converts written text into spoken audio using your browser's speech synthesis capabilities. Paste or type text, select a voice and language, and click play to hear the text read aloud. This tool is useful for proofreading, accessibility, language learning, listening to articles, and anyone who prefers audio over reading. It works entirely in your browser with no external services.

Frequently Asked Questions
Which voices are available?
Available voices depend on your browser and operating system. Most systems include several voices for major languages. Chrome and Edge offer cloud-based voices with high quality. Check the voice dropdown for available options.
Can I adjust the speed and pitch?
Yes. The rate (speed) control lets you speed up or slow down the speech (0.5 to 2.0). The pitch control adjusts the voice pitch (0 to 2.0). Slower rates are useful for language learning; faster rates for quick listening.
How long can the text be?
Most browsers can handle texts up to about 32,000 characters. For longer texts, split them into sections. Very long texts may cause the browser to pause or stop. The tool processes text in chunks for better reliability.
Can I download the audio?
The Web Speech API does not directly support audio download. To save the audio, use a screen recorder or a dedicated TTS service that offers MP3 export. This tool is designed for real-time listening, not file generation.
Is text-to-speech useful for accessibility?
Yes. TTS is essential for users with visual impairments, reading difficulties, or those who prefer audio content. It is also useful for proofreading (hearing errors you might miss when reading), language learning (pronunciation), and multitasking (listening while doing other things).
