Text to Speech
Convert text to natural-sounding speech with customizable voice settings
About Text to Speech
Text to Speech (TTS) technology converts written text into spoken words using synthetic voices. This tool uses your browser's built-in speech synthesis API to provide natural-sounding audio output.
Features:
- Multiple voice options with different accents and languages
- Adjustable speech rate (0.5x to 2x speed)
- Customizable pitch and volume
- Pause and resume functionality
- Works entirely in your browser - no data sent to servers
Use Cases:
- Accessibility - helping visually impaired users
- Proofreading - hearing your text read aloud
- Language learning - listening to pronunciation
- Multitasking - consuming content while doing other tasks
- Content creation - generating voiceovers for videos
Note: Available voices depend on your browser and operating system. Chrome and Edge typically offer the most voices. All processing happens locally in your browser.

The Web Speech API is a browser-native feature that allows web pages to convert text to speech and speech to text without any server involvement. The SpeechSynthesis interface provides the TTS capabilities used by this tool. Because voices are provided by the operating system and browser, the same text may sound different across devices. Chrome on desktop typically provides the best experience with the highest number of high-quality voices. All synthesis happens locally — your text is never sent to an external server.
