Convert Text to Speech Online

Text to speech (TTS) technology converts written text into spoken words using advanced speech synthesis. This tool uses the Web Speech API built into modern browsers to provide natural-sounding voice output with full control over voice selection, speaking speed, pitch, and volume. Whether you need to listen to articles, proof-read your writing by ear, learn a new language, or create audio content, this TTS converter provides a fast and free solution.

How Text to Speech Works

The Web Speech API is a browser feature that provides speech synthesis capabilities without requiring server-side processing. When you click play, the browser's speech engine converts your text into audio using the selected voice. The API supports multiple languages and voices, with availability depending on your operating system. Windows, macOS, iOS, and Android each provide different sets of voices. Modern speech synthesis produces remarkably natural-sounding output, making it suitable for accessibility, content consumption, and language learning applications.

Customizing Voice Output

This tool gives you complete control over how your text sounds. The speed control ranges from 0.5x (half speed) to 2x (double speed), perfect for careful listening or fast content consumption. Pitch adjustment lets you make voices deeper or higher, useful for creating different character voices or matching personal preferences. Volume control ensures comfortable listening levels. You can combine these settings to create the perfect listening experience for your needs. All changes take effect immediately when you start or resume playback.

Frequently Asked Questions

What is text to speech (TTS)?
Text to speech (TTS) is a technology that converts written text into spoken words. It uses speech synthesis to generate natural-sounding voice output from text input. TTS is used for accessibility, language learning, content consumption, and assistive technologies for people with visual impairments or reading difficulties.
How does the Web Speech API work?
The Web Speech API is a browser feature that provides speech recognition and speech synthesis capabilities. This tool uses the SpeechSynthesis interface to convert text to speech entirely in your browser. The API uses the operating system's built-in voices, so available voices vary by device and OS. No server processing is required - everything runs locally.
What voices are available?
Available voices depend on your operating system and browser. Windows, macOS, iOS, and Android each provide different sets of voices in multiple languages. Common languages include English (US, UK, Australia), Spanish, French, German, Japanese, Chinese, and many more. This tool automatically detects and lists all voices available on your device.
Can I adjust the speaking speed?
Yes! This tool lets you adjust the speaking speed from 0.5x (half speed) to 2x (double speed). Slower speeds are useful for language learning or careful listening, while faster speeds work well for consuming content quickly. The default speed is 1x (normal).
What is pitch control?
Pitch control adjusts the tone or frequency of the voice. Lower pitch values create a deeper voice, while higher values create a higher-pitched voice. The range is 0.5 to 2, with 1 being the default. Pitch control can make voices sound more natural or create different character voices.
Does this tool work offline?
Yes! The text to speech conversion happens entirely in your browser using the Web Speech API. No internet connection is needed after the page loads. Your text is never sent to any server - everything is processed locally on your device.
Can I pause and resume playback?
Yes! This tool provides play, pause, resume, and stop controls. You can pause the speech at any time and resume from where you left off. The stop button ends playback and resets to the beginning. Current word highlighting helps you follow along.
What is word highlighting?
Word highlighting shows which word is currently being spoken by highlighting it in the text. This feature helps with reading comprehension, language learning, and following along with longer texts. The highlighting updates in real-time as the speech progresses.
