What Is a Text to Speech Preview Tool?
A text to speech (TTS) preview tool converts written text into spoken audio using the browser’s built-in Web Speech API. It lets you hear how text sounds before using it in presentations, videos, or accessibility applications. No server-side processing is needed since everything runs locally in your browser.
How to Use This Text to Speech Tool
- Type or paste text into the input area.
- Select a voice from the dropdown. Available voices depend on your operating system and browser.
- Adjust speed and pitch using the sliders.
- Click Play to hear the text. Use Pause and Stop to control playback.
Key Concepts
The Web Speech API provides speech synthesis capabilities built into modern browsers. Voices are provided by the operating system, so Windows, macOS, and Linux each offer different voice options. Rate controls how fast the speech plays (0.5x to 2x), while pitch adjusts the tonal frequency. Most browsers support multiple languages and accents.
Frequently Asked Questions
Why do I see different voices on different devices?
Voices are provided by your operating system, not the browser. macOS includes voices like Samantha and Alex, Windows has David and Zira, and Chrome on Android uses Google TTS voices. Installing additional language packs adds more options.
Does this tool send my text to a server?
No. The Web Speech API runs entirely in your browser using local speech synthesis engines. Your text never leaves your device, making it safe for confidential or sensitive content.
