How to use Text to Speech

Text to speech converts written text into spoken audio using your browser's built-in speech synthesis engine. No audio files are uploaded or generated on a server — everything runs locally in your browser using the Web Speech API, ensuring complete privacy. How to use: 1. Paste or type your text into the input field. 2. Select a voice from the dropdown. Available voices depend on your operating system and browser — Windows, macOS, iOS, and Android each include different voice libraries. 3. Adjust speech rate (0.5 to 2.0x speed) and pitch (0.5 to 2.0). 4. Click Speak. The text is read aloud. Use Pause, Resume, and Stop controls. 5. Long text is read continuously — no limit on character count. Voice selection: Most systems include multiple voices for common languages. On Windows, Microsoft voices like David, Zira, and Mark are available. On macOS, Siri voices and additional voices can be enabled in System Settings > Accessibility > Spoken Content. On Android, Google Text-to-Speech provides voices. Install additional language packs in your OS settings to add more voice options. Speed control: 1.0 is normal speaking pace (~150 words per minute). 0.5 is slow for learning or transcription. 1.5-2.0 is fast for review or speed listening. Useful for: Proofreading — hearing text read aloud catches errors the eye skips. Language learning — listen to pronunciation of words and phrases. Accessibility — reading assistance for dyslexia or visual impairment. Multitasking — listen to articles or documents while doing other tasks. Pronunciation checking — verify how names, foreign words, or technical terms sound.

Frequently Asked Questions

Why are different voices available on different devices?

The Text to Speech tool uses the Web Speech API, which relies on voices installed in the operating system. Each OS comes with different built-in voices. Windows includes Microsoft voices; macOS includes Apple voices (Siri and others); Android uses Google TTS voices. More voices can be added by installing language packs in your system settings.

Does the text get sent to any server?

No. All speech synthesis happens locally in your browser using the Web Speech API. No text is sent to any external server for processing. This makes it completely private — suitable for reading sensitive documents, personal notes, or confidential content without any data leaving your device.

Is there a character or word limit?

No hard limit is imposed by this tool. The Web Speech API handles long text by reading it as a continuous stream. Very long texts (10,000+ words) work fine — the speech engine reads until stopped. Use the Pause and Resume controls to take breaks without restarting from the beginning.

Can I use Text to Speech for language learning?

Yes. Select a native speaker voice for the target language and listen to correct pronunciation of words, phrases, or full sentences. Slow down the rate to 0.6-0.7 for clearer phoneme separation. Many OS voice libraries include regional accents for languages like English (UK vs US vs Australian), Spanish (Spain vs Latin American), and Portuguese (Brazil vs European).

Why does the voice sound robotic on some systems?

Voice quality depends entirely on the voices installed in your operating system. Older OS voices use formant synthesis, which sounds robotic. Newer neural text-to-speech voices (Microsoft's neural voices on Windows 11, Apple's enhanced Siri voices on macOS/iOS) sound significantly more natural. Enable enhanced quality voices in your OS accessibility or speech settings for the best results.
