How to use Text to Speech
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.
