Text to Speech

Text to speech has gone from robotic and monotone to genuinely useful in the last few years. Every modern browser ships with the Web Speech API, which gives you access to the same voices your operating system uses for accessibility — including the high-quality neural voices Apple, Google, and Microsoft have shipped. This generator surfaces that system directly so you can pick a voice, tune rate and pitch, and hear your text spoken aloud with one click.

The tool lists every voice available on your device, grouped by language. Install a new voice in your OS settings and it appears here too. That means high-quality English voices like Samantha (macOS) or Eva (Windows) are available alongside dozens of other languages — Spanish, French, Mandarin, Japanese, Arabic, and many more — without any cloud service, API key, or upload. Pick a voice, paste text, click play. You can adjust speaking rate (0.1x to 10x), pitch, and volume before or during playback.

For workflow integration, the tool lets you export the audio as a file. Recording uses the MediaRecorder API to capture the speech output and produce a downloadable MP3 or WebM audio file — perfect for adding voice narration to video tutorials, building accessible web apps, prototyping audiobook workflows, or giving your eyes a rest while someone reads you long articles. All of this runs locally in your browser with no rate limits, no sign-up, and no text ever leaving your device.

The Web Speech API's SpeechSynthesis interface provides text-to-speech functionality in browsers. It exposes voices from the operating system and any installed speech engines. You create a SpeechSynthesisUtterance with text, set properties like voice, rate (0.1-10), pitch (0-2), and volume (0-1), then call speechSynthesis.speak().

Voice availability differs by platform:
- macOS and iOS: ships dozens of high-quality Apple voices; Siri voices can be downloaded
- Windows: ships standard Microsoft voices; Edge Read Aloud uses Azure Cognitive Services neural voices online
- Android: uses Google TTS engine with multiple languages
- Chromebook and ChromeOS: Google TTS voices
- Linux: uses eSpeak or installed voice packages

Neural voices (Samantha on macOS, Eva on Windows 10+) produce markedly more natural speech than older formant-synthesis voices. When available, they appear with a "network" or "high quality" label. Some platforms require downloading enhanced voices from system preferences — this tool surfaces whatever your system has installed.

For recording output, the tool uses MediaRecorder to capture audio from a silent audio element piped through SpeechSynthesis. This approach works in Chrome and Firefox but has inconsistent support in Safari. Exported files are WebM or MP3 depending on browser support, suitable for video editors, podcasts, and audio post-production. Rate and pitch adjustments happen at synthesis time, so they're baked into the recording. Language detection from the input text can auto-select a matching voice where ambiguity is low (common when the text is clearly in one language).

Cloud TTS services like Amazon Polly and Google WaveNet produce very natural voices but cost money, need API keys, and send your text to their servers. Desktop apps like Balabolka work offline but require installation. This browser-based tool uses the voices already on your machine, adds rate/pitch controls, language grouping, and recording support, all with zero setup. Perfect for quick narration, accessibility checks, and any TTS need where your OS voices are good enough (which for most modern devices is very good).
