Text to Speech uses the Web Speech API's `SpeechSynthesis` interface — the same engine that powers screen readers on macOS, Windows, Android, and iOS — to read any text aloud. Because the voices come from your operating system, quality varies: recent macOS and iOS ship with Apple's high-quality Siri voices, Windows 11 offers Microsoft Natural voices, and Android/Chrome supply Google's WaveNet voices when online. The tool detects every voice installed on your device and lists them by language, letting you switch between accents (British English, Indian English, Australian English) and voice types (male, female, child) with one click. You can adjust rate (0.5×–2×), pitch (0–2), and volume in real time, pause and resume mid-sentence, and export the audio via your browser’s Save-Audio option where supported. Everything happens locally — no text is sent to a cloud TTS provider — which matters when the source is a private email or unpublished script.
Free, fast, and runs entirely in your browser — no signup, no upload to a server.
