BetterTTS
BetterTTS is a premium AI text-to-speech Chrome extension that reads web pages and PDFs aloud using advanced generative AI voices. It leverages the Kokoro TTS engine and Misaki G2P pronunciation system to deliver human-like speech across multiple languages, including English, Spanish, French, Chinese, and Japanese (on Windows/Linux). The extension offers a seamless reading experience with word-by-word highlighting, auto-scroll, and automatic next-page navigation for multi-page articles. A companion desktop app (available for macOS, Windows, and Linux) provides enhanced performance with multi-threaded C++ processing, stutter-free playback, and zero CPU overhead on the browser. All speech synthesis runs locally on the user's device, ensuring complete privacy and offline availability. The AI models are trained exclusively on public domain audio, making the tool ethically sourced. BetterTTS includes a custom PDF reader that supports page range selection, skipping, and thumbnail navigation, making it ideal for long documents and textbooks.
