Spotlight Reader: Text-to-Speech & Highlighting by lucas

Spotlight Reader reads the article on the current web page aloud and highlights each sentence as it is spoken — directly on the page, Speechify-style. Click any sentence to jump to it.

★ Reading experience
- Sentence-level in-page highlighting with hover preview and click-to-seek.
- Voice favorites, per-language auto-select, adjustable speed.
- Redesigned settings with light/dark mode.

★ Many voices
- Free online: Google Translate.
- Offline: Supertonic and Piper.
- Optional cloud voices with your own API key: Google WaveNet/Neural2/Chirp3-HD, Amazon Polly, Microsoft Azure, OpenAI (and OpenAI-compatible), IBM Watson.

★ Offline & private
- Supertonic neural TTS runs fully on your device (31 languages incl. German, English, Spanish, French, Korean, Portuguese). Install once, then no internet and no account required.
- No telemetry, no unsolicited network requests.

Spotlight Reader is an independent fork of the open-source "Read Aloud" by ken107 (MIT-licensed), focused on offline TTS and in-page highlighting for Firefox.
