Custom TTS Reader: OpenAI-Compatible Text-to-Speech

Custom TTS Reader is a Firefox extension designed for users who want to integrate their own OpenAI-compatible speech endpoint into their browsing experience. This subscription-based tool provides a straightforward approach to converting text into speech by simply highlighting the desired text and selecting 'Read Selected Text' from the context menu. Users can customize the API URL, API key, voice, and speed directly from the extension's toolbar icon, making it highly adaptable to individual preferences.

The extension supports two modes of operation: streaming and download. Streaming mode allows real-time audio generation, which is ideal for immediate playback, while download mode provides the option to save the audio as an MP3 file. With privacy and accessibility contingent on the user's chosen endpoint, Custom TTS Reader stands out as a flexible solution for language learning and reference, appealing to users needing tailored text-to-speech functionalities.
