Sangar Studio ReadFlow

Sangar Studio ReadFlow is a premium, high-fidelity WordPress plugin designed to elevate the user reading and auditory experience on your website. It calculates the reading time of your posts based on custom speed parameters and inserts a gorgeous, glassmorphic player widget that lets users listen to posts.

By integrating directly with OpenAI’s state-of-the-art TTS models, Sangar Studio ReadFlow converts your blog content into natural, fluid, human-like voice recordings. It handles OpenAI’s character limitations gracefully by dividing long essays into sentence-aware blocks and stitching the audio binaries together seamlessly.

To protect your budget and increase speed, Sangar Studio ReadFlow features a robust local caching system. It generates the voice file only once per post and caches it directly inside your server’s uploads directory. Every subsequent listener loads the audio instantly in a custom-designed web player.

If no API Key is provided, or if the API suffers a network failure, the plugin automatically falls back to the Web Speech API SpeechSynthesis, providing free, zero-config native voice synthesis directly inside the reader’s browser.
