About Sangar Studio ReadFlow
From the official readme · v1.3.0Description
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.
Key Features
- Accurate Reading Time Indicator: Computes reading times based on custom Words Per Minute (WPM) settings.
- Premium Custom HTML5 Player: Ditch the default browser audio bar. Features stylized play/pause buttons, loading spinners, sound-wave animations, and draggable seek sliders.
- OpenAI TTS Integration: Access six natural voices (Alloy, Echo, Fable, Onyx, Nova, Shimmer) with standard
tts-1or high-definitiontts-1-hdqualities. - Unlimited Text Length Chunking: Sentence-intelligent text-splitting bypasses API size caps for infinite post narration.
- Smart Local Caching: Saves generated MP3s locally. Zero repetitive API billing overhead for repeat readers.
- Auto Pre-Generation: Optional setting pre-renders post narration in the background as soon as you hit “Publish”.
- Sleek Administration Panel: Manage credentials, customize accent colors, adjust reading formulas, check cache sizes, test voices with live playback, and flush files with one click.
- Zero-Config Web Speech Fallback: Universal native voice narration fallback if AI models are disabled or run out of quota.
- Adjustable Playback Velocity: Speed options (
0.8x,1.0x,1.2x,1.5x,2.0x) for listeners on the go. - Direct MP3 Download Link: Give readers the option to take post narrations with them.
Privacy & Third-Party Service Disclosure

Frequently asked questions
Does this plugin work without an OpenAI API Key?
Yes! Without an API Key, Sangar Studio ReadFlow automatically switches to the Web Speech API fallback, synthesizing text-to-speech using the reader’s native browser voice.
How does local MP3 caching work?
When an article is listened to for the first time (or pre-generated upon publishing), the audio file is stored in wp-content/uploads/sangar-studio-readflow/. All future visitors listen directly to this local file with 0 ms generation latency and zero API cost.
How is cache invalidated when I edit a post?
The plugin listens to post updates. Saving, editing, or trashing a post automatically deletes its corresponding cached MP3 so that the fresh content is compiled on the next listener’s play click.
Does the text chunking support very long articles?
Yes! Sangar Studio ReadFlow breaks articles into smart, semantic chunks of approximately 3,500 characters, avoiding breaking mid-word or mid-sentence. It submits each chunk sequentially and compiles the resulting binaries into a unified audio stream, bypassing OpenAI’s 4,096 character limit easily.
How can I place the widget or Author Box manually?
Select “Insertar manualmente” in the settings, and insert the shortcode [sangar-studio-readflow] for the audio player, and [ssrf_author] (or [ssrf_author_box]) for the Author Box anywhere in your post text or theme files: (The legacy shortcode [readio] is also fully supported for backward compatibility).
Can I customize the Author Box social icons and avatar shape?
Yes! From Settings > ReadFlow 🎙️, you can choose circle, rounded, or hexagon avatar styles with a hover glow effect, and toggle between SVG icon buttons or branded text links for LinkedIn, X, Instagram, GitHub, and Website.
