What is speech-speed?

Speech Speed is a JavaScript Chrome extension that auto-adjusts video playback speed to normalize the speaker's talking rate—speeding up slow talkers for 2-3.5x playback while easing fast ones to ~1.1x. Toggle it on via popup for any page's largest video element, like YouTube or lectures, and it targets your preferred syllable-per-second rate (default 9). Load unpacked from GitHub or hunt similar tools in the chrome extension store alongside adblockers and video downloaders.

Why is it gaining traction?

It beats manual speed sliders or basic chrome extensions by using browser audio capture for real-time adaptation, with a persistent overlay displaying current speed, natural syl/s rate, energy bars, and speed history logs. Popup sliders let you tweak target rate, min/max speeds, and silence handling, persisting across sessions. Devs grab it for the detailed tuning guide on energy thresholds and filters, standing out in the chrome extensions ecosystem like github copilot plugins or notifications helpers.

Who should use this?

Tutorial grinders watching chrome github issues walkthroughs, bootcamp students powering through variable-pace lectures, or podcasters previewing audio mixes. Suited for desktop Chrome users (works on linux, less so mobile chrome extensions android/ios/ipad), avoiding DRM sites like Netflix.

Verdict

Grab it if dynamic video speedup fits your workflow—strong docs and diagnostics make the 19 stars and 1.0% credibility score forgivable for this raw prototype. Sideloading beats waiting; test thoroughly on speech-heavy content.
