How to use the extension
Add VoiceVocab to Chrome. The setup takes one click and doesn't ask for an account to try the demo.
Click the VoiceVocab icon on any tab with audio — the demo above, a YouTube clip, a podcast, your call.
Hit record. VoiceVocab grabs the tab audio, processes it, and shows plain-English explanations for technical terms — right where you need them.
