Especially with very precise language. I've heard of people using speech to text to use it which opens up all sorts of accessibility windows.
I’ve experimented with several dictation apps, including super whisper, etc., and I’ve settled on Wispr Flow. I’m very picky about having good keyboard shortcuts for hands-free dictation mode (meaning having a good keyboard shortcut to toggle recording on and off), and of course, accuracy and speed. Wispr Flow seems to fit all my needs for now but I’d love to switch to a local-only app and ditch the $15/mo sub :)
So whats the benefit? Well for Claude Code this wrapper effectively bridges those TTS/ASR systems and CC so the voice interface is now there (CC doesn't have one). It doesn't just rely on MCP either (although it does start an MCP server for configuring via prompting) but instead directly injects the ASR and directly reads out CC's output when on.
It is free and open source so folks can inspect it and check it's not doing anything nefarious, so that others can contribute if they should choose. And the license is what it is as that seems to be the advice on this forum if you want to make sure a company can't just make a paid service out of your work.
