Can I get away with raw voice transcription?

I'm trying a slightly weird experiment with voice transcription.

I started using Fluid Voice, an open source Wispr Flow alternative. One of its best features is a local model that cleans up the raw transcript before inserting it. It fixes punctuation, removes some of the spoken mess, and can tell that something I said was a question even when speech-to-text can't.

Then I added a feature I've always wanted: automatically submit the transcript without making me press enter.

It worked, except the debug version I built from source couldn't use their local cleanup model. That model is apparently only available in their version of the app.

I could use a remote model like OpenAI, but that adds about three seconds of latency to every voice input. It really sucks compared to the local model.

So now I've accidentally forced myself to try talking directly to agents with raw speech-to-text and no cleanup step at all.

The upside is that it's insanely fast. The transcript appears and submits immediately. Combined with auto-submit, I can do quite a bit now with just my left hand.

The question is how much the cleanup actually matters.

When I'm talking to Codex, the difference between a statement and a question can completely change what it does next. Raw speech-to-text doesn't always know I asked a question. The cleanup isn't just making my words prettier. It's helping communicate intent.

This post is the first test. I brain dumped the raw transcript into Codex and had it turn the mess into what you're reading now.

I'm curious whether I can get away with dropping cleanup entirely, or whether punctuation turns out to be a surprisingly important part of the voice interface.
