From Messy Speech to Perfect Text
Human language is messy — full of filler words, false starts, and repetitions. Watch Hello8 clean it up automatically.
So, um, when we started the— the project, we didn't really, you know, we didn't really understand the full scope of, of what we were getting into? [laughs]

Mm-hmm. And the— and the funding was, was a whole other story. We had to— we had to go back to the, uh, to the board and basically say, “Look, we need— we need more time and more resources.” [pause] Which, you know, was not an easy conversation.
