The problem with you copying my invention is that you didn't share my research costs, so you could easily beat me on price. But as they are software solutions, I can bring them to market myself without much difficulty. I can hire or partner with the best UX designers and marketing people and I'm protected by copyright.
I wouldn't want to stop you from working out similar ideas and compete with me, nor would I want to become a law firm spending my time in court with people who had similar ideas. Patents are a danger and I don't need their protection because software ideas are either trivial and shouldn't be protected or they are complex and don't need protection beyond copyright and contract law.
I think the issue is that your patent wouldn't cover your algorithm, it would cover "service which translates audio into text."
