It's an interesting idea, but this seems more like something that could be a neat tech demonstration rather than a product that people would want to use.<p>First, speech recognition is very difficult. Fortunately you have a limited number of key words you have to support. Unfortunately, there's an almost infinite number of symbol names available, many of which can't be pronounced in a definite way. Variables created through speech recognition are going to be pronounceable, but what if you're working on a project with someone else who's not using speech recognition? What if you're working on existing code and don't want to refactor all the variable names? It seems to me that this could be even more difficult than natural language speech recognition.<p>Second, what problem does this solve? You mentioned RSI sufferers, which is certainly a problem, but how large is the market of Python programmers suffering from RSI? I'm guessing not that large. The software would have to be extremely accurate in order for me to not get quickly frustrated. On top of that, it would have to offer some benefit over typing, and that's not something I see in your pitch.<p>Third, I'm not so sure about your business model. I think in order for people to want to pay to download their personal acoustic model, the default model would already have to work really well. If it didn't, programmers would probably find themselves thinking "If the default model works so poorly, will the custom model really be that much better?" However, if it's too good, then there's no incentive to get the custom model. You're creating a balancing act that you'll have to perform in order for anyone to want to give you money.<p>A more interesting goal would be to supplement the keyboard and mouse setup rather than replace it. Think of ways that any programmer might become more productive through using voice in addition to hands. This would probably be much simpler, which allows you to release more quickly. I think it would also increase your potential user base, and eventually you could expand it to do everything if need be.
