I have an idea for an app that requires a voice recognition translator. I want to be able to speak in a few select languages and have the app translate it in to English text on screen. I know apps like this already exist but mine has a special edge to it that makes it profitable.
Basically my question is... how do I get the coding for a translator? Is there one that is open source? Are there pre existing ones that I can pay a licensing fee for? What is the best way to get a voice translator without paying to have one built from scratch?
