I have started to work on a real-time language translation system for which I wanted to make use of a machine translation API but I do not know which of the many such APIs is good for my project.I was looking for an API that can translate many of the standard languages(should be good at handling informal speech) and is highly optimised so that it can translate a given text as quickly as possible (I will be first converting the speech into text using google's API). Which API should I be Using?
I tried using applications using such APIs but I haven't got the time to checkout all of them. It would be really helpful if you could give the feedback on such APIs you have worked on or familiar with.
