I want to integrate language converter in VoIP based iOS client app which will translate real time incoming audio stream to other selected languages based on user choice, I am using PjSip open source library to support VoIP Calls. For language translation I want to use speech to text and text to speech open source library. Now I am facing following issues : 1. How to catch the incoming audio stream in PJSip ? 2. How to send the converted audio stream which user can listen like in normal audio call ? Please help.Thanks. -------------- next part -------------- An HTML attachment was scrubbed...
