Access-independent Cloud-based Real-Time Translation Service for Voice Calls in Mobile Networks

Nokia offers a speech translation solution for mobile network operators. Operators can provide real-time machine translation of speech, as a useful extension to their currently available voice service. The concept provides a beneficial difference against Over-the-Top (OTT) service providers. The successfully implemented solution presented in this paper works with any device, that is capable of voice calls (even with simple handsets, like the recently launched Nokia 3310). In the service, the Operator's MSS (Mobile Switching Center Server) or IMS (IP Multimedia Subsystem) core is involved. The core network is connected to the Microsoft Azure Data Center that provides the speech translation through a Nokia Translation Application Server, running in a Nokia Data Center.
