Multi-Access Network-Based TTS Architectures

There are many areas were text-to-speech (TTS) synthesis could enhance the end-user experience or even change the behavior of using existing network services starting from simple notification applications to complex presence enabled instant messaging convergent services. For this to happen we may need to bring TTS service in the multi-access area of Internet Multimedia Subsystem (IMS) networks and implement network-based TTS architectures. This paper proposes a pre-IMS network architecture leveraging a Romanian TTS system and a reference framework for developing future convergent network services around TTS technology. Key-words: Multi-access, network-based speech processing, IMS network, MRCP, presence, instant messaging.
