Abstract: This paper is a study on the development of a translation telephone system that enables two individuals speaking different languages to communicate through phone call. The system will be developed using the MQTT protocol - a push service technology - and voice, translation related web services that have been experiencing rapid improvement along with the development in the artificial intelligence technology. The core technologies applied to the system are voice recognition, text translation and speech synthesis. In order to guarantee that the system runs real-time, the system is designed to utilise as many threads as possible so that the functions can be operated simultaneously. In order to minimise communication traffic, the system is designed to convert a conversation into text and send out a translated text to the counterpart instead of sending voice data. Also, to ensure the accuracy of the translation, the system is designed to translate all given information in a sentence basis separately. The proposed system has been developed to operate in Android Smartphone. Because sentences do not tend to be too long during a conversation normally, we can know experimentally that the developed translation telephone system appears to run real-time.

Keywords: telephone system; translation; web service; push service; speech recogniser; speech synthesiser; MQTT.
