Multi-Lingual Speaker-Independent Voice User Interface For Mobile Devices

This paper presents a multi-lingual speaker-independent voice user interface (UI) that has been implemented for Nokia S60 mobile phones. The paper concentrates on discussing the specific approach used for achieving a multi-lingual and configurable speech recognition and speech synthesis system. The main applications are speaker-independent name dialing and voice commands. The novelty of the applications is that the user does not need to train the voice dialing system but the application reads the user´s phonebook and generates the required voice tags automatically. The speaker-independent voice dialing has already been introduced in regions where the language diversity is not so great. The system presented in this paper is the first of its kind to support both speech recognition and speech synthesis in more than 40 languages in embedded devices with strict memory and performance requirements
