Abstract
The latest Hungarian text-to-speech (TTS) system developed for telephone-based applications is described. The main features are intelligible human-like voice; robust software designed for continuous running; fully automatic conversion of declarative (short and very long) sentences and questions; and real time parallel operation, running on minimum 30 channels. The concept of prosody generation and sound duration processing is introduced. Also, the development environment of Profivox is presented. The market-leader Hungarian mobile service provider applies the TTS system in an automatic e-mail reading application.
