In this paper we present an embedded unified speech recognizer and synthesizer using identical, speaker independent Hidden- Markov-Models. The system was prototypically realized on a signal processor extended by a field programmable gate array. In a first section we will give a brief overview of the system. The main part of the paper deals with a specially designed unit based HMM synthesis algorithm. In a last section we state the results of an informal listening evaluation of the speech synthesizer.
