Integrated Recognition and Interpretation of Speech for a Construction Task Domain

The development of speech processing front-ends for the controlling of complex systems has received more and more interest during the last years. Usually this task is divided in two subtasks. The speech recogniser records the utterance and puts out a corresponding text, and the speech understanding module tries to extract an internal representation of the meaning of the utterance. As shown in Figure 1 the recogniser uses an acoustic model as well as a statistical language model, which are both generated from a corpus. The speech understanding uses linguistic and domain specific knowledge designed by experts.
