Speech recognition is an integral part of the multimodal dialogue system. It transforms the acoustic input signal into an orthographic transcription representing the utterance of the speaker. This contribution discusses how to enhance and customize the speech recognizer for the SmartKom applications. Significant improvements were achieved by adapting the speech recognizer to the environment, to the speaker, and to the task. Speech recognition confidence measures were investigated to reject unreliable user input and to detect user input containing unknown words, i.e., words that are not contained in the vocabulary of the speech recognizer. Finally, we present new ideas for future work.}, timestamp = {2008.01.20}, file = {Preprint:2006/BertonKaltenmeierEtAl06p85.pdf:PDF}, isbn = {3-540-23732-1}, owner = {flint}, keywords = {ai paper recognition smartkom speech v0805 } }
