Abstract: We implemented a humanoid robot, ASKA, in our university reception desk for the computerized university guidance. ASKA can recognize a user's question utterance, and answer the user's question by its text-to-speech voice, hand gesture and head movement. This paper describes the speech related parts of ASKA. ASKA can deal with a wide task domain of 20k large vocabulary using a word trigram model and an elaborated speaker-independent acoustic model. ASKA can also make a response with keyword and key-phrase detection in the N-best speech recognition results. The word recognition rate for the reception task is 90.9%, and the rate for the out-of-domain task is 78.9%. The correct response rate for the reception task is 61.7%. Users can enjoy their question-answering with ASKA.
