Abstract(in English) | The development of the speech-oriented guidance system Takemaru is simulated using the data collected during the first two-years of regular operation. The relationship between the period of data collection, the number of speech inputs, number of words, language model perplexity, OOV rate, speech recognition performance and response accuracy is investigated. Based on this analysis, the relative importance of developing each system component can be assessed. Most important are efforts regarding the Q&A database followed by the acoustic and the language model. Moreover, a maximum in system performance seems to be reached after one year of data collection and overall improvement has the tendency to stagnate even if more data becomes available. Apart from that, the portability of the Takemaru system regarding a different environment, the Kitachan system installed at a local subway station, is investigated. Assuming a more realistic setting, only the data collected during twenty days is employed for system development. While the Takemaru ASR component shows a high portability, more efforts regarding the question and answer database have to be carried out in the future. |
