9. A speech recognition method in a computer system that carries out speech recognition, the speech recognition method comprising: performing an acquisition process including acquiring a speech command spoken by a user; performing a request process including requesting a speech recognition server that carries out speech recognition of the speech command acquired in the acquisition process; performing a prediction process including predicting a present delay time until a result of the speech recognition requested in the request process is obtained from the speech recognition server; performing a determination process including determining a filler word with a time length in accordance with the present delay time predicted in the prediction process; performing a filler speaking process including outputting the filler word, which is determined in the determination process, as speech information during a waiting time until the result of the speech recognition requested in the request process is obtained from the speech recognition server; when the result of the speech recognition is acquired from the speech recognition server, performing a response process including responding to the user based on the acquired result of the speech recognition; and performing an acquiring process including acquiring time information expressing past delay times when communication has been carried out with the speech recognition server in past, wherein: in the prediction process, the present delay time until the result of the speech recognition is obtained from the speech recognition server is predicted based on the past delay times expressed by the time information acquired in the acquiring process.
