['9. A speech service control apparatus (110) comprising: a speech receiving device (111), receiving speech data; and a processor (113), coupled to the speech receiving device (111), and configured to: recognize a keyword in the speech data to determine a confidence value corresponding to the keyword, wherein the confidence value is a match level of the keyword relative to a wakeup keyword to request for a speech service; determine a number of cumulative failures in response to a determination that the confidence value is inferior to a recognition threshold, wherein the speech service is requested when the confidence value greater than the recognition threshold is determined, and the number of cumulative failures is a cumulative number accumulated when the confidence values of the speech data and at least one previous speech data are inferior to the recognition threshold within a time period; and modify the recognition threshold according to the number of cumulative failures and a calculation relationship of the confidence values of the speech data and the previous speech data.']
