A control apparatus comprising: a speech acceptance block configured to accept a speech; an execution block configured to execute processing according to a result of recognition of the speech; an output control block configured to execute output control so that information indicative that execution of processing based on speech recognition is disabled is outputted; a control information acceptance block configured to accept control information for controlling enablement/disablement of the execution of processing based on speech recognition from a program being executed; and an execution enable/disable control block configured to control enablement/disablement of the execution of processing according to the result of the recognition of the speech on the basis of the control information accepted by the control information acceptance block , wherein, the execution enable/disable control block executes control to disable the execution of processing according to the result of the recognition of the speech while a voice chat between users is executed by a voice chat sub module , the voice chat sub module configured to execute chat based on a speech between a user of the control apparatus and another user, and if control is executed to enable the execution of processing based on speech recognition, the execution block executes the processing according to the result of the recognition of the speech if the recognition of the speech is successful, and, if control is executed to disable the execution of processing based on speech recognition, the output control block executes control so that information indicative that the execution of processing based on speech recognition is disabled is outputted if the recognition of the speech is successful. a speech acceptance block configured to accept a speech; an execution block configured to execute processing according to a result of recognition of the speech; an output control block configured to execute output control so that information indicative that execution of processing based on speech recognition is disabled is outputted; a control information acceptance block configured to accept control information for controlling enablement/disablement of the execution of processing based on speech recognition from a program being executed; and an execution enable/disable control block configured to control enablement/disablement of the execution of processing according to the result of the recognition of the speech on the basis of the control information accepted by the control information acceptance block , wherein, the execution enable/disable control block executes control to disable the execution of processing according to the result of the recognition of the speech while a voice chat between users is executed by a voice chat sub module , the voice chat sub module configured to execute chat based on a speech between a user of the control apparatus and another user, and if control is executed to enable the execution of processing based on speech recognition, the execution block executes the processing according to the result of the recognition of the speech if the recognition of the speech is successful, and, if control is executed to disable the execution of processing based on speech recognition, the output control block executes control so that information indicative that the execution of processing based on speech recognition is disabled is outputted if the recognition of the speech is successful. <EOS>
