Server apparatus, voice operation system, voice operation method, and recording medium

A voice operation system for controlling operation of an image forming apparatus based on voice operation input via a speaker, the voice operation system comprising circuitry configured to:

• acquire, from the image forming apparatus, a language type of a display language used for display at the image forming apparatus;
• store, in a memory, an apparatus identifier identifying the image forming apparatus in association with the language type of the display language of the image forming apparatus;
• acquire, from the speaker, voice operation including an instruction to change the display language;
• identify a language type of a targeted language based on the voice operation;
• determine whether the language type of the display language matches the language type of the targeted language stored in association with the apparatus identifier of the image forming apparatus as a subject to be changed;
• instruct the image forming apparatus to change from the language type of the display language to the language type of the targeted language, in response to a determination that the language type of the display language does not match the language type of the targeted language;
• and
• omit instructing the image forming apparatus to change the language type of the display language of the image forming apparatus, in response to a determination that the language type of the display language matches the language type of the targeted language.

A voice operation method executable on a server apparatus controlling operation of an image forming apparatus based on voice operation input via a speaker, the voice operation method comprising:

• acquiring, from the image forming apparatus, information on a language type of a display language used for display at the image forming apparatus;
• storing an apparatus identifier identifying the image forming apparatus in association with the language type of the display language;
• acquiring, from the speaker, voice operation including an instruction to change the display language;
• identifying a language type of a targeted language based on the voice operation;
• determining whether the language type of the display language matches the language type of the targeted language stored in association with the apparatus identifier of the image forming apparatus as a subject to be changed;
• instructing the image forming apparatus to change from the language type of the display language to the language type of the targeted language, in response to a determination that the language type of the display language does not match the language type of the targeted language;
• and
• omitting instructing the image forming apparatus to change the language type of the display language of the image forming apparatus, in response to a determination that the language type of the display language matches the language type of the targeted language.
