Information processing apparatus, information processing method, and information management apparatus

An information management apparatus comprising a processor coupled to a memory storing instructions that, when executed by the processor, configure the processor to:

• identify an identification information that corresponds to a sound-specifying information output from a guidance instruction apparatus by referring to management data in which, for each of multiple guide voices, a sound-specifying information that specifies an array of speech segments forming the guide voice is associated with an identification information of the guide voice;
• and
• generate a modulation signal indicative of the identified identification information.
