Abstract: A non-transitory computer-readable storage medium storing a program that causes a computer to execute a process, the process includes identifying, for voice data acquired by a microphone provided in an information processing apparatus, a measurement value of a motion sensor or a geomagnetic sensor of the information processing apparatus at a timing when input of the voice data is accepted; and determining switching of a speaker corresponding to the voice data based on the identified measurement value of the motion sensor or the geomagnetic sensor.

Abstract: A program causes a computer to execute a process for determining points at which the trend of conversation changed. The process includes: obtaining conversation data indicating the content that users spoke in a specified period of time; and determining a point at which the trend of conversation changed in the specified period, based on at least one of the following information items: information on the number of uttered words or characters, information on the number of speakers, and information on the frequency of utterances of positive words or negative words, determined for each unit time based on the obtained conversation data.
