1. A conversation analyzing device comprising: a conversation data acquiring unit, implemented via at least one processor, configured to acquire conversation data indicating speech of each of a plurality of speakers in a conversation; a conversation state analyzing unit, implemented via the at least one processor, configured to analyze an amount of speech of each of the plurality of speakers in the conversation and a degree of influence of the speech of each of the plurality of speakers on the conversation based on the conversation data; and a role determining unit, implemented via the at least one processor, configured to determine a role of each of the plurality of speakers in the conversation based on the amount of speech and the degree of influence of the speaker, wherein the degree of influence includes a facilitator level index value, the facilitator level index value being indicative of a degree to which one of the speakers facilitates speech of other speakers in the conversation and includes as a component thereof a speech amount correction level, the speech amount correction level being indicative of a degree to which a deviation in the amount of speech among the plurality of speakers is lessened and a degree to which the amount of speech of other speakers is corrected by the one speaker from a natural state to an ideal state, wherein the natural state is an average amount of speech of the other speakers in a previous conversation and the ideal state is a state in which amounts of speech of each of the plurality of speakers are equal to each other in a current conversation, the role determining unit determines whether the role of the one speaker is a facilitator based on the facilitator level index value; and a display unit to output image data including data representing the determination of whether the role of the speaker is a facilitator.
