Document Type and Number:
WIPO Patent Application WO/2021/260846
Kind Code:
A1
Abstract:
This voice generation device (1) has an acquisition unit (21), a determination unit (22), a selection unit (23), and a generation unit (24). The acquisition unit acquires an alertness degree representing a user's degree of alertness from sleep to excitement. The determination unit determines, on the basis of the alertness degree, whether the user is in a state of alertness. When the user is not in a state of alertness, the selection unit selects a voice prompting the user to be alert from among a plurality of voice candidates, this selection being made on the basis of a familiarity degree representing the degree to which the user is familiar with each of the plurality of voice candidates and a concentration degree representing the user's current degree of concentration. On the basis of the selected voice, the generation unit generates a calling-out voice to be presented to the user.
