Speech generation model 529 is utterance data of users (eg, all users or individual users) associated with a first intention (eg, AC off, set temperature) and a second intention (eg, TV turn on, weather, set temperature). You can generate a predictive utterance (eg air conditioner 24 degrees, air conditioner off, TV on, today's weather) based on (eg air conditioner 24 degrees, air conditioner 24 degrees). The predictive utterance generation model 526 may generate a predictive wake-up word (eg, air conditioner 24 degrees, turn off the air conditioner, turn on the TV, today's weather) by setting the predictive utterance as the predictive wake-up word.
