In this study, 7-to-10- year-old children interacted with a conversational interface in which animated characters used text-to-speech output (TTS) to answer questions about marine biology. Analysis of children’s speech to different animated characters revealed a 29% average change in energy when they spoke to an extroverted loud software partner (E), compared with an introverted soft-spoken one (I). The majority, or 77% of children, adapted their amplitude toward their partner’s TTS voice.
