Do you mean being able to generate an answer based on what the student says? If so, unfortunately no. This would require AI, and right now Cospaces does not support that. Though it would be a good idea!
You can try to put the questions in a choice panel and depending on the selected question, to play a pre-recorded answer and make the character say the answer as well. You can record or upload audio files in Cospaces and use them to teach pronunciation.
This could be an alternative to your idea, because as @gorillamonkeybanana mentioned, you can not detect audio input in Cospaces.
