Find the missing background sounds in the training set
Question: A voice-assistant team trained on recordings from quiet rooms then evaluated on clips collected in a busy train station. Which two background sounds were present in the evaluation clips but missing from the training data, contributing to poor recognition?
Sample answer: Train rumble and public announcements were missing from the training data but present in the evaluation set.
Key points:
- Train rumble
- Public announcements
Rubric: The response must mention both train rumble and public announcements as the background sounds absent from the training set.
