Case context: A speech-system team needs more data that sounds as if it came from inside a car. It already has many quiet-room speech recordings and can obtain many car or road noise clips.

Question: What should the team do with these resources, and what result should it expect?

Sample answer: The team should add the car or road noise clips to the quiet-room speech recordings. The resulting audio should sound as if the speakers were talking in noisy cars, providing an easier alternative to collecting a large amount of speech while driving around.

Key points:

• Use the existing quiet-room speech recordings.
• Use the available car or road noise clips.
• Add the noise audio to the speech audio.
• Expect speech that sounds as if recorded in a noisy car.
• The method can avoid extensive data collection while driving.

Rubric: The response should recommend combining the two supplied audio sources, correctly identify which sound is added to which recording, state the expected noisy-car result, and connect the choice to the stated collection alternative.
