Edited or modified listening materials are most appropriate for Beginner level students. This is because these students are just starting to learn the language and may struggle with understanding native speakers who use complex vocabulary and speak at a fast pace. Modified materials can simplify the language and slow down the speech, making it easier for beginners to understand and learn from.

Bilingual level students, who are already fluent in two languages, may not need modified materials as much. They can likely understand native speakers well and can benefit from unedited materials that provide more of a challenge and help them to become more proficient.

Intermediate and advanced level students can also benefit from unedited materials, as they are at a level where they can understand and learn from native speakers. However, they may still benefit from some modified materials that focus on specific language skills they want to improve.
