Star Trek: Voyager works well for learners who already understand English comfortably and want more challenging listening practice. The vocabulary is not overly technical, though it includes enough variety to make the practice meaningful. At an intermediate level, the main story should be easy enough to follow. The pace feels realistic without being constantly overwhelming, with an average speaking rate of around 80 words per minute. For learners around B2/C1, this can be a practical choice for building confidence with more complex narratives.
