Listening Test

Tips：

1. MOS evaluation for NN-based speech super-resolution.

2. Listen to all utterances in the Table and score them subjectively. In specific, the clean audio files serve as the reference, which are the ceiling perceived quality comparing to those processed by other methods, such as NB.

3. MOS ranges from 1 to 5. The higher score, the better performance.
