In Week 3 of the course multiple videos starting from video number 2 Neural Network Representation, have audio issues. It seems that the audio stitching for these videos has not been done properly resulting in broken sentences and some skips and jumps.
Here is the link for one of the videos: https://www.coursera.org/learn/neural-networks-deep-learning/lecture/GyW9e/neural-network-representation
Kindly look into it as it is an intermediate level course and some concepts might be confusing to those venturing into this specialization or course after taking some basic courses.
Thanks
