I cut this phrase out of a TV series and uploaded to Youtube: https://youtu.be/vfj-fl1wq74
The phrase "I need your help" phonetically looks like [aɪ nidʒyər hɛlp]. I listened to the video over and over again and I hear some stress on "help", but I don't hear any stress on "need" and "your". I know we can stress different words to change the meaning for example:
I need your help - I need your help. I need help, not my brother, not my sister, and not my neighbor.
I need YOUR help - I need YOUR help. I need your help, not your neighbor's help.
However, I'm interested in the context above (the attached video). In the attached video I can't hear any stress other than the word "help", and I think it is the most common way we use the phrase. I would like to have your feedback. I'm not a native speaker and can't distinguish very well.
