Why do dogs tilt their heads?
The Real Answer
No single universal reason explains why dogs tilt their heads. In experiments, dogs that had learned object names tilted more often while hearing meaningful familiar words, suggesting head tilting can accompany focused processing of relevant sounds. Dogs also tilt in many other situations, so the behavior is better treated as a context-dependent attention or sensory response than as proof of confusion, cuteness, or manipulation.
Your dog tilts its head while you talk and you immediately promote the moment into proof that it understands your entire emotional life. Then you repeat the sentence in a higher voice because you have decided pitch is the missing translation layer.

A head tilt looks so deliberately inquisitive that people naturally read a whole thought process into it. Research supports a link with attentive processing in some dogs, but the gesture is not a universal translation for 'I am confused.'
