We usually say thank you and reply to thank you with intonation going down at the end. When somebody says ‘Thank you' for doing something, we sometimes reply, ‘It's a pleasure', or ‘My pleasure.’ Some other responses to thanks are: ‘You're welcome', ‘That’s all right,’ 'That’s OK.’

Practise ways of saying thank you and responses to thanks with intonation going down on the last strong stress. First listen and repeat the possible responses.
It's a pleasure. My pleasure. You’re welcome.
That’s all right. That's OK.
