A greeting and a sound change
你好 is written nǐ hǎo. Before another third tone, the first third tone is normally pronounced with a rising second-tone contour: roughly ní hǎo. This is third-tone sandhi. Keep the dictionary spelling nǐ hǎo while learning how the phrase sounds.
Ask and answer a name
我叫… means My name is…: put your name after 叫. 你叫什么名字？ asks What is your name? 什么 replaces the unknown information; you do not add 吗 to this question. Practise greeting, question and answer as separate short turns.
