[tex]\bf Explanation[/tex]
Intonation is the rise and fall of your voice when you speak. For example, your voice raises its pitch when you ask a question, whilst when you're making a regular statement, such as "my favourite colour is green, it uses a falling intonation at the end. Audiences are able to identify your mood when you use intonation in a speech. Whether you're angry, happy, excited, etc.
