To change your voice in English, you can practice using different pitch, volume, and tone. Here's how:

1. Pitch: The higher or lower your voice is, the more it changes. To raise your pitch, speak with a higher tone, like when you're surprised or excited. To lower your pitch, speak with a deeper tone, like when you're calm or serious.

3. Tone: The way you inflect your voice at the end of a sentence can also change your voice. For example, a questioning tone usually goes up at the end, while a declarative tone stays steady.

Practice these techniques by reading aloud or recording yourself and listening back. Over time, you'll become more comfortable with changing your voice in English.
