1. To produce sounds with the voice: This is the most common meaning. It refers to the act of speaking, singing, or making any other sound using your vocal cords. Examples:
* "The baby began to vocalize, making soft cooing sounds."
* "The singer vocalized beautifully, hitting every note perfectly."
* "The animal vocalized with a loud roar."
2. To express thoughts or feelings in words: This meaning is less common, but it refers to the act of putting your thoughts and feelings into words, either spoken or written. Examples:
* "It's important to vocalize your concerns to your manager."
* "The artist used his art to vocalize his social commentary."
* "She vocalized her disappointment with the decision."
In both cases, the word "vocalize" implies the use of voice to communicate something, whether it's a sound or an idea.
