Source-filter model of speech production

Okay kiddo, so when we talk, the sounds we make come from two main things: our voice and our mouth.

Our voice makes a big sound that starts in our throat and comes out of our mouth as a vibrating sound wave.

Our mouth shapes that sound wave into the different sounds we want to make using our tongue, lips, and other parts of our mouth.

So, the source-filter model of speech production is how scientists try to understand these two parts of talking.

They think of our voice as the "source" because it starts the sound wave. And they think of our mouth as the "filter" because it changes the sound wave into different speech sounds.

Scientists use this model to study things like how different languages make different sounds and how people with speech disorders might produce sounds differently.

So basically, when we talk, we use both our voice and our mouth to make the sounds we want to make. And the source-filter model helps scientists understand how this all works together.
