At what age is speech typically 75% understandable?

At the age of 3 years, children's speech typically reaches a level of 75% understandability. By this age, many children are able to combine words into simple sentences and articulate their thoughts more clearly, making their speech easier for caregivers and others to comprehend. They have usually acquired a significant vocabulary, which contributes to their ability to express themselves in a way that others can understand.

As they approach the age of 3, children are also developing their social skills, which can encourage them to use speech more frequently in interactions with peers and adults. Their articulation improves, and they begin to experiment with more complex sentence structures. This milestone is essential for their overall communication development and serves as a foundation for future language skills.
