Here are five sound acquisition charts based on the work of different people in the field. Two of them are for Spanish development and three of them are for English development. They all differ slightly based on level of mastery and the natural variation that exists in the population. No single chart is the gold standard. They should be used
The attached document is a list of all developmental norms that you would expect for any child, regardless of home language. apples-to-apples-for-speech-and-language
Spanish and English Artic Norms This chart shows the differences in the age of master of different sounds in isolation. The numbers are the ages and the sounds in those blocks are the sounds that a child should be working on at that age. All the sounds below the child’s age they would have been expected to have mastered.
How is vocabulary development affected by learning two languages at an early age? While differences begin to emerge after age 4, there are quite a few developmental similarities at the younger ages. Here are a few: • Vocabulary:– 12 months – first words (usually labeling familiar objects, actions, and properties in child’s environment)– 15 months – 4-6-word vocabulary– 18 months
Here is a list of early language milestones that occur regardless of home language • 0-1 month – crying and vegetative sounds • 18 months – symbolic play, pretend play • 24 months – sequencing of activities • 36 months episodic play • Joint turn-taking • Eye gaze • Joint Attention • Gestures • Vocalizations • Comprehension • Play
We got a question about what speech acquisitions norms to use. The truth is that a lot of different research that has different timeframes for sound acquisition. Lisa Bedore at the University of Texas compiled most of the available research in one table. I attached some of the forms that we use here in Central Texas that comes from some
