Document Summary
She exposed american and swedish babies to either english or swedish vowel sounds. But at the very least, you can test for recognition. They played very loud sounds (100-120db) close to the abdomen of a pregnant mother. Expected babies to move and heart rate to increase. At 6 months of gestation, nothing happens (i. e. , no reaction: auditory system if formed, not necessarily connected. But around 7-9 months, they get a change in heart rate. Length of sucking = length of exposure to language.

Preference for non-native vowels suck more for the non-native vowels. Babies also suck more and react more when vowels change. We can at least see that they can tell the difference between the sounds since they react differently to usual and new vowels.
