<\/p>\n

Background: <\/strong>Infant babbling, including consonants, vowels, and syllables, is an important predictor of speech and language development.<\/span><\/div>\n

<\/p>\n

Aim:<\/strong> To examine vowel development in the babbling of typically-developing Persian-learning infants.<\/p>\n

<\/p>\n

Method:<\/strong> This four-month longitudinal study was conducted with eight typically developing 6\u20138-month-old Persian-learning infants. A weekly 30\u201360-minute audio- and videorecording was obtained in their homes from comfort state vocalizations of infants during mother-child interactions. Despite the presence of six vowels in Persian (\/i\/, \/e\/, \/a\/, \/u\/, \/o\/, \/\u0251\/), seven vowels (\/i\/, \/e\/, \/a\/, \/u\/, \/o\/, \/\u0251\/ and \/\u04d9\/) were identified during the babbling from a total of 74 hours of vocalizations. Inter-rater reliability was obtained for 20% of the vocalizations. The data were analysed by repeated measures ANOVA and Pearson\u2019s correlation coefficient.<\/p>\n

<\/p>\n

Results:<\/strong> The results showed that two vowels \/a\/ (46.04%) and \/e\/ (23.60%) were produced with the highest mean frequency of occurrence. Front vowels (71.87%), low vowels (46.78%), and mid vowels (32.45%) were prominent. High inter-rater reliability was obtained (0.99, p<\/em><.01).<\/p>\n

<\/p>\n

Conclusions:<\/strong> An increased frequency of occurrence of low and mid front vowels in this study was consistent with previous studies on the emergence of vowels during pre-linguistic vocalizations in other languages.<\/p>\n

<\/p>\n

Implications for children and families:<\/strong> Your child\u2019s speech develops during the first months of life. They are learning to use the building blocks of words while babbling.<\/p>\n

<\/p>\n

Implications for practitioners:<\/strong> This Persian study shows the link between babbling and vowel development providing expectations for typical development.<\/p>\n
