Languages differ from one another in many ways. This website focuses on how aspects of speech (e.g., consonants, vowels, syllables, tones) differ between languages.
The following table includes summary resources to enable speech-language pathologists (SLPs) to compare languages.
It is useful to have a copy of the International Phonetic Alphabet to assist with interpreting the information provided in the table below.
More extensive descriptions of languages and speech acquisition data are available in Phonological Development and Disorders in Children: A Multilingual Perspective (Zhu Hua & Dodd, 2006), the International Guide to Speech Acquisition (McLeod, 2007), and on a companion page on this website:
Information about speech assessments in languages other than English is found on companion pages on this website
