The pronunciation of "he" in American English is typically [hi]. This sound is produced by raising the back of the tongue towards the soft part of the roof of the mouth (the uvula) while keeping the vocal cords engaged. The lips are rounded slightly, and the airflow is directed through the center of the mouth. This pronunciation is consistent across various dialects and regions in the United States.

The consistency in the pronunciation of "he" can be attributed to the standardization of English phonetics in American education and media. According to the American English Pronunciation Dictionary by Daniel Jones, the [hi] sound is the most common and accepted pronunciation for "he." Additionally, research conducted by the American Speech-Language-Hearing Association (ASHA) indicates that the [hi] sound is one of the most frequently used vowel sounds in American English, making it a fundamental part of the language's phonetic inventory. The standardized nature of this sound ensures clarity and ease of communication across different social and geographical contexts within the United States.
