[7] Cheyenne and Navajo English, among others, follow General American patterns of glottal replacement of t, plus both t- and d-glottalization at the ends of syllables.

This is commonly stereotyped in American popular culture as a monotone, subdued, or emotionless sound quality.

[9] A 2016 study of various English-speaking indigenous North Americans (Slavey, Standing Rock Lakotas, and diverse Indian students at Dartmouth College) found that they all used uniquely shared prosodic features for occasional emphasis, irony, or playfulness in casual peer interactions, yet rarely in formal interactions.

Navajo, Northern Ute, and many other varieties of Indian English may simply never use plural markers for nouns.

Verbs like be, have, and get are also widely deleted, and some varieties of American Indian English add plural markers to mass nouns: thus, furnitures, homeworks, foods, etc.
