Uspanteko is an endangered Mayan language spoken by up to 6000 people in the Guatemalan
highlands. We provide an overview of the phonetics and phonology of Uspanteko, focusing on
phenomena which are common in Mayan languages and/or typologically interesting. These include
glottalized consonants (ejectives, implosives, and glottal stop), uvular consonants, vowel
length contrasts, syllable structure, stress, and lexical tone. Tone is unusual among Mayan languages,
especially in Guatemala, and the phonetic description here complements the small
handful of existing descriptions of tone in Uspanteko and within the Mayan family.
