This research analyzes segmental pronunciation errors made by fifth-semester students in the English for Tourism class of the English Education Study Program at Kuningan University. The research employed a qualitative method design with a case study. Data were collected through 10 video recordings, totaling 50 minutes, of the students' performances during the practice of being a tour guide. The recorded data were subsequently analyzed with the Praat software as an acoustic measure of segmental pronunciation errors. The finding indicates that the students made various segmental pronunciation errors, particularly vowels 62%, diphthongs 22%, and consonants 16%. The most frequent errors were made in pronouncing vowel sounds, particularly /ɪ/. These errors in pronunciation are perhaps due to the interference of the students' mother tongues (Indonesian or Sundanese) and the limited exposure to native pronunciation models. In conclusion, the study recommends providing more focused pronunciation instruction, particularly on segmental features, in tourism-focused speaking classes. Segmental accuracy must be enhanced to make students more intelligible and confident in using English in workplace contexts.
