This article presents the results of a research study based on two language teaching techniques, drilling and color-coding, and their effect on the correct pronunciation of the past tense phonemes /t/, /d/, and /ɪd/ in regular verbs in simple past tense when reading aloud; the population of this study was composed of twelve young adults. Qualitative and quantitative data from two instruments: an identification tally sheet and a questionnaire were gathered. The results obtained in the pre and post-test (identification tally sheet) and the performance of the participants from the experimental groups (B and C) showed that there was a positive impact on the accurate production of the past tense phonemes when reading aloud. Lastly, this research study provides evidence to claim the teaching of drilling and color-coding techniques are useful to pronounce the past tense phonemes /t/, /d/, and /ɪd/ in regular verbs correctly.
