This service activity aims to improve students' English pronunciation skills through the Automatic Speech Recognition Indah (ASRI) website. The platform offers interactive learning with automatic feedback to help students improve pronunciation, especially difficult consonant sounds like /ð/. Students are trained to pronounce various consonant sounds and are directly evaluated by ASRI. The results showed that the sounds /k/ and /dʒ/ were the easiest to pronounce (23/24 correct questions), followed by /tʃ/ and /θ/ (17 and 16), while /g/ (15) and /ð/ (12) were the biggest challenges. The use of ASRI has been shown to help identify specific errors and encourage consistent self-paced learning. Although its effectiveness depends on the difficulty of the sound, regular practice and feedback features from ASRI are expected to improve pronunciation accuracy significantly.
