Reviewers largely see ELSA as a useful pronunciation practice app that works best with regular use: they praise its instant feedback, short lessons, flexible daily practice, and noticeable gains in pronunciation and speaking confidence. Several say it is especially helpful for intermediate or advanced learners, and one teacher says students enjoy using it in class. The main complaints focus on usability, especially a frustrating onboarding flow, weak interface design, and occasional speech-recognition or microphone bugs. A few also want deeper analysis and more believable scoring.
