FluentSphere helps non-native English speakers rehearse the work conversations that matter: job interviews, presentations, client calls and negotiations. Pick a scenario and talk it through out loud with a voice partner that replies in real time, then get word-by-word pronunciation scores and a breakdown of pronunciation, vocabulary, grammar, fluency and coherence.
