Project description

Langcraft is a deep-learning-based pronunciation diagnostics API for language-learning platforms, assessment providers and educational institutions. The project addresses a gap in spoken-language learning: current pronunciation tools often provide generic scores or transcription-based feedback without explaining what changed in the speech signal or how learners can improve. Langcraft instead analyzes learner and accented speech through interpretable acoustic and articulatory features, helping convert time-aligned diagnostics into precise, actionable feedback.
