Language Confidence

Language Confidence offers a sophisticated AI Speech Assessment Toolkit through its API, designed to automate the teaching and testing of spoken English for students. This toolkit provides detailed feedback on pronunciation, fluency, grammar, and vocabulary, along with estimated scores for recognized English tests. The system can identify errors down to the phoneme level, providing on-demand, real-time feedback and unlimited practice opportunities. Available in three products—Pronunciation API, Scripted API, and Unscripted API—it is a fast, reliable, and cost-effective solution for assessing spoken English skills.

The toolkit includes detailed metrics for each skill: pronunciation covers phoneme, word, and overall scores, with detection of low-scoring phonemes; fluency assesses speech rate and variation, filler words, disfluent pauses, and connectives; grammar provides a complexity score and detailed mistake analysis with suggested fixes; vocabulary evaluates complexity, detects idiomatic expressions, and assesses relevancy. This comprehensive feedback system aims to enhance students' spoken English abilities efficiently and effectively.
