About SpeechSuper
What is SpeechSuper?
SpeechSuper is a deep learning-powered API and SDK platform that analyzes spoken language data across pronunciation, fluency, grammar, and vocabulary. It provides scripted, semi-scripted, and unscripted speech assessment for 8 languages: English, Mandarin Chinese, German, French, Spanish, Korean, Japanese, and Russian. Built for developers, it enables language learning apps, EdTech platforms, and test preparation tools to deliver detailed feedback on spoken language.
What problem does it solve?
Traditional language learning often lacks real-time, accurate feedback on speaking skills. SpeechSuper solves this by offering automated, scalable pronunciation scoring and speech assessment that mimics a human evaluator. It eliminates the need for manual grading and enables learners to practice anytime with instant, granular feedback on specific sounds, words, and fluency.
Who is it for?
SpeechSuper is ideal for EdTech startups, language learning app developers, online tutoring platforms, and test preparation services (e.g., IELTS, PTE). It is NOT designed for general transcription services (though it includes transcription) or for non-developer users seeking standalone classroom tools. Real use cases include building a pronunciation tutor for English learners, scoring spontaneous speech in IELTS training apps, and providing bilingual speech feedback in Mandarin-English learning systems.
