Azure Speech Pronunciation Assessment

An AI-driven speech evaluation tool that provides real-time, actionable feedback on pronunciation accuracy, fluency, and prosody for language learners.

Azure Speech Pronunciation Assessment acts as a personal, scalable language coach by analyzing spoken audio against native-speaker models (trained on over 100,000 hours of speech data). It delivers immediate, objective scores across key metrics: accuracy, fluency, completeness, and prosody (rhythm and intonation). Developers can integrate this API into educational apps, gaming platforms, or corporate training systems to pinpoint specific mispronunciations down to the phoneme level. With support for both scripted reading and unscripted speaking scenarios, it provides the precise feedback loop learners need to speak with confidence.
