Development of an AI-Powered Multilingual Language Learning Tutor with Speech Recognition and Error Analysis

The client requires an advanced language learning solution capable of engaging users in natural conversations across multiple languages (English, Spanish, and German). The current platform lacks an AI assistant that can understand speech, detect grammatical mistakes, and provide clear explanations, resulting in reduced user engagement and learning effectiveness.

A mid-sized educational technology company offering digital language learning tools seeking to enhance their platform with interactive AI-driven tutoring features.

• Implement an AI-powered chatbot that can comprehend natural speech and maintain context-aware conversations in multiple languages.
• Integrate speech recognition capabilities to enable seamless spoken interactions without manual typing.
• Develop an error detection system capable of analyzing user inputs for grammatical mistakes.
• Create an explanation module to provide detailed feedback and educational insights on errors.
• Seamlessly embed the AI tutor into the existing eLearning platform to enhance user engagement and learning outcomes.
• Improve user engagement metrics, aiming for at least an 11% increase in active participation within the first month of deployment.
• Enable scalability to support a broadening language portfolio and future feature expansions such as pronunciation analysis.

• Advanced speech recognition to transcribe spoken language in real-time using models like Whisper AI.
