Using AI for OET role based conversations

Overview

The client is a group of nursing professionals preparing for the OET speaking test.

Nurses play a crucial role in patient communication, making it essential for them to have strong conversational skills. To improve their proficiency, we developed an AI-driven speaking practice platform using Gemini AI. This generative AI-powered tool allows nurses to engage in realistic roleplay scenarios, enhancing their fluency and confidence in professional conversations.

The Objective

The goal was to create an interactive system that provides real-time evaluation, time-bounded tests, and conversation-based assessments to help nurses practice effectively.

From the user’s perspective, the system should:

• Enable seamless roleplay with AI-generated characters.
• Provide real-time feedback on pronunciation, fluency, and grammar.
• Offer an engaging and interactive learning experience.
• Simulate real-world medical conversations to improve communication skills.

The Challenge

Nurses preparing for the OET speaking test often struggle with:

• Limited access to real-life speaking partners for practice.
• Lack of immediate feedback on their speaking performance.
• Inability to track their progress over time.

Traditional methods, such as offline training sessions and textbook-based learning, do not provide the level of immersion and real-time assessment needed for effective skill-building.

The Solution

We developed a web-based AI-powered OET speaking practice platform using Gemini AI and modern web technologies. The platform includes the following key features:

Key Features:

• Real-Time Roleplay: Nurses can engage in AI-driven medical conversation simulations with virtual patients.
• Text-to-Speech & Speech-to-Text: Enables seamless interaction by converting speech into text and vice versa.
• AI-Based Roleplay Card Generation: Custom roleplay scenarios are generated based on the user’s practice needs.
• Time-Bounded Tests: Simulates actual OET test conditions to help users practice under exam-like scenarios.
• Real-Time Evaluation: AI provides instant feedback on fluency, coherence, and pronunciation.
• Conversation-Based Assessment: Performance is evaluated based on interaction quality, relevance, and correctness.
• Custom Image Upload: Users can upload images to generate roleplay scenarios based on medical case studies.

Implementing the Tech Magic

The platform was built using cutting-edge web technologies, ensuring smooth and scalable performance:

• Frontend: React.js for an intuitive and user-friendly interface.
• Backend: Node.js with Express.js for seamless communication between the AI and the user.
• AI Engine: Gemini AI for natural language processing and conversation simulation.
• Cloud Hosting: Deployed on AWS/GCP for scalability and efficiency.

The Result

With the AI-powered OET speaking practice platform:

• Nurses can practice at any time with AI-generated roleplay scenarios.
• Real-time evaluation provides actionable insights for improvement.
• Users experience an engaging, immersive, and highly effective preparation method.
• The platform significantly enhances fluency, pronunciation, and medical communication skills.

This AI-driven approach to OET speaking test preparation empowers nurses to communicate more effectively, ultimately leading to better patient interactions and higher OET scores.
