In today’s rapidly advancing technological landscape, the fusion of artificial intelligence (AI) with language learning offers unprecedented opportunities for educators and learners alike. Below, I outline a beginner’s guide to developing a Generative Pre-trained Transformer (GPT) specifically designed for enhancing interpersonal speaking skills in world languages. This guide is tailored to innovators, educators, and technologists eager to explore the intersection of AI and language education. Let’s start with a short video example of Clara, a GPT that I created for intermediate students learning Spanish.

Meet Clara.

Step 1: Define Your Objective
Begin by identifying the core purpose of your GPT. Is it to facilitate conversational practice, improve pronunciation, or enhance cultural competency? For this project, the focus was on creating interpersonal dialogues in Spanish to mimic real-life interactions, providing a more natural and engaging learning experience.

Step 2: Choose Your Language(s)
Decide on the language or languages your GPT will specialize in. Starting with one language allows for focused development and refinement. Spanish was chosen due to its global significance and the personal familiarity it offered, making it an ideal candidate for the initial phase of the project.

Step 3: Leverage Existing Technology
For me, ChatGPT was an easy choice. Utilize accessible AI platforms such as OpenAI’s GPT to build your model. These platforms offer user-friendly interfaces and comprehensive support, making it easier for individuals without extensive backgrounds in AI to create effective models. Start by downloading the ChatGPT app on a mobile device as the desktop browser does not currently have speaking and listening functionality.

Step 4: Customize Language Proficiency Levels
Integrate language proficiency frameworks, like the ACTFL guidelines, into your model to tailor its speaking capabilities. This ensures your GPT can adapt its dialogue complexity and content according to the learner’s proficiency level, providing a personalized learning experience.

Step 5: Incorporate Cultural Context
Since communication is rooted in culture, I wanted to give Clara a cultural story and background. You can enrich your GPT by embedding cultural knowledge and context into its database. For Clara, a fictional heritage from El Salvador was created to infuse conversations with cultural references and insights, making the learning experience more immersive and meaningful.

Step 6: Test and Refine
Enter the beta testing phase to evaluate your GPT’s performance. This involves testing to identify any issues related to conversation flow, tone and cultural accuracy. Use the feedback to refine your model accordingly.

Step 7: Share and Gather Feedback
Once your GPT is ready for a broader audience, share it with educators, learners, and peers by adding it to OpenAI’s GPT repository and store. Collect feedback on its usability, effectiveness, and areas for improvement. This collaborative approach not only enhances the model but also fosters a community of innovation.

Step 8: Iterate and Expand
Based on the feedback and your observations, continue to refine your GPT. Consider expanding its capabilities to include additional languages or more advanced conversational scenarios. The development of a GPT for language learning is an ongoing process that evolves with technological advancements and user needs.

By following these steps, you can create a GPT like Clara that offers an engaging, interactive, and culturally rich platform for language learners to enhance their interpersonal speaking skills. The fusion of AI with language learning not only opens up new educational possibilities but also paves the way for a more interconnected and understanding world.
