AI Chatbot Delivers Multilingual Support to African Farmers

Empowering African Farmers with AI: The UlangiziAI Story

Summary

In a groundbreaking initiative, Opportunity International and Gooey.AI have developed UlangiziAI, a multimodal AI chatbot that provides on-demand agricultural advice to farmers in Malawi. This innovative tool leverages NVIDIA A100 Tensor Core GPUs in the Azure Cloud to process queries in both English and Chichewa, the native language of about half of Malawi’s population. By bridging the gap between farmers and critical agricultural information, UlangiziAI is transforming the lives of resource-constrained farmers in Africa.

The Challenge Facing African Farmers

Farmers in Malawi, like many in Africa, face numerous challenges. With over 80% of the population living in rural or remote areas and three in four Malawians working on or owning farms, accessing reliable agricultural advice is a significant hurdle. Government offices designed to offer such advice are often inconsistently open, and reaching these offices can be difficult due to limited transportation options.

The UlangiziAI Solution

UlangiziAI addresses these challenges by providing farmers with quick and accurate answers to agricultural questions. Developed by Opportunity International and Gooey.AI, this AI chatbot can understand agricultural-related queries sent by text or voice notes and recognize and interpret photographs. The app responds in either English or Chichewa, making it accessible to a broader audience, including those who may not read or write.

How It Works

1. Query Submission: Farmers submit their questions through WhatsApp, either by text, voice notes, or photographs.
2. Transcription and Translation: Voice notes are transcribed and translated into English using large language models (LLMs) such as Meta’s MMS Large or a fine-tuned version of OpenAI’s Whisper 3.
3. Image Analysis: Photographs are automatically routed to OpenAI’s GPT4o for analysis.
4. Data Combination: The translated text and analyzed image data are combined and used to generate vector database queries.
5. RAG Pipeline: The app queries a RAG pipeline grounded in the Malawi Ministry of Agriculture Guide to Agriculture Production Manual, a 450-page book of in-depth information focused on the specific needs of Malawian farms and farmers.
6. Answer Generation: The retriever identifies and extracts relevant data from the vector database, which is then translated back into English or Chichewa and shared with the farmer in text or audio format through WhatsApp.

Impact and Future Plans

UlangiziAI has significantly reduced the time it takes for farmers to get critical farming guidance from days to seconds. Farmers who have used the app have rated it highly, and Opportunity International plans to introduce it in Kenya, making it available in Swahili and other Kenyan languages.

Technical Challenges and Solutions

Given that Chichewa is a low-resource language, Gooey.AI had to develop techniques to optimize UlangiziAI. The company regularly updates the open-source LLMs and automatic speech recognition tools the app runs on, leveraging the near step-change improvements each successive model generation has demonstrated in understanding low-resource languages.

Key Features of UlangiziAI

• Multilingual Support: Responds in English and Chichewa.
• Multimodal Input: Accepts text, voice notes, and photographs.
• Rapid Response: Reduces response time from days to seconds.
• High Accuracy: Uses advanced LLMs and image analysis tools.
• Local Relevance: Grounded in the Malawi Ministry of Agriculture Guide to Agriculture Production Manual.

Future of AI in Agriculture

The success of UlangiziAI highlights the potential of AI to transform agriculture in Africa. By leveraging AI, NGOs and governments can develop more effective tools to support farmers, ultimately contributing to food security and economic development in the region.

The Role of AI in Bridging the Digital Divide

UlangiziAI demonstrates how AI can be used to bridge the digital divide, particularly in regions where access to information and technology is limited. By developing tools that cater to local languages and needs, organizations can ensure that the benefits of AI are accessible to all, regardless of their geographical location or language proficiency.

The Importance of Local Language Support

The support for Chichewa in UlangiziAI underscores the importance of local language support in AI applications. In regions where many people may not speak or read the dominant language, providing support for local languages can significantly enhance the usability and effectiveness of AI tools.

The Potential for Expansion

The success of UlangiziAI in Malawi and its planned introduction in Kenya suggest a broader potential for AI in agriculture across Africa. By expanding this initiative to other countries and languages, organizations can help empower more farmers and contribute to the overall development of the agricultural sector in the region.

Conclusion

UlangiziAI is a pioneering example of how AI can be used to empower under-resourced communities. By providing on-demand agricultural advice in local languages, this innovative chatbot is helping to bridge the digital divide and level the playing field for African farmers. Its success highlights the potential of AI to transform agriculture in Africa and underscores the importance of local language support and relevance in AI applications.

Conclusion

UlangiziAI is a testament to the power of AI in bridging the digital divide and empowering under-resourced communities. By providing on-demand agricultural advice in local languages, this innovative chatbot is helping to level the playing field for African farmers, ensuring they have access to the knowledge and expertise needed to improve their yields and livelihoods.
