PROBES snapshot: Longa, automated speech recognition for Bantu languages

This one-page brief, developed by the Digital Transformation Accelerator (DTA) team at the Alliance of Bioversity International and CIAT, is based on the Longa probe led by Eliot Jones-Garcia, Senior Research Analyst at IFPRI. The probe explores the use of automatic speech recognition (ASR) for Bantu languages to enable voice-based interaction with digital agricultural services. Longa tests whether low-resource ASR models can accurately capture farmers’ spoken input in real-world conditions and convert it into usable data for digital extension and advisory systems. Implemented as a safe-to-fail, early-stage experiment, the probe focuses on learning how voice-first technologies can reduce literacy and language barriers, improve inclusivity, and strengthen farmer engagement. The brief synthesizes key insights on accuracy, usability, and scalability to inform future development and potential integration of speech-based tools within CGIAR digital pathways.
