<![CDATA[General Background Regional languages function as fundamental identity markers and essential mediums for transmitting local knowledge systems across generations. Specific Background The Konjo language serves as a crucial cultural instrument for the Ammatoa Indigenous community, maintaining ancestral values and social harmony against rapid modernization. Knowledge Gap Existing literature predominantly addresses the cultural and environmental isolation of the Ammatoa area, leaving a critical void in comprehensively evaluating their sociolinguistic resilience using standardized global metrics. Aims This study investigates the vitality level of the Konjo language using nine established UNESCO indicators and identifies pressing preservation challenges. Results A mixed-methods approach integrating questionnaires, interviews, observations, and focus group discussions revealed an overall language vitality index of 0.81, categorizing the dialect as safe. However, specific indicators, particularly community attitudes and documentation quality, scored alarmingly low, indicating severe vulnerability driven by globalization, educational shifts, and reduced youth engagement. Novelty This research provides the first joint-display measurement of Konjo language vitality, uncovering hidden endangerment threats beneath its seemingly stable intergenerational transmission. Implications These findings necessitate immediate, community-based revitalization strategies, including rigorous digital archiving and the integration of traditional oral literature into formal educational curricula, to ensure long-term linguistic survival. Highlights The evaluated dialect achieved a safety index of 0.81 using standardized global metrics. Documentation deficits coupled with shifting youth preferences present significant threats to long-term linguistic survival. Strategic recommendations emphasize digital archiving alongside integrating traditional oral literature into formal educational curricula.
