ROI Calculation Logic

Assuming a 25% reduction in manual correction time for ambiguous word misinterpretations in multilingual call centers and content production. For 100 workers with an annual personnel cost of $33K/worker (AI est.), the total annual personnel cost is $3.3M (AI est.). A 25% reduction yields $0.8M (AI est.). Including reduced opportunity loss from improved customer satisfaction, an estimated annual economic impact of ~$1M is projected.
