Abstract
A recently developed self-consistent technique, based on analyticity, unitarity, and generalized ladder-graph dynamics, is used to calculate soft-meson couplings. Ladder exchanges are approximated by Regge exchanges and certain duality constraints are imposed, leading to \ensuremath{\rho}-, f-, and g-meson \ensuremath{\pi}\ensuremath{\pi} partial decay widths which are in good agreement with the data. If the dual-tree approximation for the triple-Regge vertex g(t,t',t'') is made, a value for g(0,0,0) in reasonable agreement with experiment is obtained.
