I too have had this warning but in a 321.
On a visual approach, autothrust active in speed mode, Flap 3 selected maintaining F speed. Turned onto finals (low TAS produced a good rate of turn) into a strong headwind & VAPP shot up by about 15kts due to G/S mini. VAPP now about 10kts above current speed resulting in "Speed Speed" warning & a huge increase in thrust.
Thanks G/s mini that helped a lot
