RINCON — Becca Velasquez uses more than her mouth when she talks. Each of her words is supported by expressive eyes, hand gestures and voice inflections.An Effingham County High School senior, Velasquez also employs her heart when she attempts to engage her listeners — especially Rotary Speech Contest judges. She won this year’s contest, a joint venture between Rotary Club of Effingham County and Effingham Sunrise Rotary, at Ebenezer Retreat Center on Thursday.“Personally, I think it’s a gift straight from God,” Velasquez said.
