What’s does it mean when a girl say she likes my voice and I should do modeling?

Long story short I met a girl online and we never seen each other in person. We been texting and calling/FaceTiming for about 4 years, recently she said she liked my voice and she said I should be a model.
Like I know it’s sounds normal but does it have secret meaning behind it?
