The surname should be a big giveaway, but for those still unsure, let me go ahead and confirm that she is indeed the sister of Toni (and Tamar) Braxton.
Taking a similar route to her siblings, Traci is serving up Rnb with her debut song Last Call. Unfortunately, it also sounds like she's giving us a side helping of auto-tune, with some parts coming off almost robotic in tone. I could be wrong though, so don't quote me on her being computer assisted!
I guess a live showing of Last Call, or further material, will help me get a better feel for her real tone and timbre. Till then, I'll leave you all to make up your own minds.
