What is baked Oolong tea?
In the art of Oolong tea processing, baking is the final step. It is also the last chance to influence a tea's composition of flavors. In the old days, processing tea was a greater effort. Traditionally, to bake Oolong, tea was placed in cylindrical woven bamboo wicker baskets that were stacked, one on top of the other, and placed over a burner. The burner held charcoal that had to be tended frequently. The person who was the Oolong baker would check on and adjust the fire in order to maintain the necessary constant temperature.

This Oolong baking method is known as charcoal baking and is still used today by those interested in preserving the art of traditional tea production. Charcoal baking of Oolong takes a great deal of time and patience and the Oolong baker has to work around an open fire, so smoke is a constant obstacle. Smoke can give a subtle smoky hint that can sometimes overpower the flavor of the tea.

You can find examples of "roast", but "baked" seems to be used more often in the context of Taiwanese oolong. See more examples here:

This baked Ti Kwan Yin style oolong has been preserved and rebaked for each of the last four years. This produces a leaf that is almost coal-black and the steeped cup is dark, toasty, very smooth, and slightly fruity and sweet.

The more I look into this question of teas, the more complex it seems, especially when it comes to oolongs! The best I can do is send you one more link, in the hope that it may help you to decide. You will find all three words here: "roast", "fire", "bake":
