They're the same thing, actually. Here:

True Tones is Asura's Semblance. It allows her to detect how a person is really feeling from the tone of their voice. It's an ability that she can turn on and off at will, though she usually keeps it on except while fighting.

Her Semblance may seem like one where she can immediately tell when a person's lying, but it's not. For Asura is still young, and no one can know everything. In other words, there are times where Asura isn't really sure if someone is lying or not, which is why she studies social behaviors a lot. It's also almost useless against those who have been trained to lie.
