Most of the Flamespeaker's abilities are Ex or Su. All spellshape attacks and formulae are spell-like abilities, but the Flamespeaker's Searing Touch is a melee touch attack (rather than ranged) and specifically mentions that neither the spellshape attack nor formulae shaped with it provoke AoO's. It's still subject to spell resistance, so if we come across something with that, go ahead and roll the check for it. Formulae use somatic components, and are subject to requiring concentration rolls for certain conditions such as while in a grapple or during violent weather.
Spellshape attacks are mentioned as being equal to a spell of a level equal to 1/2 (rounded down) of the spellshaper's Shaper Level (class level in a spellshaping class), minimum 1st level and maximum 9th level. It's similar in some regards to a Warlock's Eldritch Blast.
The Flamespeaker gets around some of the drawbacks of other spellshaping classes, such as not provoking AoO's, but their ability to do any kind of harm at range is limited, and all of their formulae deal fire damage unless something else in the formula specifically does a different kind. Eventually they can bypass fire resistance and part of immunity, given that it's so prevalent and they're so focused.
