Why clients choose Mark

Most accent work is built at rest. I build for performance.

I train accents and speech behaviour to remain stable as variables shift: pace, emotion, text, and time.

My work focuses on stability over imitation, structure over memorisation, and people over stereotype.

I’m Mark Byron Dallas. I work with actors and communicators who need speech that holds under pressure—through performance, pace, emotion, and change—not just in ideal conditions.
