1. A voice therapy device, comprising:
a body having an internal passageway with a longitudinal axis that defines an airflow direction;
a mouthpiece positioned at a proximal end of the body; and
a resistance portion positioned at a distal end of the body, wherein the resistance portion includes a blocking structure and one or more airflow outlets; and wherein the blocking structure is conical and symmetrical about the longitudinal axis; wherein the blocking structure extends into the internal passageway through an opening in the distal end of the body; and
wherein the resistance portion including the blocking structure rotates relative to the body about the longitudinal axis to adjust an open area between the resistance portion and the body to vary an airflow resistance through the internal passageway.
