The study shows that teachers with voice problems can learn a voice therapy at a one-off workshop, and comply with self-administered practice at home, sufficiently well to bring about measurable improvements in self-perceived vocal performance, or in an acoustic voice parameter. This information is heartening since most teachers interviewed have insufficient time to attend weekly voice therapy, and may consider the cost prohibitive.
