Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
Participants will be offered 8 sessions of behavioural voice therapy, either immediately (experimental group) or following an 8 week delay (comparison group).

Behavioural voice therapy will target vocal hygiene information and counselling, indirect voice therapy targeting abdominal breathing and laryngeal relaxation, and direct voice therapy targeting easy onset phonation and resonant voice therapy.

Behavioural voice therapy will be administered one-on-one by a speech pathologist, in the presence of a caregiver to promote without session carryover of the therapy tasks.

Sessions will last for one hour and be administered once per week for eight weeks. In the event of cancellations and postponements, the therapy period will be extended to ensure that each participant receives the entire therapy over eight sessions.

Allocation to intervention
Non-randomised trial
Procedure for enrolling a subject and allocating the treatment (allocation concealment procedures)
Participants for this trial will be recruited from Phase I - Clinical voice assessment (quasirandomised recruitment) and Phase II - Fribeoptic Endoscopic Evaluation of Laryngeal Function (self-selection) and then randomised to either the experimental or control groups.
Methods used to generate the sequence in which subjects will be randomised (sequence generation)

Other design features
All participants will receive intervention. The experimental group will commence intervention immediately after randomisation, and the control group will receive therapy 8 weeks after randomisation to allow comparison of voice quality with and without intervention.
