•3\)Ability to complete self\-reported questionnaires (PDQ\-8, VHI\-10, EAT\-10, HARQ, and CETI\-M) by written completion of the questionnaires or oral report. Carer support can be provided.
•\*Criteria for Lee Silverman Voice Therapy (LSVT LOUD)
•a)Motivated and able to commit to intensive therapy
•b)Adequate hearing
•c)Adequate cognition and memory
•d)Positive results on stimulability testing suggesting likely response to treatment (is the people able to improve loudness and quality? Can they achieve sustained vowel phonation, high and low pitch slide on ‘ah’ and functional phrases?)
•e)Socially active and keen to increase participation
•f)Otolaryngologist assessment reporting no contraindications to treatment.

•1\)People with PD without voice dysfunction.
•2\)Diagnosis of atypical PD.
•3\)Speech or voice disorder unrelated to PD.
•4\)Vocal pathology requiring alternative treatment e.g. surgery
•5\)History of neurosurgical treatment.
•6\)History of laryngeal surgery or pathology.
•7\)Previous history of head and neck radiotherapy treatment
•8\)Co morbidity affecting swallowing ability eg. cerebrovascular accident, neurogenic dysphagia of other aetiology, post\-surgical dysphagia, infective dysphagia or dementia, active tumour in larynx/ oesophagus, or Zenker’s diverticulum.
•9\)Currently pregnant, as evidenced by a positive result on a pregnancy test if the people are within child bearing age (younger than 45 years of age).
