Trial Title: Respiratory Muscle Strength Training in Presbyphonia

Study Design Characteristics:
- Allocation: RANDOMIZED
- Intervention Model: PARALLEL
- Observational Model: None
- Primary Purpose: TREATMENT
- Time Perspective: None
- Masking: SINGLE
- Phase: None
- Number of Arms: 3.0

Eligibility Criteria:
Inclusion Criteria:~* must receive a diagnosis of presbyphonia by a trained laryngologist. The diagnosis will be given following a visual examination if the observations are consistent with the characteristics of a presbylarynx, as judged by the laryngologist.~* must be 50 years old and older.~Exclusion Criteria:~* has received voice therapy in the past year~* presents with a vocal fold pathology other than presbyphonia~* has a known neurologic or a progressive neuromuscular disease~* has a medical condition that could be aggravated by the experimental intervention, or any condition judged by the physician (Dr. Halstead) as being unsuitable for RMST.~* has dysarthria or a language disorder~* has a hearing loss that is not adequately managed~* has a cognitive disorder that might affect treatment compliance~* is unable to give informed consent

Study Arms:
- Inspiratory Muscle Strength Training (Type: EXPERIMENTAL): The participants in the IMST arm will receive, in addition to standard of care voice therapy, inspiratory muscle strength training (IMST).~The IMST intervention will consist of 5 sets of 5 breaths in the inspiratory threshold device every day during four weeks, with a loading dose set at 75% of the participants' maximal inspiratory pressure (MIP). MIP will be measured once a week during the weekly supervised session to adjust the inspiratory trainer.
- Expiratory Muscle Strength Training (Type: EXPERIMENTAL): The participants in the EMST arm will receive, in addition to standard of care voice therapy, expiratory muscle strength training (EMST).~The EMST intervention will consist of 5 sets of 5 breaths in the expiratory threshold device every day during four weeks, with a loading dose set at 75% of the participants' maximal expiratory pressure (MEP). MEP will be measured once a week during the weekly supervised session to adjust the inspiratory trainer.
- Voice Exercises (Type: ACTIVE_COMPARATOR): The participants in the voice exercises group will receive standard of care voice therapy with a speech language pathologist, once a week during four weeks, plus daily practices.

Based on this trial design, predict the completion outcome and termination type (if applicable).
