Elara DeschampsJosh Groban and Jennifer Hudson will kick off their joint North American arena tour in Montreal on June 2, 2026, with a sold-out stop at Toronto's Scotiabank Arena on June 4 — and for two of the most recognizable voices in contemporary music, the 16-date run raises a question well worth examining: what does it actually take to protect the human voice through a month of arena performances?
The duo's GEMS 2026 tour, produced by Live Nation, spans major arenas across the US and Canada through July 3. For Canadian fans, and for anyone who depends on their voice professionally, the announcement is a timely reminder that vocal health is a medical concern — not just a performer's preoccupation.
A 16-Date Arena Run: What That Demands of the Voice
Performing in a 20,000-seat arena is physically unlike anything that happens in a recording studio. The human voice depends on the vibration of two small muscular folds — called the vocal cords — that can vibrate up to 300 times per second at higher pitches. In a live arena setting, ambient noise, air conditioning systems, and stage monitor placement create acoustic conditions that force singers to push harder and sustain longer than in controlled environments.
Over 16 shows across 32 days, that level of vocal output — even for performers with decades of professional training — creates a significant physiological load. Groban, known for his operatically trained baritone, and Hudson, a Gospel-rooted mezzo-soprano, both rely on vocal technique that requires ongoing maintenance, rest, and specialist oversight.
The Voice Disorders ENT Specialists See Most Often
Ear, nose, and throat (ENT) specialists — formally called otolaryngologists — are the physicians who diagnose and treat vocal fold conditions. According to ENT Canada (the Canadian Society of Otolaryngology Head and Neck Surgery), voice disorders are among the most common conditions seen in performing arts medicine, with several recurring patterns:
Vocal nodules are callus-like growths on the vocal folds that form from repeated friction — essentially the voice's version of a blister turning into a callus. They produce a hoarse, breathy quality and are more common in high-use voice professionals. Mild cases can often be resolved through voice rest and speech therapy. More established nodules may require microsurgery.
Vocal haemorrhage is an acute event: a rupture of blood vessels in the vocal fold, typically triggered by performing while ill, screaming, or a single high-effort episode. The symptom is sudden — a dramatic drop in quality or an abrupt change in vocal range. Treatment requires strict vocal rest and close ENT monitoring.
Laryngopharyngeal reflux (LPR) is frequently overlooked. Erratic eating schedules, late-night meals after shows, and the stress of touring can trigger acid migration into the larynx, causing chronic throat clearing, a persistent sensation of something lodged in the throat, and cumulative fold irritation. Many touring artists manage LPR with dietary adjustments and medication.
Pre-tour, professional performers typically receive a laryngoscopy — a brief, non-invasive visual inspection of the vocal folds — so that any existing concerns can be addressed before the performance schedule begins.
Voice Problems Are Not Limited to Performers
While Josh Groban and Jennifer Hudson travel with vocal coaches and specialist access, the underlying health concerns translate directly to everyday Canadians. Teachers, lawyers, clergy, call-centre workers, coaches, public speakers, and anyone who relies on their voice for sustained professional use are subject to the same physiology.
Voice disorders affect approximately 7 percent of the population at any given time, yet most people wait six to twelve months after symptoms first appear before seeking care. The threshold for a medical consultation is lower than many assume. ENT specialists recommend seeing a professional if you notice:
- Hoarseness or a voice quality change lasting more than two weeks
- Vocal fatigue after fewer than 60 minutes of normal speaking
- Loss of upper range or unpredictable pitch breaks
- Pain or discomfort when speaking or swallowing
- A persistent sensation of something caught in the throat
Early intervention generally yields far better outcomes. Vocal nodules identified at an early stage can often be resolved through speech therapy alone, without any surgical intervention.
What a Vocal Health Consultation Involves
A first appointment with an ENT for voice concerns typically begins with a case history — how long symptoms have been present, how the voice is used professionally, and whether there is any history of reflux, allergies, or previous throat conditions. This is followed by a laryngoscopy using a flexible fibre-optic scope, a quick and non-invasive procedure that allows direct visualization of the vocal folds.
In many cases, the ENT will coordinate with a speech-language pathologist (SLP) for voice therapy — exercises that retrain vocal mechanics to reduce strain and improve efficiency. For more complex or structural issues, the specialist may recommend video stroboscopy, which captures slow-motion footage of the vocal folds to assess vibration patterns precisely.
In Canada, the referral pathway typically begins with a GP or family physician. For faster access, private consultation with an ENT specialist is available in most major cities.
Finding the Right Specialist in Canada
If you are noticing changes in your voice — particularly changes that have persisted for more than two weeks — speaking with a healthcare professional is the right first step. Expert Zoom connects Canadians with health professionals, including general practitioners who can triage voice symptoms and refer to specialist care when needed.
Whether you are preparing to cheer at a two-hour concert on June 4 or simply noticing that your voice is not what it used to be, the vocal health expertise Josh Groban and Jennifer Hudson rely on is available to Canadians who need it. You can learn more about protecting your voice from a Canadian perspective through ENT Canada's vocal health resources, the national professional society for otolaryngologists in Canada.
