What Causes Voice Changes?
Voice changes can have various causes, ranging in severity from 'serious' to 'generally fatal'. Finding the true cause means ruling out or confirming each possibility – in other words, diagnosis.

Diagnosis is usually a complex process due to the sheer number of possible causes and related symptoms. In order to diagnose voice changes, we could:
- Research the topic
- Find a doctor with the time
- Use a diagnostic computer system.
The process is the same, whichever method is used.
Step 1: List all Possible Causes
We begin by identifying the disease conditions which have "voice changes" as a symptom. Here are two possibilities:
- Larynx Cancer
- Guillain-Barre Syndrome
Step 2: Build a Symptom Checklist
We then identify all possible symptoms and risk factors of each possible cause, and check the ones that apply:

often/always feeling unusually cold
... and so on
Step 3: Rule Out or Confirm each Possible Cause
A differential diagnosis of your symptoms and risk factors finds the likely cause of voice changes:
Cause |
Probability |
Status |
Guillain-Barre Syndrome |
94% |
Confirm |
Larynx Cancer |
67% |
Possible |

Arriving at a Correct Diagnosis
The Analyst™ is our online diagnosis tool that learns all about you through a straightforward process of multi-level questioning, providing diagnosis at the end.
In the
Mouth/Oral Symptoms section of the questionnaire,
The Analyst™ will ask the following question about recent change in voice:
Within the past few years, months or weeks, has your voice changed in any way, for no apparent reason?
Possible responses:
→ No / don't know
→ A little, I think
→ Moderately - I have had a few comments about it
→ Significantly - Many have noticed it
→ Yes, it has changed almost beyond recognition
|
Based on your response to this question, which may indicate slight voice change, voice change or major voice change,
The Analyst™ will consider possibilities such as:
