Voice Monitoring:

Don’t Diagnose, Don’t Treat !

At Voice Health, we are not a medical provider. We do not diagnose diseases, and we do not offer treatment. What we do is assist. Our role is simple yet powerful: we help amplify your insight.

We provide voice-based feature analysis – a non-invasive, data-driven tool that can reveal subtle patterns in vocal behavior. These patterns might reflect underlying changes in physical or mental well-being. However, interpreting these patterns and making a diagnosis is not our role – it is your expertise as a professional.

Why Voice?

The human voice can carry signs of fatigue, stress, emotional shifts, respiratory issues, and neurological changes. We extract voice features such as pitch, jitter, and shimmer to offer a consistent and objective lens for monitoring vocal health.

We do not record or store raw audio. Instead, we process the voice in real-time, extract numerical features, and discard the recording instantly. This ensures privacy and security, while still providing valuable data.

🎤 Understanding Pitch, Jitter, and Shimmer in Voice Analysis

Voice is more than just a means of communication — it’s a rich source of biometric and health-related information. Subtle changes in the voice can reflect emotional states, neurological disorders, respiratory issues, and even early signs of fatigue or depression. At the heart of voice analysis lie three core acoustic features:

1. 🟣 Pitch – The Fundamental Frequency

What is it?
Pitch refers to the fundamental frequency (F0) of the voice — essentially, how high or low a person’s voice sounds. It is determined by the vibration rate of the vocal cords.

Why does it matter?
Variations in pitch can signal:

  • Hormonal changes

  • Neurological disorders (e.g. Parkinson’s Disease)

  • Stress or anxiety

  • Fatigue or emotional strain

Example: In patients with Parkinson’s, pitch tends to become more monotonous and flat over time.

2. 🔵 Jitter – Frequency Instability

What is it?
Jitter measures the minute, rapid fluctuations in pitch from one cycle of vocal fold vibration to the next. It’s a key marker of voice stability.

Why does it matter?
Elevated jitter levels are often linked to:

  • Neurological impairments

  • Muscle tension dysphonia

  • Emotional stress

  • Vocal fatigue

Example: A high jitter value may indicate early motor control issues in the laryngeal muscles — a potential indicator in conditions like ALS or spasmodic dysphonia.

3. 🟡 Shimmer – Amplitude Instability

What is it?
Shimmer refers to variations in the amplitude (loudness) of the voice signal. Like jitter, shimmer indicates instability, but this time in volume rather than frequency.

Why does it matter?
Abnormal shimmer values can be associated with:

  • Vocal fold lesions (nodules, polyps)

  • Inflammation or swelling

  • Psychological distress (e.g., panic disorder)

  • Early signs of respiratory strain

Example: In some patients with chronic fatigue syndrome or asthma, shimmer levels may increase due to reduced vocal control.

💡 How These Metrics Can Support Professionals

When tracked over time, pitch, jitter, and shimmer provide valuable biomarkers that can help professionals:

✅ Detect early vocal changes before symptoms are perceptible
✅ Monitor response to therapy or medication
✅ Screen populations non-invasively
✅ Track the emotional or neurological state in mental health contexts
✅ Provide objective feedback to patients and clinicians

⚠️ Important Note

While these voice features are powerful, they are not diagnostic tools by themselves. They support professional evaluation — they don’t replace it.

How We Help You

Whether you’re a:

  • Medical clinic

  • Therapy center

  • Speech pathologist

  • Mental health organization

  • Research institution

Voice Health offers a complementary tool – not a replacement. We empower professionals to monitor trends, observe deviations, and make more informed decisions. You remain in charge. Our job is to enhance your process, not to take over it.

Your Expertise + Our Technology = Better Outcomes

Think of Voice Health as a stethoscope for the voice. It doesn’t tell you what’s wrong – but it lets you hear better, measure more accurately, and act faster.

We believe in collaboration, not substitution.

Together, we can deliver smarter, earlier, and more personalized care.
