Why voice works

Speech is a complex neurological process that involves several interconnected brain functions, including memory, executive function, language processing, motor control, emotion, and attention. Because speaking relies on so many systems working together, even small changes in brain function can influence the way a person talks.

What we measure

We analyze non-content features of speech, including:

  • Timing and pause structure
  • Speech rate and fluency
  • Acoustic variability
  • Prosodic features (pitch, rhythm, stress)
  • Articulation patterns

Importantly, we do not rely on what is said, but how speech is produced.

Doctor's waits for big symptoms. Mamsa looks for early signs.

Mamsa Doctor's test (MoCA)
Use Case Ideal for proactive early and continuous cognitive health monitoring. Best for diagnosing MCI or dementia in a clinical setting.
How it works AI analyzes voice patterns (e.g., tone, hesitation) to detect subtle changes. Structured tasks to assess memory, attention, and more.
Ease of use ~1 minute test of natural speech done remotely. 10–15 minutes of structured tasks done with a clinician.
Accuracy in Early Detection Detects subtle cognitive changes early through voice analysis. Highly sensitive but better for later-stage detection.
Long-term use Ideal for continuous monitoring of cognitive health. One-time evaluation not designed for ongoing use.
