Experimental check-in task — not a cleared or approved medical device. This task records neutral measurements for you to keep and share. It does not score you, does not say what any number means, and does not diagnose. Only a clinician can interpret it.

What this task looks at

This task looks at sustained voice — you hold a vowel sound or say a short own-authored phrase, and it records simple sound measurements.

What you'll do

Three short voice activities, such as holding a vowel and saying a phrase. Before recording, Lantern asks for microphone consent, processes audio on your device, and lets you choose whether to keep a recording or only the measurement. Deleting is straightforward.

What it records

Neutral sound measurements:

  • Phonation duration — how long you sustained the sound, in seconds (s).
  • Pitch and loudness stability — figures describing how steady the sound was.

Each is shown with its units and the method version used, plus a short note on what the task looked at. These describe the sound only.

What it does not do

It does not tell you whether your voice or speech is normal, worse, or a sign of anything. It records sound numbers; your clinician interprets them.

Not the same as

This is an original, own-authored task. It is not and is not equivalent to a clinical dysarthria assessment or any licensed voice or speech battery. This task does not reproduce them.


Experimental. Not a cleared or approved medical device. Audio is processed on-device with your consent; you choose whether to keep it. Records neutral measurements only — no diagnosis, no interpretation.

Each task records one kind of neutral measurement — for reflection and conversation with a clinician, never a diagnosis.
