Acoustic Breath Biomarker Tracker

This experimental helper calculates a pause ratio from synthetic, pre-segmented durations. It does not capture audio, run VAD, detect a medical condition, assess patient safety, or execute a handoff. Its DYSPNEA_DETECTED, NORMAL, and action enums are illustrative legacy labels, not clinical conclusions. Do not use this prototype for patient triage or emergency decisions.

Scientific Foundation

How it works

1. Supply synthetic AudioSegment durations to the helper.
2. Audio capture and VAD are not included; any future host would provide its own inputs.
3. The process_call_stream function evaluates the extracted segments.
4. A pause ratio at or above the illustrative threshold selects the legacy DYSPNEA_DETECTED enum; it does not establish dyspnea.
5. ESCALATE_TO_HUMAN is returned as a demo label only. No workflow is halted and no nurse transfer or emergency handoff occurs.

Expected Outcomes & Metrics

The figures below are unvalidated design aspirations, not clinical sensitivity, specificity, or handoff guarantees.

Limitations & Known Constraints

• Codec Degradation: Low-bitrate connections may obscure acoustic pauses or falsely introduce silence gaps (packet loss).
• Background Noise: Heavy environmental noise might be misclassified as speech by VAD, lowering the calculated pause ratio.
• Not a Clinical Tool: This is not a diagnostic or patient-triage mechanism. Low scores do not establish that a person is safe.

Possible Future Research Contexts

These contexts require separate clinical evaluation and human-governed systems; they are not supported patient-care uses of this prototype.

• Post-discharge monitoring for COPD or heart failure patients.
• Daily check-in phone calls for patients with severe asthma.
• Triage in automated telehealth intake systems.

Integration

No dialogue-model or telephony integration is included. For a future host, this numeric demonstration must not delay human review or override an explicit report of distress.
