Speaker verification tools
Five distinct tools separate resistance/continuity, audio generation/drive, supplied energy and acoustic measurement. Each needs its own making and calibration route.

Capability requirements and tolerances
Consumer-specific numerical targets, quantities and acceptance limits remain open or incompletely reviewed. No smartphone-grade suitability is claimed. Distinct capability tiers require their own making route and qualification.

Making outline
- Build and calibrate the individual instruments against appropriate references.
- Check coil continuity and DC resistance.
- Supply controlled audio signal through a powered amplifier.
- Measure acoustic response, impedance/distortion and free movement/rub-buzz against chosen limits.
What remains unresolved
- No instrument circuits, ranges, accuracy budgets, calibrated standards or numerical acceptance limits are supplied.
- Reference production and measurement bootstrap are unresolved; reciprocal validation must not create prerequisite cycles.
