Impairment is a Silent Threat

The cost of ignoring impairment risk in high-stakes industries is staggering.

$167Bn annual cost of workplace injuries in the U.S

THE PROBLEM

43%

of workers are sleep deprived

25 min

Productivity Gain per shift

Average shift length decreased by ~25 minutes for the same work during Tenvos AI deployment, indicating improved alertness, reduced fatigue, and greater impairment awareness.

Frequently Asked Questions

What is voice impairment detection?

Voice impairment detection is a method of screening worker fitness for duty by analyzing a short voice sample with machine-learning models trained on acoustic and prosodic biomarkers associated with fatigue, alcohol, and cannabis impairment. Unlike traditional drug tests, which detect the presence of substances from past use, voice impairment detection measures the actual cognitive and physical effects of impairment in real time.

How long does a Tenvos voice check take?

Six seconds. A worker speaks into any phone, tablet, or kiosk, and Tenvos AI returns a fitness-for-duty assessment in real time. There is no game, no breathalyzer, no lab sample, and no camera required.

What types of impairment can Tenvos detect?

Tenvos detects impairment from fatigue, alcohol, and cannabis using a single voice sample. Because the system measures the effect of impairment on the worker's voice rather than the presence of a substance, it screens for multiple causes simultaneously.

How does voice impairment detection compare to drug testing?

Drug tests detect the presence of substances in the body, often days after use, and do not correlate to current impairment. Voice impairment detection measures the worker's current cognitive and physiological state at the moment of the test. It is non-invasive, returns results in real time, and does not require a lab sample.

Which industries use Tenvos?

Tenvos is built for safety-sensitive workforces in fleet and logistics, waste management, public works, construction, oil and gas, manufacturing, plants and refineries, and warehousing operations.
