The Cigna StressWaves Test, a free online tool that analyses acoustic and semantic voice patterns to assess stress levels, has been launched by Cigna International. Ellipsis Health, a medical technology developer and leader in AI health and vocal biomarkers, collaborated on the StressWaves Test. The StressWaves Test will show the user’s stress level, which ranges from ‘Extremely Stressed’ to ‘No Stress,’ as well as a painting depicting the impact of stress on the body and mind.
