Scientists have found a method that will make life easier for blood pressure patients. Instead of pulse measurement with blood pressure devices, a device that detects it through sound has been developed.
Klick Labs in Canada has developed an artificial intelligence-supported device that measures people’s blood pressure through sound recordings. With this method, the device recognises changes in pitch as blood pressure, even though the ear cannot hear them.
In the study, 245 people were asked to record their voices to this device 6 times a day for 2 weeks. Artificial intelligence algorithms were used to analyse hundreds of vocal biomarkers, such as pitch variations, which the human ear cannot distinguish and which enable the extraction of certain information to characterise vocal data. Hypertension could be measured with an accuracy of up to 84 per cent in women and 77 per cent in men.
EARLY INTERVENTION IN BLOOD PRESSURE THROUGH VOICE
Yan Fossat said, ‘We have discovered a more accessible way to detect hypertension. We hope that the technique will enable earlier intervention in this common global health problem.’
Details of the research were included in the journal ‘IEEE Access’.
