| Summary: | The developed system incorporates computational intelligence, this allows to identify people with
respiratory distress (caused by influenza) in an automatic and non-invasive way, from the digital
processing of voice signals, integrating the calculation of acoustic, spectral, temporal and statistical
parameters, which implemented in a client-server architecture, they allow the respective analysis,
obtained as a result of the recording of two sustained vowel sounds (vowel "a" and "o"), through
the microphone of a mobile device of a Spanish-speaking population group aged between 18 and
49 years old.
The results obtained determine that for the detection of respiratory distress, the vowel "a" is more
efficient in women with a hit rate of 97.62% and the vowel "o" in men; reaching a hit rate of
96.77%. This system is expected to contribute to new support tools with potential for application
in health, to promote biosafety protocols, especially in this context of a Covid-19 pandemic; illness
that causes respiratory distress, like the flu. |
