Gender affects speech recognition accuracy rates
A small study found a significantly higher rate of transcription errors in women compared with men using a commercial voice recognition application. Causes of the discrepancy may include the differences in the volume and frequency of speech between sexes or more fundamental differences in how the application was tested at time of development.
A small study found a significantly higher rate of transcription errors in women compared with men using a commercial voice recognition application. Causes of the discrepancy may include the differences in the volume and frequency of speech between sexes or more fundamental differences in how the application was tested at time of development.
Dr. Syed Mahmood Ali, a radiology resident at the University of Maryland Medical Center, and colleagues trained five male and five female radiology residents on a speech recognition system. They asked each resident to dictate a standardized set of 10 radiology reports containing a total of 2123 words. The generated reports were compared with the original reports, and error rates were calculated. Researchers defined the error rate as the sum of the number of word insertions and deletions divided by the total word count for a given report.
Error rates in the male population ranged from 0.025 to 0.139, with a mean of 0.082. Error rates in the female population ranged from 0.015 to 0.206, with a mean of 0.100.
"These error rates may have significant negative impact on reporting accuracy and output, disproportionately affecting female radiologists," Ali reported at the American Roentgen Ray Society meeting.

April 24th 2024One of the recommendations from the European Society of Breast Imaging (EUSOBI) is annual breast MRI exams starting at 25 years of age for women deemed to be at high risk for breast cancer.
Study Reveals Benefits of Photon-Counting CT for Assessing Acute Pulmonary Embolism
April 23rd 2024In comparison to energy-integrating detector CT for the workup of suspected acute pulmonary embolism, the use of photon-counting detector CT reduced radiation dosing by 48 percent, according to newly published research.
