Voice Assistants as Consultants for Male Patients with Sexual Dysfunction: A Reliable Option?
Autor: Napolitano, Luigi; Barone, Biagio; Spirito, Lorenzo; Fernández Pascual, Esaú; Manfredi, Celeste
Resumen: The aim of this study was to evaluate the ability of Google Assistant, Alexa, and Siri to
recognize and answer questions about male sexual health. Each VA was tested on a smart speaker:
Alexa on Amazon Echo Dot 4th Gen., Google Assistant on Google Home Mini, and Siri on Apple
HomePod. A pool of patients’ frequently asked questions regarding erectile dysfunction (ED),
premature ejaculation (PE), Peyronie’s disease (PD), male infertility, and other aspects of male sexual
health were identified by authors. The recognition of question was evaluated (“yes” or “not”). For
each recognized question, the response characteristics (domains) were rated on a scale from 0 to 10
(according to the quality). We chose the recognition rate of the questions as the primary outcome and
the quality of the answers as the secondary outcome. Overall, the best VA in recognizing questions
was Siri, with a total of 83.3% questions compared with 64.0% for Alexa (p = 0.024) and 74.0% for
Google Assistant (p = 0.061). Siri was associated with a significantly higher recognition rate than
Alexa for PE (80% vs. 40%; p = 0.002) and PD (66.7% vs. 33.3%; p = 0.010). The quality of the
responses was classified as low in 57 out of 105 cases (54.3%), intermediate in 46 cases (43.8%), and
high in only 2 cases (1.9%), highlighting an overall intermediate-low quality of the answers. Male
infertility was the condition associated with the highest mean scores in “Targeted response to the
problem” (7.32 2.57), “Scientific correctness of the answer”, (5.9 2.76) “Completeness of the
answer” (5.14 2.56), and “Understandability of the response for a patient” (5.3 2.51) domains.
Siri was associated with significantly higher scores than Alexa (p < 0.05) in several domains of all
conditions evaluated. The question recognition rate of VAs is quite high; however, the quality of
the answers is still intermediate-low. Siri seems superior to Alexa in both question recognition and
response quality. Male infertility appears to be the sexual dysfunction best addressed by VAs.
