Among the virtual assistants, Google is better than Alexa (Amazon) and Siri (Apple) with drugs: it contains names almost twice as accurate and can, therefore, provide more relevant information. To test vocal “butlers” is a Klick Health study published in the journal Nature Digital Medicine.
From acetaminophen (paracetamol) to Zantac, the researchers gave the assistants the name of 50 brand-name and generic drugs, spoken by 46 Englishmen with different accents. Google included 92% of drugs and 84% of generic medicines. Siri recorded respectively 58% and 51%, Alexa 55% and 45%. Google is also the one who understands the best foreign accents.
Among the curiosities, the three assistants very well understood some words such as “Aspirin,” but Alexa was experiencing significant difficulties with others, for example, ibuprofen. The word had a 100% understanding rate with Google, 59% with Siri, and 4% with Alexa.
Overall, according to the researchers, the accuracy of speech recognition technology in the medical field is expected to increase further. “Digital voice assistants are becoming popular health information tools, so their lack of understanding exposes them to mediocre, inconsistent and potentially dangerous advice,” said Yan Fossat, vice president of Klick Labs. , co-author of the study. “Some research results are encouraging, but additional efforts are needed to ensure the health and safety of people.”
