The internet is full of videos comparing Siri to OK Google side by side and showing that after all these years Siri still hasn’t learned much. My personal experience bears this out:
When I asked Siri who built the Taj Mahal, Siri opened an excerpt from Wikipedia that had no information on its builder. By comparison, OK Google came back with the name Ustad Ahmad Lahouri, who was chief architect of the Taj Mahal.
When I tell Siri ‘Navigate to Pentagon City Mall,’ she asks which Pentagon city mall and offers two businesses within the mall. When I told Google to do the same it opened the map with directions to the mall in question.
Google does a pixel perfect job when I tell it to ‘send an email to Jennifer and tell her that I will be late.’ Google opens the mail app with Jennifer’s email ID in the address and the message ‘I will be late’ in the message field. It knows what ‘tell her’ means.
When I try the same with Siri, in 90% of the times it does not understand what I am saying. It will write something like this in the message field: ‘And does her I will be late.’ In some cases it will insert the message in the subject field.
When asked who was Mozart, while Google gave me the exact answer, Siri was looking for ‘mose art.’ When asked what is two and two, Google told me it’s 4 whereas Siri was ‘looking the web for what is two into two’.
