IPA's and Their Systems

Smart phones are a constant stable item we use in our day to day life. There are many brands like Apple, Samsung, Android phones etc. A few come with a IPA,or a intelligent personal assistant. Some examples of this are Amazon's Alexa, Microsoft's Cortana, Google, or Apple's Siri. The one i think that could use a bit of a tune up out of the IPA's is Siri. Siri stands as a weak link out of the personal assistant's. Siri is limited to what terms it can respond to because of the fact that it does not use a search engine to help with their knowledge database. This issue could be fixed if Apple came up with their own search engine but i think its a bit to late in the game for them to do so. Google has quite the stable in the search engine market. Microsoft even has bing however not many use it as much as Google's. Siri has a few other issues as well but the main flaw with it is that it has a hard time understanding commands compared to other IPA's. If Apple could update siri to where it could use a search engine to search for responses faster I think it would make siri one of the best IPA's or at least compete with Google and Amazon. Another flaw i think not only siri has but most IPA's have is that their voices feel robotic and I think if they gave them somewhat more human sounding voices it would help in general. I think they would be even more popular and be used a bit more if they did that.
