Many tech and gadget experts present at Las Vegas CES 2017 say that Amazon's Alexa is the breakout star of this year's tech show. This news is said to have placed Apple in a tight spot as Amazon's Alexa is threatening to take over the voice-assistance and voice-first interface it has dominated for years.

In the midst of the threat that Amazon's Alexa is posing against Siri, pundits still believe that Alexa or any other smart voice assistant/virtual assistant is still far from being competitive with Apple's Siri. It can be remembered that when Siri was introduced in 2011, all other tech companies, including Google and Microsoft, was saying that it was a wrong move for Apple to take. However, the increase in the sale of Apple devices prove these tech companies wrong.

With all the improvements that other tech companies have introduced to their voice assistant/virtual assistant, there are still some features that Siri is far and ahead. First key feature of Apple's Siri is that it is way ahead in the breadth of language category compared to all voice assistants in the market today, this includes Google Allo, Microsoft Cortana and the Amazon Alexa.

Siri also has the clear advantage in the manner it presents answers to questions that users throw at it. Also, the Apple voice assistant plays with the company's strength in accessibility and in securing the privacy of its users.

Aside from playing with its strength, Apple has also decided to bring Siri to compete within the field pioneered by other tech companies for their voice assistants. Apple has introduced Siri in its Macbooks to battle with Google and Microsoft's voice assistants on PC. Apple also took Amazon in its own game by introducing Siri in TV appliances. Apple also further expanded Siri's reach as it incorporated the smart virtual/voice assistant to its wearable products.
