How Alexa functions ?

Alexa runs on the foundation of Data and Machine Learning. Whenever Alexa makes a mistake in interpreting a request, that mistake is used to make the device smarter. And this rapid improvement is possible due to machine learning. Its cylinder has combined capabilities of speakers, a microphone, and a small computer. The computer awakes the system and blinks it’s light, whenever the system is ON. And whenever you ask something to Alexa, it records the voice. Then it sends the voice to Amazon’s Alexa voice services, over the internet and the service converts the voice into a command it can understand. Then the system sends the output back to the device. And all these occur in just a fraction of time. But it means that if there is no internet connection then Alexa will not work.

Previously when it was launched the voice was not of any human being. Artificial Intelligence (AI) and rules of Text to Speech(TTS) were used to generate the voice. That sound was more mechanical so amazon tried to make it sound more like a human being. Now some new voices have also been added to Alexa. The “King of Cool”, Samuel L. Jackson is now the voice of Alexa. Jackson’s voice can sing Happy Birthday song for you, play music, set an alarm, and can do some other few tasks. But his voice can’t be used for shopping, reminders, lists, and some other skills. And Amazon is trying to add more varieties to the voice of Alexa. In near future, we can expect to hear different types of voices on Alexa.
