Voice-enabled smart speakers are set to become one of the most quickly-adopted consumer electronics products in history, with the devices expected to reach 25% penetration of the U.S. market by the end of the year. 

Amazon (AMZN - Get Report) has a myriad of Alexa-powered Echo products, Alphabet's (GOOGL - Get Report) Google has its Google Home suite of devices including the newly-released Home Hub and Apple (AAPL - Get Report) has its Siri-enabled HomePod speaker. And you can bet that all these devices will be sold aggressively on Black Friday, Cyber Monday and into the rest of this year's holiday season. 

Why are the tech giants investing so much in these devices and the technology that powers them? Listen to our Technically Speaking podcast below with Fresh Digital Group CEO Doug Robinson and TheStreet's Annie Gaus for an in-depth discussion of the forces driving this important market.
