As a part of our continuing efforts to understand the ways and speed at which artificial intelligence enters our everyday lives, we reexamined two home assistants based on a study we performed in February. The two most popular assistants, Google Home and Amazon Echo were put to the test, this time substituting the Echo with the Echo Show, which includes a 7″ touchscreen.
Methodology. For this experiment, we asked the same 800 queries of both the Echo Show and Google Home, similar to our first study. We graded the queries on two metrics: First, did the device understand what we asked correctly? Second, did the device answer the query correctly? In our study, Amazon’s Echo Show understood 95.88% of the queries we asked and answered 53.57% of all queries correctly. Google Home understood 94.63% of the queries we asked, but was able to answer 65.25% correctly. Below, you can see the improvements that each home assistant made since our last set of queries.
One advantage the Amazon Echo Show has when it comes to understanding queries is that we have the ability to confirm the data using Amazon’s companion app. This app gives the user a live feed of what Amazon Echo Show heard. Google Home does not offer a transcript of what it’s home assistant device picked up. Because of this, it was difficult to tell if Google Home understood the queries but couldn’t answer them, or if it truly had a harder time understanding queries. Since we were unable to see exactly how well Google Home understood our queries, we assumed that if Google Home responded that it was unable to perform a certain function, then it had understood the query correctly. For example, if we asked, “Hey Google, send a text to John” and received a response “Sorry, I can’t send texts yet,” then the query would be marked as understood correctly, but answered incorrectly.
Results. Both home assistants showed increased performance across the board. This time the Google Home outperformed the Echo in total number of correct answers by nearly 12 percentage points, up from a 5 point performance gap in our February results. While each digital assistant has its strengths and weaknesses, Google Home outperformed its rival in 3 of the 5 query categories by a surprising margin. This is significant because it shows not only rapid improvement, but outperformance of Amazon who has both a 2-year head start and a near 70% market share vs. Google’s 24% share of the home assistant market, according to eMarketer.
Both Home Assistants Notably Improved in Navigation. The most dramatic increase for both assistants was in navigation. In February, over 90% of navigation questions were answered with: “I can’t help you with that.” Today, navigation is the best category for both the Google Home and the Echo Show, with the Google Home answering 92% of queries correctly, and the Echo Show answering 63% of queries correctly.
Echo Show: Screen adds to experience, but software upgrades drive improvement. The Echo Show’s camera and touchscreen allow it to make video calls, monitor your security cameras, visually display some forms of information, and introduces new use cases with Alexa Skills that incorporate a screen. For instance, you can say, “Alexa, show me the trailer for the new Spiderman movie,” or scroll through recommendations for local pizzerias. While this adds to the user experience, the addition of the screen itself isn’t driving all of the improvement that we are seeing with Alexa. Instead, numerous software updates have increased the way Alexa can contribute to our daily lives. The Echo Show had a near 20% improvement in its ability to answer both local questions (“Where can I find good barbecue?”), and respond to commands (“Cancel my 2:00 p.m. meeting tomorrow”). Both of these changes are driven by software improvements, not the addition of the screen.
Google Home: Quickly adding features to pass Alexa. Google Home improved its local and commerce results by 46 percentage points and 24 percentage points, respectively. This represents a broadening of its skills along with high navigation, information, and local scores. Google Home also supports up to 6 different user accounts, meaning your whole family can get personalized responses when you say, “Okay Google, what’s on my calendar today?” Google Home will recognize your voice and read your upcoming events. Separately, commerce is an area that was previously dominated by Amazon, but Google is now at parity, mainly due to its superior ability to understand more diverse natural language. While Alexa still has a larger database of add-on skills, Google Home outperformed in our set of queries.
Future home assistant competition looks intense. While Amazon and Google are the current frontrunners in the home assistant race, they are facing competition from several notable future entrants:
- Apple HomePod (expected December 2017)
- Alibaba Tmall Genie (released August 8th, 2017)
- Microsoft Invoke (expected Fall 2017)
- Lenovo Smart Assistant (utilizing Alexa, expected Fall 2017)
- HP Cortana Speaker
- Samsung Vega
Persisting Problems of Home Assistants. While home assistants continue to make noticeable improvements, we still believe that they are in the early innings of a platform that will become an important part of computing in the future. That being said, there are small, technologically reasonable improvements that we would like to see from these products. Our main complaint is the lack of integration with devices to make use of information or take further action. In most cases, the fastest way to get information to a user is on a screen – it’s hardly convenient to have a list of 10 restaurant recommendations read to you one at a time. Instead, you should be able to call up information verbally and have it sent to your smartphone, computer screen, or television. The Echo is able to interact with your phone via the Alexa app. Google Home can control a Chromecast. Both are able to control certain smart home devices. There is clear progress being made on this front, but it remains a key obstacle to the devices’ effectiveness. Another shortcoming that persists is unsatisfactory natural language processing, an added barrier to widespread use. Both assistants were selective in the way you had to phrase a question in order for it to be answered correctly. For example, Google Home will understand, “What is a gigawatt?” but cannot process, “Google gigawatt.” or, “Tell me what a gigawatt is.” In order for digital assistants to reach widespread adoption, users need to interact with them seamlessly.
Overall, we were impressed by the improvement that took place in a few short months and remain optimistic that the technology will continue to advance at this pace going forward. As new players enter the space and homes become more connected, the technology in these devices will be increasingly important in our everyday lives. Later this year we will track the further progress made by the Echo and the Home, and compare them to some of the new entrants set to arrive by the end of 2017.
