According to one estimate, there are currently 8.2 million US homes with Amazon Echo/Alexa devices. VoiceLabs says that Google has sold anywhere between 400,000 and 500,000 of their Google Home devices since it first came out.
Based on these two estimates, Home and Echo have made a market that is approaching nine million “voice-first devices.” This doesn’t include inc-car or smartphone-based virtual assistants.
A report was released on January 23rd that discussed what it called the “voice-first ecosystem.” VoiceLabs has estimated that 24.5 million voice-first devices will ship this yer. This means that over 30 million total voice-powered intelligent assistants in homes across the US by year’s end. We obviously don’t know if this number will met until the end of the year, we can see that there is a market for these devices. A growing number of developers are trying to get in front of it to take advantage of it.
According to Amazon itself, there is over 7,000 Alexa skills (voice apps). The issues that Alexa is facing are that of quality and discovery. Not only that, according to the VoiceLabs report, there is a big user retention problem. This is a bigger problem than what smartphone apps are currently facing.
