As an outstanding representative of smart speaker products, Amazon Echo has been popular in the market since its release in late 2014. It is understood that in 2015, Amazon Echo sold 4 million units, and in 2016 sold 8 million units. In 2017, the sales target was 10 million units. This also makes many other smart speaker manufacturers envious.
For Amazon Echo, its core technology is its integrated intelligent voice assistant Alexa. As early as June 25, 2015, Amazon announced that it will open the voice technology of the embedded AI assistant Alexa of the intelligent voice hardware Echo for free use by third-party developers. Subsequently, Amazon released a version for third-party developers, users can control Alexa through other electronic devices, without having to pass Echo. This also gives many third-party smart speaker manufacturers the opportunity to use Alexa to create a smart box similar to Amazon Echo.
The following will introduce you how to develop a smart speaker like Echo.
Since I have been focusing on WiFi audio for five years, I am familiar with the technology of WIFI audio. So I recently received a lot of product managers from Beijing, Shanghai and Shenzhen to come to the door and find out that everyone is still studying Echo. In the past stage, this product of Echo is only staying in the understanding of Echo, a smart voice recognition sound. Therefore, today I share my technology development, resource integration, market conditions, and future development, and reduce everyone's doubts.
The history of Amazon Echo
First, let's briefly introduce Amazon's echo product, which is a product developed by Amazon for 2,000 people.
Before that, I had to mention its predecessor, SONOS Audio. SONOS Audio is a product developed and built in 2002 by the United States in 2002. The core technology members of this company came to Qualcomm, a high-tech communications company in the United States. 6 years of technical research will be WIFI's high bandwidth, high fidelity lossless transmission and decoding, multiple devices with each other (using wifi wide bandwidth, several audio connections to the same LAN to simultaneously play the same song, creating a wireless surround sound At the same time, with the technology exchange and business cooperation controlled by its music cloud service, SONOS Audio's APP integrates mainstream music content service providers in the US, China and Europe, such as Pandora, Spotify, QQ music, Shrimp, Dormy, etc. Rich content resources. The result is a high profile and substantial gains for the company. In 2005, Jobs exclaimed when he saw the SONOS sound, "This is the future of sound." Long-term technology research and development and investment (reported to invest 200 million US dollars) has brought good benefits to SONOS audio. In 2011, SONOS audio sales reached nearly 200 million US dollars.
SONOS audio has five classic products, including: three wifi stereo, a soundbar, a WIFI bridge box, WIFI central control. But its shortcomings are also obvious: expensive, large, only suitable for high-end consumer groups, and its core advantages multiroom function can only show its advantages in the villa.
In November 2010, SONOS entered China, so since 2011, China has the first batch of developers of wifi audio, hoping to imitate the success of SONOS. The earliest batch of developers started development with MTK5350 or Qualcomm's QCA9331, but they all fell on the road of learning. Then Amazon began to intervene and eventually achieved success.
Amazon's Alexa project probably started in 2011, and it should be inspired by iphone4s voice assistant Siri (and also inspired by "Xunfei voice input method". I have to say that Jobs is really a great product manager). As for Echo (Echo tap, Echo, Echo dot) is the most successful product of Alexa's actual application.
