Meanwhile, Amazon learns how popular Alexa may be among its own employees.
In a pilot program launched earlier this year, Amazon saw that more than half of the meetings – 53 percent to be exact – start talking to Alexa Voice Assistant, instead of manually entering the caller information on the existing touch panel, according to Internal data obtained by CNBC.
In addition, meetings have started in less than nine seconds on average, showing the data.  The results, which come from June, are based on a pilot program that installed Alexa for Business in 698 conference rooms on 5 different Amazon buildings in Seattle. The program is run by AWS Product Adoptions, a team that tests AWS products internally before distributing more.
The rapid adoption of Alexa for Business among Amazon employees shows the great potential of speech technology in the workplace.
But Amazon could also bring that type of wider adoption externally if they were to aggressively promote and clarify Alexa for business positioning as a business tool, as many businesses are still unaware of Alexa's abilities at work, according to Joe Kleinschmidt, CEO of Obindo, another early partner for the Alexa for Business program.
For example, Kleinschmidt said his clients tend to ask much more about Obindo's integration with tools like email and messaging apps in relation to Alexa skills. Obindo, a software that transfers company information, who is responsible for individual projects with a simple command, works with simple spoken questions on Alexa. But when Kleinschmidt shows this feature to customers, it's common: "We did not even think of using Alexa in the office," he said.
Kleinschmidt said that it would help raise awareness of Alexa's potential in the business area if Amazon ran stronger marketing campaigns around Alexa for Business, and noted how most ads about Alexa are focused on user things for use.
"The eyes of the people only light when we show them how to use Obindo inside Alexa," he said. "I would like to see Amazon tell more about those stories that really capture people's imagination."
An Amazon employee, who agreed to talk to CNBC on condition that he was not named because he was not authorized to talk about the issue, said Alexa for Business is a handy tool for starting meetings, which reduces the time to call all participants. But he also noted that the use is still limited to basic functions, such as starting meetings or dimming the room lights.
Kleinschmidt, at Obindo, said that the rapid adoption at the most basic level to start meetings with voice is expected. However, according to Alexa's sophistication and ability to offer much more intelligent data, Amazon would "leave a lot on the table" if it no longer promotes its ability, he said.
"This platform is about so much more than making meetings run a little more efficiently," he says.
