(Reuters) -- Amazon.com Inc is dominating the nascent market for voice-controlled speakers, research firm eMarketer said on Monday.
The e-commerce giant's Amazon Echo and Echo Dot devices will claim a 70.6 percent share of the U.S. market this year, the study found. The speakers feature Alexa, Amazon's voice-controlled aide, which users can tell to play music, order an Uber or turn on the house lights.
The number of active U.S. users will more than double for the devices this year, to 35.6 million, eMarketer said.
The report underscores Amazon's progress in making Alexa and its speech-recognition technology an integral part of customers' lives. More users means more data that can improve Alexa's understanding and could make it a top platform for voice, like Windows is for desktop.
Google's share is expected to grow, though. Tests by analysts have shown the technology underpinning the Google Home to match or be superior to competitors. A survey by Mahaney found the device's brand awareness in the United States already equaled 80 percent of Alexa's, despite being on the market for fewer months.
The statistics from eMarketer focused on speakers and left out other virtual assistants: notably, Apple Inc's Siri and Microsoft Corp's Cortana. More than 60 million in the United States will use virtual assistants at least once monthly in 2017, the report said. That's over a quarter of U.S. smartphone users.
