Baidu’s AI-enabled consumer hardware arm Xiaodu Technology has secured an undisclosed amount in a B round, at a valuation of $5.1 billion. An Alexa counterpart, Xiaodu’s AI voice assistant has been applied in a variety of smart speakers, smartphones, smartwatches, cars, and robots developed by Baidu and its partners. Incomes from services including membership to advertising surpassed 10% of Xiaodu revenues in the most recent quarter, supplementing revenue from hardware, according to Herman Yu, chief strategy officer and chief financial officer of Baidu.
