'At the beginning of October, Amazon was quietly issued a patent that would allow its virtual assistant Alexa to decipher a user’s physical characteristics and emotional state based on their voice. Characteristics, or “voice features,” like language accent, ethnic origin, emotion, gender, age, and background noise would be immediately extracted and tagged to the user’s data file to help deliver more targeted advertising.
The algorithm would also consider a customer’s physical location — based on their IP address, primary shipping address, and browser settings — to help determine their accent. Should Amazon’s patent become a reality, or if accent detection is already possible, it would introduce questions of surveillance and privacy violations, as well as possible discriminatory advertising, experts said.
The civil rights issues raised by the patent are similar to those around facial recognition, another technology Amazon has used as an anchor of its artificial intelligence strategy, and one that it controversially marketed to law enforcement. Like facial recognition, voice analysis underlines how existing laws and privacy safeguards simply aren’t capable of protecting users from new categories of data collection — or government spying, for that matter. Unlike facial recognition, voice analysis relies not on cameras in public spaces, but microphones inside smart speakers in our homes. It also raises its own thorny issues around advertising that targets or excludes certain groups of people based on derived characteristics like nationality, native language, and so on (the sort of controversy that Facebook has stumbled into again and again).
Why the Government Might Be Interested in Accent Data
If voice-based accent detection can determine a person’s ethnic background, it opens up a new category of information that is incredibly interesting to the government, said Jennifer King, director of consumer privacy at Stanford Law School’s Center for Internet and Society.
“If you’re a company and you’re creating new classifications of data, and the government is interested in them, you’d be naive to think that law enforcement isn’t going to come after it,” she said.
She described a scenario in which knowing a user’s purchase history, existing demographic data, and whether they speak Arabic or Arabic-accented English, Amazon could identify the user as belonging to a religious or ethnic group. King said it’s plausible that the FBI would compel the production of such data from Amazon if it could help determine a user’s membership to a terrorist group. Data demands focused on terrorism are tougher for companies to fight, she said, as opposed to those that are vague or otherwise overbroad, which they have pushed back on.'
