The music-streaming company Spotify was granted a patent for technology that aims to interpret users’ speech and background noise to better curate the music it serves up.

Why it matters: Aside from being a little weird and invasive, the technology is an example of a future trend in computing: emotion recognition.

What's happening: Music Business Worldwide reported this week that Spotify had filed in February 2018 and been granted this month a patent that uses "speech recognition to determine [users'] 'emotional state, gender, age, or accent' — attributes that can then be used to recommend content."

How it works: According to the patent filing, the company is developing technology that could extract "intonation, stress, rhythm, and the likes of units of speech" that would permit the "emotional state of a speaker to be detected and categorized."

  • Combined with other data from a user's listening history and past requests, appropriate music could then be recommended or played.

What they're saying: Not surprisingly, the internet had fun with this one.

The catch: Technology companies often file patents for innovations that are never used in their products, and a company spokesperson told Pitchfork, "We don't have any news to share at this time."

What's next: Whether or not this capability ever makes it into Spotify, companies are increasingly exploring technology that purports to recognize emotional states through voice tone.

  • Amazon's new Halo fitness tracker analyzes users' vocal tone to evaluate how they're coming off to other people.
  • But there are concerns that emotion recognition could be misused — a report released this week from a U.K. human rights group identified dozens of companies in China using the technology, including some working with the police.

The bottom line: I'm a Spotify user, but the company wouldn't need to read my tone to serve up emotionally appropriate music.

  • Happy? The National. Sad? The National. A bit phlegmy? The National.

The Fed isn't the only problem investors are worried about

The Federal Reserve will be raising rates, just as the economy is slowing. The markets hate that.

Why it matters: The ugly start to the stock trading year doesn't just reflect Fed-induced agita — investors are also worried about a growth slowdown.

The White House said Thursday that a record 14.5 million Americans have signed up for health insurance through Obamacare marketplaces since Nov. 1, including more than 10 million enrollments through HealthCare.gov.

Why it matters: Last year's stimulus bill contained substantial investments in the program, including increased subsidies for people who don't receive health insurance from an employer or through Medicare or Medicaid.

Kremlin says U.S. written responses ignored Russia's main NATO demand

Russian Foreign Minister Sergey Lavrov said Thursday that the United States' written answers to Russia's security demands do not contain a "positive response" to the Kremlin's top priority, which is a freeze on NATO expansion, according to Russian state media.

Why it matters: A spokesperson for the Kremlin stressed that no conclusions will be drawn until Russian President Vladimir Putin has time to analyze the papers, but a lack of movement on Russia's core concerns means the crisis over Ukraine is unlikely to de-escalate.
