# Meta Patents Technology to Detect Your Mood by Constantly Analyzing Your Tone of Voice

Meta patented AI tech that constantly analyzes your voice and surroundings in order to detect your emotional state. Finally, exactly what we were all asking for: Meta being granted constant access to our offline lives.

As [first caught by Patentlyze](<https://patentlyze.com/patent/meta-ai-tracks-your-emotions-time/>), a patent published on July 2 describes a system that records all the user's "audible communications" and combines it with "contextual factors" like "time of day, location, user activity, or digital interaction." Audio may be "transcribed, and an emotional-state machine learning model may interpret verbal and nonverbal cues to determine emotional indicators."

In other words, the system listens to you and everything you do, combines it with other data, and feeds it all to a mood-predicting AI.

"The system increases the precision and reliability of emotional inference by aligning multimodal sensor inputs on synchronized timelines, which creates a novel data structure that supports richer emotional analysis," reads the patent. "These combined features deliver a technical improvement in automated audio interpretation, enabling continuous emotional monitoring on everyday devices."

According to the patent, the goal of this extraordinarily intrusive system would be to better tailor users' workouts to their emotional state, as "personal trainers cannot provide the level of precision in guidance, such as correcting a pose and/or body movement," as well as Meta's imagined device could.

It's not surprising to see Meta pitch this kind of surveillance technology as a fitness device. Health-tracking wearables have become wildly popular, despite the extraordinary amount of physical data about individual consumers they collect and store.

The key difference in Meta's case, is that rather than crunch biological metrics, it's an AI-powered fly-on-the-wall attempting to measure a person's emotional state by listening in on the world around them, and possibly then connecting that information to all other available data.

"The AI assistant may listen to a user(s) at predefined times to hear various types of communication, such as sighs, laughter, and/or the tone(s) of a voice(s)," reads the patent. "The AI assistant may use these inputs to quantify the user's emotional state or generate other insights about the user."

The patent also discusses connecting audio inputs to information like when a user takes their medicine, proposing that "the AI assistant may take multiple inputs in addition to audio inputs (e.g., of a user's voice) to provide a summary of emotional trends based on various inputs (e.g., a happier emotional state associated with a particular time of day or at a time when medication is taken, etc.)"

It's worth noting that fellow tech giant Amazon tried and failed to market a similar system. In 2020, the company launched the Halo Band, a fitness band with a built-in microphone that was designed to listen in on users and conduct what [Amazon described](<https://www.aboutamazon.com/news/devices/a-new-tool-to-help-you-understand-and-improve-your-social-wellbeing>) as a "tone of voice analysis." Following public backlash in 2021, Amazon [nuked](<https://www.androidcentral.com/halo-view-amazon-privacy-tone>) the microphones when it launched a next-generation version of the band. It [discontinued](<https://www.aboutamazon.com/news/company-news/amazon-halo-discontinued>) the product line altogether in 2023.

Whether we'll ever see Meta attempt to launch a similar mood-tracking device is unclear. In [a statement to *404 Media*](<https://www.404media.co/meta-patents-ai-device-that-tracks-your-emotions-watches-you-take-your-meds/>), a Meta spokesperson said that "like other companies, patents at Meta are often filed to disclose concepts that may or may not be implemented, and a granted patent does not guarantee that Meta has pursued or will pursue the technology described."

The existence of the patent, though, shows that such a device is certainly on Meta's mind — and is yet another [Meta-made product](<https://futurism.com/future-society/backlash-meta-pervert-glasses-afraid>) that stands to strengthen the bridge between our [online and offline](<https://futurism.com/artificial-intelligence/meta-lied-smart-glasses-privacy-class-action-lawsuit>) worlds.

## Author
At Futurism, I've reported extensively on the rise of AI as a cultural and business force shaping the media industry, and more broadly how those dynamics are changing how we all consume and share information and relate to one another. I'm also fascinated by public health policy and ethics, the role of emerging tech in politics and governance — and the powerful people and forces at those intersections — climate change, and the environment. My investigation on Sports Illustrated's use of AI-generated authors with fictional biographies won a 2024 Mirror Award for "Best Story on Media Coverage of Artificial Intelligence in Journalism and the Media" from Syracuse University's SI Newhouse School, I contributed to Niemen Lab's 2025 Predictions for Journalism series, and I've discussed my work for Futurism during appearances on NPR, CNN, the BBC, the CBC, and more. I grew up in rural Pennsylvania and attended the University of Massachusetts Amherst, where I played Division I field hockey for the Minutewomen as a midfielder. Since then, I've lived in New Orleans, Louisiana and Manhattan, New York. I spend my free time running, reading, perusing archival fashion, and searching for the world’s best negroni. I also have a debonair tuxedo cat, Westley, who's named after "The Princess Bride."
