Block Introduces Dessa, A Voice AI Model For More Natural Conversations

Block has introduced Dessa, a speech AI model designed to make conversations with AI sound more natural by capturing emotion, pauses and human speech patterns. It can listen and respond simultaneously and is designed to run locally on consumer hardware.

According to Block’s research team, Dessa was trained entirely on human speech using a single NVIDIA GPU rack. Unlike conventional systems that convert speech into text before generating a response, it processes spoken interactions directly.

Real-Time Speech And Emotional Expression

Dessa uses a full-duplex architecture, allowing it to listen and speak at the same time rather than waiting for a person to finish. Block says this approach helps preserve vocal cues that can be lost when speech is converted into text.

The company also says Dessa draws knowledge from conversational data within the model itself, rather than relying on a separate large language model. Its full capabilities and limitations have not yet been disclosed.

“We believe voice is the most natural way to interact with intelligence,” Block CEO Jack Dorsey wrote in a post announcing Dessa, highlighting its ability to convey emotion, nuance and natural cadence.

Demonstrations shared by Block researchers show the model adapting its tone to different situations. However, these examples do not yet establish how consistently it can interpret emotion in real-world conversations.

Local Processing And Safety

Block says Dessa can run on consumer hardware, including a MacBook with an M4 Max chip or better. Local processing could reduce latency, cloud computing costs and reliance on external infrastructure.

The model is not yet publicly available. Block has invited safety researchers to test scenarios in which a convincing AI voice could mislead someone into believing they are speaking with a human.

Potential Applications

Block’s ecosystem includes products for consumers and small businesses, creating potential applications in commerce and customer service. Its Square platform already supports AI-powered voice ordering.

Dessa could eventually support additional voice-enabled services while reducing reliance on cloud processing. However, its commercial potential will depend on reliability, safety and performance on everyday devices.

Dictionary.com Names ‘Maxxing’ Its Word Of The Year For 2026

Dictionary.com has named “maxxing” its Word of the Year for 2026, reflecting a growing online trend of optimising almost every aspect of life, from health and appearance to work and leisure.

The choice follows last year’s selection of “6-7”, a phrase popularised by younger internet users. Unlike that expression, “maxxing” has spread beyond niche online communities into everyday social media language.

From “Looksmaxxing” To Mainstream Usage

Derived from “maximising”, “maxxing” describes doing something to the fullest or optimising it as much as possible. According to Dictionary.com, its roots lie in phrases such as “maxing out” a credit card and gaming terminology.

During the 2010s, the term gained traction in manosphere and incel communities through “looksmaxxing”, referring to efforts to improve physical attractiveness through fitness, grooming and, in some cases, more extreme measures.

The word later became associated with controversial manosphere influencers, including livestreamer Braden Peters, known as Clavicular, who promotes an intense focus on male appearance.

A Broader Meaning

Younger social media users have since expanded “maxxing” beyond its original associations. Searches for the term surged in August as it became a label for everything from wellness routines to workplace habits. It is also used ironically to poke fun at the pressure to constantly improve.

“Maxxing is the linguistic manifestation of a culture increasingly preoccupied with getting the most out of everything,” said Steve Johnson, director of lexicography for Dictionary Media Group at IXL Learning.

Johnson noted that the term can signal enthusiasm for self-improvement, exaggerate it for humour or reject the idea of constant optimisation altogether. Examples include “proteinmaxxing” at breakfast, “tokenmaxxing” with AI tools at work and “cozymaxxing” on a Friday night.

The Many Forms Of “Maxxing”

The term has generated numerous variations. “Softmaxxing” refers to relatively modest appearance improvements, such as a new haircut, while “hardmaxxing” describes more extreme approaches, including severe dieting or cosmetic procedures. “Jestermaxxing” involves using humour to gain social acceptance or online attention, while “sleepmaxxing” focuses on improving sleep quality or duration.

These variations show how the language of optimisation has spread across personal identity, health, social status and leisure.

The Pressure To Do More

The popularity of “maxxing” also reflects a wider tension between self-improvement and the expectation to make every activity more productive. In the workplace, “tokenmaxxing” describes employees being encouraged to use AI tools as much as possible, turning technological adoption into another measure of performance.

The term captures a culture in which ordinary activities can become opportunities for measurable gains, even as some people use the language to question that pressure.

Other Words On The Shortlist

Other candidates for Dictionary.com’s 2026 Word of the Year included “affordability”, “data center”, “odyssey” and “unc”.

Interest in “odyssey” may have been boosted by Christopher Nolan’s film The Odyssey, while “unc”, short for “uncle”, is used by Gen Z and Gen Alpha to describe someone older who is perceived as out of touch or uncool.

“Maxxing” ultimately stands out for capturing a defining online impulse: to optimise everyday life, share the process and keep striving for more.
