Thousands of languages thrive across the globe, yet modern speech technology -- with all of its benefits -- supports just over a hundred. Computational linguist Kalika Bali dreams of a day when technology acts as a bridge instead of a barrier, working passionately to build new and inclusive systems for the millions who speak low-resource languages. In this perspective-shifting talk, she outlines what happens when a language is omitted from the digital landscape -- and what can be gained when communities keep pace with the future.

Would you pay two percent more for the carbon-neutral version of the products you buy and use every day? In this innovative talk, climate pathfinder Jens Burchardt walks us through the costs and considerations of producing planet-friendly products -- from creation to purchase -- and explains why curbing climate change doesn't have to break the bank. It's an inspiring demonstration of how the barriers to a greener world may not be as insurmountable as we think.

How do you effectively regulate stress? Therapist Esther Perel discusses the importance of creating routines, rituals and boundaries to deal with pandemic-related loss and uncertainty -- both at home and at work -- and offers some practical tools and techniques to help you regain your sense of self.

The "broken" US political system is actually working exactly as designed, says business leader and activist Katherine Gehl.

With candor and cunning, sex historian Kate Lister chronicles the curious journey of an ancient, honest word with innocent origins and a now-scandalous connotation in this uproarious love letter to etymology, queens, cows and all things "cunt." (This talk contains mature language.)

Dictionaries and grammar "rules" don't have the final word on language -- and believing they do can harm more than help, especially for the trans community. Sociolinguist Archie Crowley deconstructs three common myths around language, demonstrating how it's a fluid system that naturally evolves in the direction of inclusion.

Farmers stand at the center of the world, says Andrew Youn, cofounder of One Acre Fund, an agricultural organization that's empowering sub-Saharan farm families with the loans, seeds, fertilizer and training needed to increase crop yields and end hunger. Meet Therese Niyonsaba, a Rwandan farmer who shares how the program helped her family prosper, and learn more about One Acre Fund's goal to lead a farmer-focused green revolution and reach 6.8 million families by 2026. (This ambitious plan is a part of the Audacious Project, TED's initiative to inspire and fund global change.)

From hours-long lines and limited polling locations to confusing and discriminatory registration policies, why is it so hard to vote in the US? Voting rights expert Amber McReynolds offers a proven alternative: a new process, already happening in parts of the country, that could bring accountability, transparency and equity to the outdated and sputtering system that American democracy currently relies on.

The only thing as powerful as our grief is the love we have for those we've lost, says photographer Caroline Catlin.

Biodesigner Natsai Audrey Chieza prototypes the future, imagining a world where people and nature can thrive together. In this wildly imaginative talk, she shares the vision behind her innovation lab, which works at the intersection of nature, technology and society to create sustainable materials and models for the future. Chieza invites us to consider what kind of world we wish for -- and what systemic changes and collaborations need to happen for it to exist.
