Block's Dessa improves conversations but does not solve checkout problems

AI-assisted source summary · not independently verified. Content standards

Block released the speech-to-speech AI model Dessa, which can listen and respond simultaneously, but it has not yet solved the problems of identifying the payer by voice or authorizing payments by voice. Square Kiosk can process English-language voice orders based on the menu, prices and modifiers in a merchant's Square account, but is available only in the US; payment is still completed via tap, dip or PIN on the built-in card reader.
