## Dessa AI voice model
Dessa is a new artificial intelligence model from Jack Dorsey's Block that mimics human speech convincingly.
## Robotic voice safety feature
Robotic voices were a safety feature to indicate nobody was present, but Dessa removes this tell.
## Dessa's training method
Dessa was trained only on recorded human conversation to capture every sigh, giggle, and stumble.
## Creative industry benefits
Dessa reduces costs for creative industries to generate more realistic AI productions.
## Scam risks increase
Scammers can now use Dessa to make calls that sound like trusted contacts, increasing fraud targets.

## Marco Rubio impersonation
An impostor used Dessa to mimic Marco Rubio's voice for foreign ministers and a member of Congress.
## Joe Biden robocall
Two days before the 2024 New Hampshire primary, an AI imitation of Joe Biden cost $150 to make.
## Dessa's safety concerns
Dessa's team acknowledges risks and wants outside researchers to help address them.

> A model that learned to talk from sound alone is new territory, and we want outside eyes on it
## Key takeaway

Dessa AI voice model, trained on human conversation, mimics speech so convincingly it removes traditional robotic voice safety features but increases scam risks.
