Two moves show voice AI moving onto local hardware as states begin policing synthetic advertising.

🤖 Block trains a speech-only AI model

Decoded: Block (XYZ) built Dessa from scratch using only human conversation, The Verge reported on Oct. 23. The company says the speech-to-speech model can run locally on a MacBook Pro M4 Max or better and will initially go to a small group of AI-safety researchers.

Why it matters: Dessa tests whether voice systems can preserve timing and emotion without converting every exchange into text. For Block, local inference offers a path to AI features with lower cloud dependence, though the limited research release means commercial impact is not yet established.

🏛️ Pennsylvania requires labels on AI-generated ads

Decoded: Governor Josh Shapiro signed the Artificial Intelligence Deceptive Advertising Act, requiring still-image, video, audio and text ads that are significantly modified or generated by AI to carry a disclosure in the same format, The Verge reported on Oct. 24. The law applies to ads shown in Pennsylvania regardless of where they were created.

Why it matters: The law turns synthetic-media labeling from platform policy into a compliance obligation. Broad exemptions and undefined terms such as significantly modified leave enforcement uncertainty for advertisers and ad-tech platforms.
