A Reddit user shared Block's Dessa AI voice model, calling it "absolutely crazy." A demo screenshot shows Dessa's generated speech waveform side-by-side with a human recording, automatically tagging paralinguistic events like laughs, "blown away" moments, and speaking louder — indicating fine-grained capture of tone and emotion. Full details are in Block's blog at block.xyz/dessa.
