About DessaVoice
DessaVoice is an independent platform showcasing Block's Dessa voice AI model. It provides free access to six official Dessa recordings demonstrating full-duplex speech capabilities, a Mac M4 Max readiness checker to assess local deployment compatibility, and a live voice playground for interactive conversation practice. The site also offers paid live voice calls through hosted real-time voice AI or bring-your-own-key mode with OpenAI credentials.
DessaVoice is not affiliated with Block, Inc. and does not distribute Dessa's model weights. Block's official Dessa model remains available only through a research preview waitlist at block.xyz/dessa. The platform serves as an independent information hub and practice tool, clearly disclaiming any connection to Block while providing detailed technical comparisons with competing voice models like Sesame AI, OpenAI GPT-Live-1, and Kyutai Moshi.

FAQ
- Can I run Dessa AI locally on my MacBook Pro?
- Block says Dessa's inference runs faster than real time and runs locally on a MacBook Pro M4 Max or better. However, Block has not publicly released Dessa's model weights yet, so you cannot download and run it. DessaVoice provides a free hardware checker to show how your Mac compares.
- Is DessaVoice affiliated with Block, Inc.?
- No. DessaVoice is an independent website not affiliated with Block, Inc. The official Dessa page is block.xyz/dessa. DessaVoice is an independent voice AI practice studio and information hub.
- How does Dessa AI compare to Sesame AI?
- Dessa was trained only on human conversation audio with no text and no pretrained models, and is full-duplex with natural backchannels. Sesame's Conversational Speech Model is a text-and-speech model with a Llama backbone trained on about one million hours of audio. Sesame has open-sourced a checkpoint under Apache 2.0, while Dessa is waitlist-only.
- What is Dessa AI by Block?
- Dessa is a full-duplex speech model from a small AI research lab at Block, released as a research preview. Block says it was trained from scratch on nothing but human conversation, with no text and no pretrained models. It takes audio in and gives audio out, listens and talks at the same time, and knows when to cut in or backchannel with a “yeah!” or “got it!”.
- Is Dessa Voice AI free to try online?
- Block's official Dessa model is a research preview that is only available through a waitlist at block.xyz/dessa. On DessaVoice, the breakdown of Block's official recordings, the MacBook hardware readiness checker and bring-your-own-key (BYOK) mode with your own OpenAI key are free. Live hosted voice calls require the $4.90 Instant Voice Pass. Our live engine is a real-time interruptible voice AI, not Block's Dessa model.
