About

Dessa is Block's speech-to-speech artificial intelligence model for conversational voice research and applications. It takes audio input and produces audio output directly, without converting speech into text as an intermediate step. Trained from scratch on human conversation rather than text, the model supports full-duplex interaction, listening and speaking at the same time, and runs locally on a MacBook Pro with an M4 Max chip or better. It captures conversational cues such as emotion, sarcasm, laughter, pauses, and turn-taking that can be lost in text-based pipelines. Dessa is intended for AI safety researchers and developers studying voice-model behavior, privacy, and real-time interaction. It is a speech model for research and development, not a general-purpose business application or hosted voice-agent platform.

About

KugelAudio is the most realistic speech AI platform, combining text-to-speech, speech-to-text, and voice-to-voice in one stack. With 39-50ms inference latency (lowest on the market), 30-second voice cloning, on-premises deployment, and industry-leading accuracy on email addresses, IBANs, and phone numbers, it's built for production voice applications where quality and compliance matter. It's a strong fit for voice bots and conversational agents that need to handle structured data without misreads, real-time applications requiring sub-50ms latency, and regulated industries like banking, insurance, healthcare, and the public sector that need on-premises or EU-sovereign deployment. Beyond enterprise voice automation, KugelAudio also powers branded voice experiences through natural cloning from 30 seconds of audio, multilingual products across over 30 languages German, English, French, and Italian, and media or content production needing the most realistic synthetic voices available.

Audience

AI safety researchers and developers evaluating or building speech-based conversational AI.

Audience

KugelAudio is for teams shipping production voice applications where quality, latency, and compliance are non-negotiable, from conversational AI and contact-center platforms to banks, insurers, healthcare, and public-sector deployments with strict GDPR or on-premises requirements. It's equally suited to media, audiobook, e-learning, gaming, and accessibility teams that need realistic multilingual speech, fast voice cloning, and the freedom to host on managed API, EU-sovereign cloud, or fully air-gapped infrastructure.
