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

Phonic-1 is a real-time speech-to-speech AI model offered through Phonic’s voice-agent development platform. It processes spoken input and generates spoken responses, supporting streaming conversations, configurable voices, turn-taking, and interruption handling. Developers can access the model through an API and SDKs, then use Phonic’s hosted tools to build, test, and deploy conversational voice agents. The platform is designed for developers and businesses creating voice applications for customer support, sales, appointment handling, and other spoken interactions. It includes options for hosted or self-managed deployment and provides documented integrations and webhook-based connections to external services. Phonic states that its voice technology supports more than 50 languages.
