Description

Ink 2 represents Cartesia's most advanced and precise streaming speech-to-text model, designed specifically for production voice agents, boasting the lowest word error rate and superior turn detection of any available streaming STT. This model excels in accurately transcribing structured data types like phone numbers, dates, and email addresses on the first attempt, while intuitively recognizing when a speaker begins and ends their speech, eliminating the need for a separate voice activity detection mechanism. Integrated turn detection allows voice agents to respond to events seamlessly, rather than sifting through raw transcript segments. Ink 2 generates a comprehensive array of turn events, providing agents with definitive cues regarding when to listen, interrupt, contemplate, prepare to respond, retract an untimely reply, or engage in conversation. Additionally, the transcript retains a cumulative nature within each turn, ensuring that every update presents the complete text transcribed up to that point rather than just the incremental changes, and the emitted text is considered final the moment it is sent. This innovative design enhances the interaction quality between voice agents and users, making conversations smoother and more effective.

Description

Dessa is an innovative speech-to-speech AI model developed by Block, specifically designed for exploring conversational voice technologies and their various applications. This model uniquely processes audio inputs and generates audio outputs directly, bypassing the need for an intermediary text conversion. Instead of relying on text as a foundation, it has been built from the ground up using actual human conversations, enabling it to facilitate full-duplex communication, where it can listen and speak simultaneously. Designed to operate locally on advanced hardware like the MacBook Pro equipped with an M4 Max chip or superior, Dessa effectively captures nuanced conversational elements such as emotions, sarcasm, laughter, pauses, and turn-taking, which are often diminished in text-based communication systems. Aimed primarily at AI safety researchers and developers, it serves as a powerful tool for examining voice model dynamics, privacy implications, and the intricacies of real-time interactions. Importantly, Dessa is not intended for general business use or as a hosted voice-agent solution, marking its specific role in the realm of research and development within the voice technology landscape. This specificity underscores its potential to deepen understanding of voice interactions and inform future AI advancements.
