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

Sonic is an advanced text-to-speech model designed specifically for real-time voice agents, featuring a natural delivery system with a response time of less than 90 milliseconds and supporting over 40 languages seamlessly. Its primary aim is to facilitate effortless voice interactions, characterized by a tone that adapts to various contexts, a steady pacing, and speech that aligns with the natural flow of conversation. Sonic automatically interprets the emotional nuances within transcripts, adjusting its delivery accordingly, and allows for the direct insertion of non-verbal cues like laughter into the spoken text. Faithful to the original transcripts, the model generates clear audio across different languages and voice options while effortlessly managing alphanumeric data, including order and phone numbers, email addresses, and IDs, without requiring any prior processing. Its context-aware pronunciation ensures that heteronyms are articulated correctly based on surrounding terms, and customizable pronunciation dictionaries empower teams to dictate how specific proper nouns and industry-related terminology should be pronounced. This comprehensive approach not only enhances the quality of interactions but also tailors the user experience to meet diverse communication needs.
