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

Gemini 3.5 Transcribe represents Google’s most advanced speech-to-text technology to date, tailored for sophisticated voice interactions and immediate transcription. Rather than merely translating speech into text, it converts raw audio into polished, precise, and well-structured text, effectively managing background noise, intricate terminology, various accents, dialects, and natural speech rhythms. Its intelligent transcription capabilities automatically account for self-corrections, eliminate filler words like “ums” and “ahs,” and present the final output in an easily readable format. This model offers continuous bidirectional streaming with sub-second response times, making it ideal for interactive voice applications, alongside the ability to process pre-recorded audio for meetings, call logs, and other recordings while ensuring speaker attribution and word-level timestamps. Additionally, its custom vocabulary feature enables the recognition of specialized terms, unique spellings, postal codes, order IDs, and other industry-specific language, enhancing its versatility for various use cases. As a result, Gemini 3.5 Transcribe stands out as a powerful tool for anyone seeking high-quality transcription services.
