About
Ink 2 is Cartesia’s fastest, most accurate streaming speech-to-text model, built for production voice agents with the lowest word error rate and best turn detection of any streaming STT. It is designed to transcribe structured data such as phone numbers, dates, and emails correctly the first time, while also knowing when a speaker starts and finishes without requiring a separate voice activity detection system. Turn detection is built directly into the model, so voice agents can react to events instead of managing raw transcript segments. Ink 2 emits a full lifecycle of turn events, giving an agent clear signals for when to listen, interrupt, think, prepare a reply, cancel a premature response, or speak. The transcript property is cumulative within a turn, meaning each update contains the full text transcribed so far rather than a delta, and emitted text is final once sent.

About
Neurotechnology AI SDK is a multilingual toolkit for creating speech-to-text and voice processing applications.
It combines a proprietary ASR engine for accurate transcription with a Speaker Diarization engine that separates and labels individual speakers in an audio stream.
Supporting English, Lithuanian, Latvian and Estonian, it delivers fast performance on CPUs and GPUs for real-time or batch processing.
Designed for on-premises use, all audio is processed locally, ensuring full data privacy and control. Its modular architecture lets developers use each component independently or integrate them into stand-alone or client-server systems. Optional speaker recognition through voice biometrics can be added for stronger identity confirmation.
The SDK supports Windows and Linux and provides native libraries for Python, C++, Java and .NET, making it suitable for transcription workflows, analytics platforms or voice-driven applications across a wide range of industries.
