This tutorial uses a single RTX 4090 computing resource, and the model only supports English speech recognition.
Parakeet-tdt-0.6b-v2 is a 600 million parameter high-performance automatic speech recognition (ASR) model open-sourced by NVIDIA in May 2025. It is the latest version of the Parakeet series. The model is based on the FastConformer encoder architecture and the TDT decoder, and can efficiently transcribe up to 24 minutes of English audio clips at a time. The model focuses on high-precision, low-latency English speech transcription tasks and is suitable for real-time English speech-to-text scenarios (such as customer service conversations, meeting records, voice assistants, etc.). The related paper results are "Fast Conformer with Linearly Scalable Attention for Efficient Speech Recognition".
