    Speech Recognition: Parakeet CTC 0.6b Spanish English Code Switch Model

    Description

    NVIDIA Parakeet-CTC-0.6B is a 600M parameter model trained on ASR Set with over 28k hours of Spanish (es-US) and English (en-US) speech. The model transcribes speech in Spanish and English, in upper case and lower case alphabets, along with punctuations (period, comma, and question mark), spaces, and apostrophes.

    This model is ready for commercial use.
