    Model Overview

    RIVA Parakeet-CTC-0.6B-Unified ASR Vietnamese (around 600M parameters) [1] is trained on an ASR dataset with over 4,000 hours of Vietnamese (vi) speech. The model transcribes speech in Vietnamese, in upper case and lower case alphabets, along with punctuations (period, comma, and question mark), and spaces.

    This model is ready for commercial/non-commercial use.
