High accuracy and optimized performance for transcription in 25 languages
RIVA Parakeet-RNNT-XXL-1.1B ASR Multilingual with Universal Tokenizer (around 1.1B parameters) [1], [2] is trained on ASR Set with over 90,000 hours of speech. Individual tokenizers are trained for each language and then merged into a single tokenizer. The model transcribes 25 languages (English(en-US, en-GB), Spanish (es-US, es-ES), German (de-DE), French (fr-FR, fr-CA), Italian (it-IT), Arabic (ar-AR), Japanese (ja-JP), Korean (ko-KR), Portuguese (pt-BR, pt-PT), Russian (ru-RU), Hindi (hi-IN), Dutch (nl-NL), Danish (da-DK), Norwegian Nynorsk (nn-NO), Norwegian Bokmal (nb-NO), Czech (cs-CZ), Polish (pl-PL), Swedish (sv-SE), Thai (th-TH), Turkish (tr-TR), and Hebrew (he-IL)) in upper case and lower case alphabets along with punctuations, spaces, and apostrophes.
This model is ready for commercial use.
