About
reazonspeech-nemo-v2 is an automatic speech recognition model trained
on ReazonSpeech v2.0 corpus.
This model supports inference of long-form Japanese audio clips up to several hours.
The model features an improved Conformer architecture from Fast Conformer with Linearly Scalable Attention for Efficient Speech Recognition.
Subword-based RNN-T model. The total parameter count is 619M.
Encoder uses Longformer attention with local context size of 256, and has a single global token.
Decoder has a vocabulary space of 3000 tokens constructed by SentencePiece unigram tokenizer.
We trained this model for 1 million steps using AdamW optimizer following Noam annealing schedule.
We recommend to use this model through our reazonspeech library.
from reazonspeech.nemo.asr import load_model, transcribe, audio_from_path
audio = audio_from_path("speech.wav")
model = load_model()
ret = transcribe(model, audio)
print(ret.text)

How it works
Using it via the API
Once AxForge deploys reazonspeech-nemo for you, it answers on the OpenAI-compatible API — the same base URL and keys as every other model. (reazonspeech-nemo below is illustrative; you get the exact model name on deployment.)
$ curl -sS https://api.axforge.ai/v1/audio/transcriptions \ -H "Authorization: Bearer $AXFORGE_API_KEY" \ -F model="reazonspeech-nemo" -F file=@audio.mp3
