Hojo-ASR-Multi-V1

Overview

Introduction

Hojo‑ASR‑Multi‑V1 is a high‑performance conversational speech recognition model built upon the Qwen3 LLM decoder. It adopts the classic Encoder‑Adapter‑LLM architecture with a customized multi‑frame acoustic fusion structure, making full use of fine‑grained acoustic features and the powerful semantic capabilities of the large language model.

Optimized via multi‑stage modular training and reinforcement learning, the model performs well in complex real‑world scenarios such as noisy conditions, informal pronunciation and oral correction. Building on its recognition capabilities, the model further expands its full‑coverage multilingual recognition capacity, fully supporting major languages including German, French, Spanish, Portuguese, Japanese, Italian, Arabic, Korean and Russian.

Quickstart

Environment Setup

The easiest way to use Hojo-ASR is to install the hojo-asr Python package from PyPI.

conda create -n hojo-asr python=3.10
conda activate hojo-asr

Run the following command to get the minimal installation with transformers-backend support:

pip install -U hojo-asr

Sample Usage

from hojo_asr import HOJO_ASR
parser = argparse.ArgumentParser()
parser.add_argument(
    "--batch_size", type=int, default=10, help="batch size for inference"
)
parser.add_argument("--device", type=str, default="cuda:0")
args = parser.parse_args()
model = HOJO_ASR.load_model("HojoAI/Hojo-ASR-Multi-V1", device=args.device)
# Transcribe
# List of wav paths; for a single scp file pass a str (see dataset.resolve_infer_audio_input)
wav_paths = [
    "/path/to/audio.wav",
]
wav_scp = "test.scp"
with open(wav_paths[0], "rb") as f:
    wav_bytes = f.read()
#LIST OF BYTES
wav_bytes_list = [wav_bytes, wav_bytes]
res = model.run_infer(wav_scp, batch_size=args.batch_size)
# res = model.run_infer(wav_paths, batch_size=args.batch_size)
# res = model.run_infer(wav_bytes_list, batch_size=args.batch_size)
for val in res:
    print("key :", val["key"], " text :", val["text"])
