FireRedLID language identification model for fasr

Project description

fasr-lid-firered

基于 FireRedLID 的语种识别模型插件,为 fasr 提供音频语种自动识别能力。

安装

pip install fasr-lid-firered

注册模型

注册名 默认 checkpoint 说明
firered FireRedForLID xukaituo/FireRedLID 语种识别,返回语言标识(如 "zh""en"

模型权重默认从 ModelScope 自动下载。

使用方式

单独使用模型

模型实例化时会自动执行 download_checkpoint() + load_checkpoint()

from fasr.config import registry
from fasr.data import Waveform

model = registry.lid_models.get("firered")(use_gpu=True, use_half=True)

waveform = Waveform.from_file("example.wav")
lang = model.identify(waveform)
print(lang)  # e.g. "zh"

# 使用自定义权重目录
model.load_checkpoint("/path/to/custom/firered-lid")

运行期 / 会话参数

参数 类型 默认值 说明
checkpoint str | None "FireRedTeam/FireRedLID" 远程 repo_id;非空时实例化会自动下载
cache_dir str | Path | None None 缓存目录,None 使用 fasr.utils.get_cache_dir()
endpoint Literal["modelscope", "huggingface", "hf-mirror"] "modelscope" 下载端点
use_gpu bool True 是否使用 GPU 推理
use_half bool False 是否使用 FP16 推理加速
max_chunk_seconds float 60.0 单次推理最大音频时长;更长音频会被自动切块
