Qwen3 ASR model for fasr
Project description
fasr-asr-qwen3
内置 Qwen3-ASR 推理(Transformers / vLLM)的语音识别模型插件,为 fasr 提供无时间戳 ASR 能力。
安装
pip install fasr-asr-qwen3
注册模型
| 注册名 | 类 | 默认 checkpoint | 说明 |
|---|---|---|---|
qwen3_0.6b |
Qwen3_06BForASR |
Qwen/Qwen3-ASR-0.6B |
Qwen3 小模型,当前不返回时间戳 |
qwen3_1.7b |
Qwen3_17BForASR |
Qwen/Qwen3-ASR-1.7B |
Qwen3 大模型,当前不返回时间戳 |
使用方式
from fasr import AudioPipeline
pipeline = (
AudioPipeline()
.add_pipe("detector", model="fsmn")
.add_pipe("recognizer", model="qwen3_1.7b") # 或 qwen3_0.6b
.add_pipe("sentencizer", model="ct_transformer")
)
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
model = registry.asr_models.get("qwen3_1.7b")(gpu_memory_utilization=0.6)
# or model.load_checkpoint("/path/to/custom/qwen3")
运行期 / 会话参数
| 参数 | 类型 | 默认值 | 说明 |
|---|---|---|---|
checkpoint |
str | None |
子类各自默认 | 远程 repo_id;非空时实例化会自动下载到 cache_dir |
cache_dir |
str | Path | None |
None |
缓存目录,None 使用 fasr.utils.get_cache_dir() |

输出说明
- 当前模型不返回词级/字级时间戳。
- fasr 中会把整段识别文本作为一个
AudioToken返回。
