Inference

Quick start

Paraformer model

from modelscope.pipelines import pipeline
from modelscope.utils.constant import Tasks

inference_pipeline = pipeline(
    task=Tasks.auto_speech_recognition,
    model='damo/speech_paraformer-large_asr_nat-zh-cn-16k-common-vocab8404-pytorch',
)

rec_result = inference_pipeline(audio_in='https://isv-data.oss-cn-hangzhou.aliyuncs.com/ics/MaaS/ASR/test_audio/asr_example_zh.wav')
print(rec_result)

API-docs

define pipeline

• task: Tasks.auto_speech_recognition
• model: model name in model zoo, or model path in local disk
• ngpu: 1 (Defalut), decoding on GPU. If ngpu=0, decoding on CPU
• ncpu: 1 (Defalut), sets the number of threads used for intraop parallelism on CPU
• output_dir: None (Defalut), the output path of results if set
• batch_size: 1 (Defalut), batch size when decoding

infer pipeline

• audio_in: the input to decode, which could be:
  • wav_path, e.g.: asr_example.wav,
  • pcm_path,
  • audio bytes stream
  • audio sample point
  • wav.scp
