| | | - `task`: `Tasks.auto_speech_recognition` |
|---|
| | | - `model`: model name in [model zoo](https://alibaba-damo-academy.github.io/FunASR/en/modelscope_models.html#pretrained-models-on-modelscope), or model path in local disk |
|---|
| | | - `ngpu`: `1` (Default), decoding on GPU. If ngpu=0, decoding on CPU |
|---|
| | | - `ncpu`: `1` (Default), sets the number of threads used for intraop parallelism on CPU |
|---|
| | | - `output_dir`: `None` (Default), the output path of results if set |
|---|
| | | - `batch_size`: `1` (Default), batch size when decoding |

| | | - `audio_in`: the input to decode, which could be: |
|---|
| | | - wav_path, `e.g.`: asr_example.wav, |
|---|
| | | - pcm_path, `e.g.`: asr_example.pcm, |
