| | | ## Inference |
| | | |
| | |
| | | ##### Define pipeline |
| | | - `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` (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 |
| | | - `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 |
| | | ##### Infer pipeline |
| | | - `audio_in`: the input to decode, which could be: |
| | | - wav_path, `e.g.`: asr_example.wav, |
| | |
| | | ``` |
| | | In this case of `wav.scp` input, `output_dir` must be set to save the output results |
| | | - `audio_fs`: audio sampling rate, only set when audio_in is pcm audio |
| | | - `output_dir`: None (Defalut), the output path of results if set |
| | | - `output_dir`: None (Default), the output path of results if set |
| | | |
| | | ### Inference with multi-thread CPUs or multi GPUs |
| | | FunASR also offer recipes [infer.sh](https://github.com/alibaba-damo-academy/FunASR/blob/main/egs_modelscope/asr/TEMPLATE/infer.sh) to decode with multi-thread CPUs, or multi GPUs. |
| | | FunASR also offer recipes [egs_modelscope/asr/TEMPLATE/infer.sh](https://github.com/alibaba-damo-academy/FunASR/blob/main/egs_modelscope/asr/TEMPLATE/infer.sh) to decode with multi-thread CPUs, or multi GPUs. |
| | | |
| | | - Setting parameters in `infer.sh` |
| | | - `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 |
| | |
| | | - `max_epoch`: number of training epoch |
| | | - `lr`: learning rate |
| | | |
| | | - Training data formats: |
| | | ```sh |
| | | cat ./example_data/text |
| | | BAC009S0002W0122 而 对 楼 市 成 交 抑 制 作 用 最 大 的 限 购 |
| | | BAC009S0002W0123 也 成 为 地 方 政 府 的 眼 中 钉 |
| | | english_example_1 hello world |
| | | english_example_2 go swim 去 游 泳 |
| | | |
| | | cat ./example_data/wav.scp |
| | | BAC009S0002W0122 /mnt/data/wav/train/S0002/BAC009S0002W0122.wav |
| | | BAC009S0002W0123 /mnt/data/wav/train/S0002/BAC009S0002W0123.wav |
| | | english_example_1 /mnt/data/wav/train/S0002/english_example_1.wav |
| | | english_example_2 /mnt/data/wav/train/S0002/english_example_2.wav |
| | | ``` |
| | | |
| | | - Then you can run the pipeline to finetune with: |
| | | ```shell |
| | | python finetune.py |
| | |
| | | ``` |
| | | ## Inference with your finetuned model |
| | | |
| | | - Setting parameters in [infer.sh](https://github.com/alibaba-damo-academy/FunASR/blob/main/egs_modelscope/asr/TEMPLATE/infer.sh) is the same with [docs](https://github.com/alibaba-damo-academy/FunASR/tree/main/egs_modelscope/asr/TEMPLATE#inference-with-multi-thread-cpus-or-multi-gpus) |
| | | - Setting parameters in [egs_modelscope/asr/TEMPLATE/infer.sh](https://github.com/alibaba-damo-academy/FunASR/blob/main/egs_modelscope/asr/TEMPLATE/infer.sh) is the same with [docs](https://github.com/alibaba-damo-academy/FunASR/tree/main/egs_modelscope/asr/TEMPLATE#inference-with-multi-thread-cpus-or-multi-gpus), `model` is the model name from modelscope, which you finetuned. |
| | | |
| | | - Decode with multi GPUs: |
| | | ```shell |
| | |
| | | --njob 64 \ |
| | | --checkpoint_dir "./checkpoint" \ |
| | | --checkpoint_name "valid.cer_ctc.ave.pb" |
| | | ``` |
| | | ``` |
