一、选择系统

这个镜像可以

1.1 更新环境

python -m pip install --upgrade pip

二、安装使用whisper

2.1 创建环境

# ssh登录系统
# 切换到root用户
mkdir /opt/tools/
cd /opt/tools/
# 安装miniconda
wget https://repo.anaconda.com/miniconda/Miniconda3-latest-Linux-x86_64.sh
chmod +x Miniconda3-latest-Linux-x86_64.sh
./Miniconda3-latest-Linux-x86_64.sh
#按提示操作，安装目录建议选择/opt/miniconda3
#创建软链接
ln -s /opt/miniconda3/bin/conda /usr/local/bin/conda
#退出shell重新登陆，然后后续操作
#创建环境
conda create -n whisper python=3.9
conda activate whisper

2.1 安装

2.1.1安装基础包

pip install -U openai-whisper
或者
pip install git+https://github.com/openai/whisper.git
或者
pip install -i https://pypi.tuna.tsinghua.edu.cn/simple openai-whisper

2.1.2安装依赖

pip install tiktoken
pip install setuptools-rust
#在conda whisper环境外执行，安装ffmpeg
sudo apt update && sudo apt install ffmpeg

3测试1

whisper audio.mp3 --model medium --language Chinese

代码调用

import whisper
import arrow

# 定义模型、音频地址、录音开始时间
def excute(model_name,file_path,start_time):
    model = whisper.load_model(model_name)
    result = model.transcribe(file_path)
    for segment in result["segments"]:
        now = arrow.get(start_time)
        start = now.shift(seconds=segment["start"]).format("YYYY-MM-DD HH:mm:ss")
        end = now.shift(seconds=segment["end"]).format("YYYY-MM-DD HH:mm:ss")
        print("【"+start+"->" +end+"】："+segment["text"])

if __name__ == '__main__':
    excute("base","1001.mp3","2022-10-24 16:23:00")

3测试2 语着分离

创建代码

import os
import whisper
from pyannote.audio import Pipeline
from pyannote_whisper.utils import diarize_text
import concurrent.futures

pipeline = Pipeline.from_pretrained("pyannote/speaker-diarization", use_auth_token="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")
output_dir = '/root/autodl-tmp/pyannote-whisper'

def process_audio(file_path):
    model = whisper.load_model("large")
    asr_result = model.transcribe(file_path, initial_prompt="语音转换")
    diarization_result = pipeline(file_path)
    final_result = diarize_text(asr_result, diarization_result)

    output_file = os.path.join(output_dir, os.path.basename(file_path)[:-4] + '.txt')
    with open(output_file, 'w') as f:
        for seg, spk, sent in final_result:
            line = f'{seg.start:.2f} {seg.end:.2f} {spk} {sent}\n'
            f.write(line)

if not os.path.exists(output_dir):
    os.makedirs(output_dir)

wave_dir = '/root/autodl-tmp/pyannote-whisper'
# 获取当前目录下所有wav文件名
wav_files = [os.path.join(wave_dir, file) for file in os.listdir(wave_dir) if file.endswith('.wav')]


# 处理每个wav文件
with concurrent.futures.ThreadPoolExecutor(max_workers=3) as executor:
    executor.map(process_audio, wav_files)

print('处理完成！')

报错ModuleNotFoundError: No module named 'pyannote'

解决方案

pip install  pyannote.audio

报错No module named 'pyannote_whisper'

如果你使用使用AutoDL平台，你可以使用学术代理加速

source /etc/network_turbo

git clone https://github.com/yinruiqing/pyannote-whisper.git

在项目里面写代码就可以了,或者复制代码里面的pyannote_whisper.utils模块代码

三、安装使用funASR

1 安装

官网

1.1 安装 Conda（可选）

wget https://repo.continuum.io/miniconda/Miniconda3-latest-Linux-x86_64.sh
sh Miniconda3-latest-Linux-x86_64.sh
source ~/.bashrc
conda create -n funasr python=3.8
conda activate funasr

1.2 安装 Pytorch（版本 >= 1.11.0）

pip3 install torch torchaudio

如果您的环境中存在CUDA，您应该安装与CUDA匹配的版本的pytorch。匹配列表可以在docs中找到。

1.3 安装funASR

从 pip 安装

pip3 install -U funasr
# 对于中国的用户，您可以使用以下命令进行安装：
# pip3 install -U funasr -i https://mirror.sjtu.edu.cn/pypi/web/simple

或者从源码安装funASR

git clone https://github.com/alibaba/FunASR.git && cd FunASR
pip3 install -e ./

1.4 安装 modelscope（可选）

如果您想使用 ModelScope 中的预训练模型，您应该安装 modelscope：

pip3 install -U modelscope
# 对于中国的用户，您可以使用以下命令进行安装：
# pip3 install -U modelscope -i https://mirror.sjtu.edu.cn/pypi/web/simple

1.5 如何从本地模型路径推断（可选）

通过 modelscope-sdk 将模型下载到本地目录

from modelscope.hub.snapshot_download import snapshot_download

local_dir_root = "./models_from_modelscope"
model_dir = snapshot_download('damo/speech_paraformer-large_asr_nat-zh-cn-16k-common-vocab8404-pytorch', cache_dir=local_dir_root)

或者通过 git lfs 将模型下载到本地目录

git lfs install
# git clone https://www.modelscope.cn/<namespace>/<model-name>.git
git clone https://www.modelscope.cn/damo/speech_paraformer-large_asr_nat-zh-cn-16k-common-vocab8404-pytorch.git

使用本地模型路径进行推断

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

2 使用funASR

2.1 使用funASR

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

inference_pipeline = pipeline(
    task=Tasks.auto_speech_recognition,
    model='damo/speech_paraformer-large-vad-punc_asr_nat-zh-cn-16k-common-vocab8404-pytorch',
    model_revision="v1.2.4")

rec_result = inference_pipeline(audio_in='1001.wav')

print(rec_result['sentences'])

with open('result.txt', 'w', encoding='utf-8') as f:
    print(rec_result, file=f)

print(rec_result)

2.2 使用 pyannote.audio 进行语者分离

第一步：安装依赖

pip install pyannote.audio

第二步：创建key

https://huggingface.co/settings/tokens

第三步：测试pyannote.audio

from pyannote.audio import Pipeline
pipeline = Pipeline.from_pretrained("pyannote/speaker-diarization", use_auth_token="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")

# send pipeline to GPU (when available)
import torch
pipeline.to(torch.device("cuda"))

# apply pretrained pipeline
diarization = pipeline("1002.wav")
print(diarization)
# print the result
for turn, _, speaker in diarization.itertracks(yield_label=True):
    print(f"start={turn.start:.1f}s stop={turn.end:.1f}s speaker_{speaker}")
# start=0.2s stop=1.5s speaker_0
# start=1.8s stop=3.9s speaker_1
# start=4.2s stop=5.7s speaker_0
# ...

            line = f'{seg.start:.2f} {seg.end:.2f} {spk} {sentence}\n'
            fp.write(line)
