前几天，又一款非自回归的文字转语音的AI模型：MaskGCT，开放了源码，和同样非自回归的F5-TTS模型一样，MaskGCT模型也是基于10万小时数据集Emilia训练而来的，精通中英日韩法德6种语言的跨语种合成。数据集Emilia是全球最大且最为多样的高质量多语种语音数据集之一。
本次分享一下如何在本地部署MaskGCT项目，让您的显卡再次发烧。
首先确保本地已经安装好Python3.11环境，安装包可以去Python的官方下载:
python.org
随后克隆官方项目:
git clone https://github.com/open-mmlab/Amphion.git
官方提供了基于linux的安装shell脚本：
pip install setuptools ruamel.yaml tqdm
pip install tensorboard tensorboardX torch==2.0.1
pip install transformers===4.41.1
pip install -U encodec
pip install black==24.1.1
pip install oss2
sudo apt-get install espeak-ng
pip install phonemizer
pip install g2p_en
pip install accelerate==0.31.0
pip install funasr zhconv zhon modelscope
# pip install git+https://github.com/lhotse-speech/lhotse
pip install timm
pip install jieba cn2an
pip install unidecode
pip install -U cos-python-sdk-v5
pip install pypinyin
pip install jiwer
pip install omegaconf
pip install pyworld
pip install py3langid==0.2.2 LangSegment
pip install onnxruntime
pip install pyopenjtalk
pip install pykakasi
pip install -U openai-whisper
这里笔者为大家转换为适合Windows的requirements.txt依赖文件：
setuptools
ruamel.yaml
tqdm
transformers===4.41.1
encodec
black==24.1.1
oss2
phonemizer
g2p_en
accelerate==0.31.0
funasr
zhconv
zhon
modelscope
timm
jieba
cn2an
unidecode
cos-python-sdk-v5
pypinyin
jiwer
omegaconf
pyworld
py3langid==0.2.2
LangSegment
onnxruntime
pyopenjtalk
pykakasi
openai-whisper
json5
运行命令：
pip3 install -r requirements.txt
安装依赖即可。
安装onnxruntime-gpu:
pip3 install onnxruntime-gpu
安装torch三件套:
pip3 install torch torchvision torchaudio --index-url https://download.pytorch.org/whl/cu118
由于MaskGCT项目后端依赖espeak软件，所以需要在本地进行配置，eSpeak 是一个紧凑的开源文本转语音 (TTS) 合成器，支持多种语言和口音 。它使用“共振峰合成”方法，允许以较小的体积提供多种语言 。语音清晰，可以高速使用，但不如基于人类语音录音的较大合成器自然流畅，而MaskGCT就是在espeak的合成基础上进行二次推理。
首先运行命令安装espeak:
winget install espeak
如果装不上，也可以下载安装包手动安装：
https://sourceforge.net/projects/espeak/files/espeak/espeak-1.48/setup_espeak-1.48.04.exe/download
随后下载espeak-ng安装包：
https://github.com/espeak-ng/espeak-ng/releases
下载后双击安装。
接着把 C:\Program Files\eSpeak NG\libespeak-ng.dll 拷贝到 C:\Program Files (x86)\eSpeak\command_line 目录。
然后把 libespeak-ng.dll 重命名为 espeak-ng.dll
最后把 C:\Program Files (x86)\eSpeak\command_line 目录配置到环境变量即可。
都配置好之后，编写推理脚本 local_test.py:

首次推理会在hf_download目录下载10个G的模型。
推理过程中，会占用11G的显存：
如果您的显存低于11G，那么务必打开Nvidia控制面板的系统内存回退策略，通过系统内存来补足显存：
如果愿意，也可以基于gradio写一个简单的webui界面，app.py:
import os
import gc
import re
import gradio as gr
import numpy as np
import subprocess
os.environ['HF_HOME'] = os.path.join(os.path.dirname(__file__), 'hf_download')
# 设置HF_ENDPOINT环境变量

reference_wavs.append(name)
def change_choices():
reference_wavs = ["请选择参考音频或者自己上传"]
for name in os.listdir("./参考音频/"):
reference_wavs.append(name)
return {"choices":reference_wavs, "__type__": "update"}
def change_wav(audio_path):
text = audio_path.replace(".wav","").replace(".mp3","").replace(".WAV","")
# text = replace_speaker(text)
return f"./参考音频/{audio_path}",text
def do_cloth(gen_text_input,ref_audio_input,model_choice_text,model_choice_re,ref_text_input):

res.wait()
return "output.wav"

当然，别忘了安装gradio依赖:
pip3 install -U gradio
运行效果是这样的：
MaskGCT模型的优势在于语气韵律层面十分突出，可以媲美真实语音，缺点也很明显，运行成本偏高，工程化层面优化不足。MaskGCT项目主页中已经有其商业版本模型的入口，据此推断，官方应该不会在开源版本中太过发力，最后奉上一键整合包，与众乡亲同飨:
