自己搭建[文本转语音]服务器

一、简介

准备用基于esp8266的nodemcu开发板做一个天气时钟。

一步一步记录代码编写过程。

竹壳天气时钟

Bamboo shell weather clock

使用基于esp8266的NodeMCU制作。

计划用竹子做最后成品的外壳，所以才有了这个名称。

上一篇文章已经完成了时钟和天气的显示，下一步要做语音控制报时和报天气，今天记录一下我使用三丰云免费云服务器搭建TTS的过程。三丰云 https://www.sanfengyun.com 我已经用了一段时间，感觉还是很不错的，运行也很稳定。

二、TTS服务器搭建

在云服务器上安装Ubuntu Linux，安装docker-ce docker-ce-cli

然后添加docker代理,复制后粘贴到shell终端即可

bash 复制代码

sudo tee /etc/docker/daemon.json <<-"EOF"
{
    "registry-mirrors": ["https://dockerpull.com"]
}
EOF

然后建立一个tts文件夹并进入，以下代码复制后粘贴到shell终端即可

bash 复制代码

tee ~/tts/gunicorn.conf <<-'EOF'
# gunicorn.conf
# 并行工作进程数
workers = 4
# 指定每个工作者的线程数
threads = 2
# 监听内网端口5000
bind='0.0.0.0:2020'
# 设置守护进程,将进程交给supervisor管理
daemon = 'false'
# 工作模式协程
worker_class = 'gevent'
# 设置最大并发量
worker_connections = 2000
# 设置进程文件目录
pidfile = 'gunicorn.pid'
# 设置访问日志和错误信息日志路径
accesslog = 'gunicorn_acess.log'
errorlog = 'gunicorn_error.log'
# 设置日志记录水平
loglevel = 'debug'
EOF
tee ~/tts/Dockerfile <<-'EOF'
FROM python:3.8.4
COPY requirements.txt ./
RUN pip install  -r requirements.txt -i https://pypi.tuna.tsinghua.edu.cn/simple
COPY . /flask_project/
WORKDIR /flask_project/
EOF
tee ~/tts/dockermake.sh <<-'EOF'
docker build -t python_tts .

容器制作与启动方法

bash 复制代码

#添加运行权限

chmod +x ./dockermake.sh

#运行脚本制作镜像

./dockermake.sh

#运行容器

bash run_python_tts

API：服务器ip:2020/dealAudio?text=欢迎使用tts&voice=xiaoxiao

text 是你需要转换的文本

voice 是配音员上面自己选
