概述
paddlespeech是百度飞桨平台的开源工具包，主要用于语音和音频的分析处理，其中包含多个可选模型，提供语音识别、语音合成、说话人验证、关键词识别、音频分类和语音翻译等功能。
paddlespeech整体是比较简单易用的，但是安装部署依然有很多坑，本文为探坑而写。
环境
centos 7.9
gcc 版本 7.3.0 (GCC)
OpenSSL 1.1.1
Python 3.10.3
pip 23.2.1
numpy==1.23
paddlepaddle 2.4.2 2.5.1 为什么会有两个版本，后面会讲到。
paddlespeech 1.4.1
安装步骤
安装步骤如下。
gcc 7.3.0
openssl 1.1.1
python 3.10.3
paddlepaddle 2.5.1
paddlespeech 1.4.1
基础依赖库
首先升级centos7到最新版本，安装一些基础依赖库
yum install zlib-devel bzip2-devel openssl-devel ncurses-devel sqlite-devel readline-devel tk-devel gcc make libffi-devel wget
gcc
centos7环境，默认的gcc版本是4.8.5，而paddlepaddle要求libstdc++.so.6支持GLIBCXX_3.4.20版本，需要首先安装gcc的高版本。
gcc 7.3.0版本安装，网上文章很多，略过。
openssl
python3.10要求openssl版本1.1.1。
wget http://www.openssl.org/source/openssl-1.1.1.tar.gz
tar -zxvf openssl-1.1.1.tar.gz
cd openssl-1.1.1
./config --prefix=/usr/local/openssl shared zlib
make
make install
mv /usr/bin/openssl /usr/bin/openssl.bak
ln -s /usr/local/openssl/bin/openssl /usr/bin/openssl
ln -s /usr/local/openssl/lib/libssl.so.1.1 /usr/lib64/libssl.so.1.1
ln -s /usr/local/openssl/lib/libcrypto.so.1.1 /usr/lib64/libcrypto.so.1.1
openssl version
python
python选择3.10版本。
wget https://www.python.org/ftp/python/3.10.3/Python-3.10.3.tgz
tar -zxvf Python-3.10.3.tgz
cd Python-3.10.3
./configure -C --with-openssl=/usr/local/openssl --with-openssl-rpath=auto --prefix=/usr/local/python3
make -j 8
make altinstall
ln -s /usr/local/python3/bin/python3.10 /usr/bin/python3
ln -s /usr/local/python3/bin/pip3.10 /usr/bin/pip3
python3 -V
Python 3.10.3
更换pip源
mkdir -p ~/.pip
touch ~/.pip/pip.conf
vi ~/.pip/pip.conf
[global]
index-url=https://mirrors.aliyun.com/pypi/simple/
[install]

paddlepaddle
paddlepaddle需要2个版本，分别配合ASR和TTS使用。

st功能依赖全失败，未测试成功。
总结
paddlespeech提供了语音相关的基础能力，降低了音频模型的使用门槛。
在paddlespeech的基础上，完善的产品还需要很多的包装工作和业务开发。
