准备工作
- txt电子书
- 网络
- 安装好edge-tts
$ pip install edge-tts - 安装好Python3
基础用例
$ edge-tts --text "Hello, world!" --write-media hello.mp3 --write-subtitles hello.vtt
更多用例，可参阅Edge-tts Usage。
用Python把电子书拆分成小的章节
假设我们有名为“白鹿原.txt”的电子书。在该电子书的同级目录下，创建“split.py”文件，把下方代码粘贴进去。

# 打开电子书
with open("白鹿原.txt", "r") as input_file:
# 读电子书的内容
file_contents = input_file.read()
# 用“\n\n第”来分隔不同的章节(不同的电子书结构不同，请手动确认分隔符)
file_chunks = file_contents.split("\n\n第")
# 分割电子书
for i, file_chunk in enumerate(file_chunks):
# 为输出的电子书命名
output_filename = f"白鹿原_{i+1}.txt"
# 打开输出的电子书
with open(output_filename, "w") as output_file:
# 写入分割出来的内容，并在命令行提示结果
output_file.write("第" + file_chunk)
print("\n finishing %s" % output_file)
# 完成
print ("done.")
用edge-tts把章节转换成mp3
把输出的章节txt统一放入“splitted”文件夹中，在该文件夹中创建“txt_to_audio.py”文件，把下方代码粘贴进去：

import os
import subprocess
# 指定工作目录和输出文件夹
txt_path = "./"
output_folder = "output"
# 创建输出文件夹
if not os.path.exists(output_folder):
os.makedirs(output_folder)
# 遍历该目录下的所有txt文件
for txt_file in os.listdir(txt_path):
# 检查是否是txt文件
if txt_file.endswith(".txt"):
# 创建终端命令(参考edge-tts命令)
cmd = f"edge-tts -f {txt_path}/{txt_file} --write-media {output_folder}/{txt_file[:-4]}.mp3 --write-subtitles {output_folder}/{txt_file[:-4]}.vtt --voice zh-CN-XiaoxiaoNeural --rate=+10%"
# 执行终端命令，输出执行状态
print('file %s is being processed...' % txt_file)
subprocess.run(cmd, shell=True)
print('file %s completed.' % txt_file)
等待完成
用到的是在线文字生成语音技术，等待任务完成即可收获mp3文件。
