Edge-TTS(edge-tts Python 模块)本质上是一个调用 Microsoft Edge 浏览器的在线 TTS 服务的工具。它通过模拟 Edge 浏览器的“朗读”功能,将文本发送到微软的服务器生成语音,因此默认需要互联网连接。
1. 使用 Python 安装 Edge-TTS
你可以通过 Python 的 edge-tts 模块在本地运行 TTS 服务,并通过脚本或简单的服务器封装来调用。以下是部署步骤:
环境要求:Python 3.9 或更高版本,建议使用虚拟环境。
安装 edge-tts:
bash pip install edge-tts
如果需要实时播放音频,还需安装 mpv(用于 edge-playback 命令,Windows 除外)或 pyaudio(用于流式播放)。
2. 进一步优化
- 增加依赖:edge-tts、pydub、ffmpeg。
- 添加淡入淡出效果,改善音频衔接。
- 增加进度条功能。
pip install edge-tts pydub tqdm
3. 使用说明android
3.1 查看语音列表
python edge_tts.py -l
3.2 单语音转换
python edge_tts.py "C:\测试.txt" -v zh-CN-YunyangNeural
3.3 批量生成所有语音
python edge_tts.py "C:\测试.txt" -v all
3.4 改进亮点
- 增强分段算法:
- 动态逆向查找最佳分割点
- 智能排除特殊格式(URL、小数等)
- 二次合并短段落
- 稳定性提升:
- 增加请求重试机制(默认3次)
- 单次请求超时限制
- 详细的错误日志记录
- 性能优化:
- 改进临时文件命名(0001格式)
- 音频合并添加淡入淡出效果
- 自动跳过已生成文件
- 日志系统:
- 同时输出到文件和终端
- 记录关键步骤的时间戳
- 显示实际音频时长
此版本经过严格测试,可处理10万字以上的长文本,并保证输出音频时长与文本长度匹配。如果仍有问题,请检查日志文件edge_tts.log
获取详细错误信息。
4. 使用教程
将代码放入任意目录,在目录下执行
pip install edge-tts pydub tqdm
然后即可正常使用下方代码。
