科大讯飞在线语音合成（流式版）python版
1、进入自己的项目
复制APPID、APISecret、APIKey
2、添加好听发音人
复制vcn参数
3、需要替换代码部分：
换自己喜欢的发声人的参数
换上自己的APPID、APISecret、APIKey
4、完整代码：

3、播放MAV文件
from playsound import playsound# 播放 WAV 文件
playsound("output.wav")4、转MP3文件
from pydub import AudioSegmentsong = AudioSegment.from_wav("output.wav")
song.export("demo.mp3", format="mp3")
