编写 pywebview_tts.py 如下

# -*- coding: utf-8 -*-
""" pywebview 和 http交互的例子 """
import os
import webview
#import threading
import win32com.client  # TTS
speaker = win32com.client.Dispatch("SAPI.SpVoice")

os.chdir('/python')

class Api:
    """ pywebview Api """
    def speak(self,txt):
        """ text TTS """
        if txt.strip() !='':
            speaker.Speak(txt)

# main()
api = Api()
window = webview.create_window('JSBridge 调用TTS示例', 
                            url="http://localhost:8888/", 
                            js_api=api, width=1000, height=800)
webview.start(gui='cef', debug=False)

编写 index3.html 如下

web 服务程序参见: python：mdict + bottle = web 查询英汉词典

记得：将其中 index.html 改为 index3.html

先运行 python mdict_bottle.py , 再运行 python pywebview_tts.py
