使用 Kivy 应用程序调用 MS Azure 语音识别

Question

我正在使用 Kivy 2.0.0 构建一个 Python 应用程序。我想时不时地访问 Kivy 的循环并调用语音识别。语音识别在您按下一个按钮后开始，在按下另一个按钮后结束。然后，这种语音识别将其结果存储到一个变量（result）中，并将其显示在屏幕上的一个标签上，其文本定义为term_text.

我写了这段代码，我预计它会起作用，但它不会。你能帮帮我吗？
这是我得到的错误...

文件“字符串”，第 22 行，在模块中类型错误：listen() 缺少 1 个必需的位置参数：'dt'

Answer 1

如错误所述：

listen() missing 1 required positional argument: 'dt'

所以你只需要提供一个dt参数。尝试更改：

on_press: root.listen()

至：

on_press: root.listen(0)
