个必需参数： <code>Interface(fn, inputs, outputs, ...)</code></p> <p data-svelte-h="svelte-gqxxez">这些参数的含义是：</p> <ul data-svelte-h="svelte-1k2if01"><li><code>fn</code> ：由 Gradio 接口包装的预测函数。该函数可以接受一个或多个参数并返回一个或多个值</li> <li><code>inputs</code> ：输入组件类型。Gradio 提供了许多预构建的组件，例如 <code>image</code> 或 <code>mic</code> 。</li> <li><code>outputs</code> ：输出组件类型。同样，Gradio 提供了许多预构建的组件，例如 <code>image</code> 或 <code>label</code> 。</li></ul> <p data-svelte-h="svelte-cf195f">可以使用组件的完整列表请参阅 <a href="https://gradio.app/docs" rel="nofollow">Gradio 文档</a> 。每个预构建的组件都可以通过实例化该组件对应的类来定制。</p> <p data-svelte-h="svelte-17o6fl6">例如，正如我们在 <a href="/course/chapter9/2">前一小节</a> 中看到的，你可以将一个 <code>Textbox(lines=7, label="Prompt")</code> 组件传递给 <code>inputs</code> 参数，而不是将 <code>"textbox"</code>

data-svelte-h="svelte-14ytwgm">如前所述，Gradio 提供了许多不同的输入和输出组件。因此，让我们构建一个适用于音频的 <code>Interface</code> 。</p> <p data-svelte-h="svelte-joy6oa">在这个例子中，我们将构建一个输入和输出都是音频的函数，它可以接收一个音频文件后将其反转并返回。</p> <p data-svelte-h="svelte-6lotiv">我们将使用 <code>Audio</code> 组件作为输入。使用 <code>Audio</code> 组件时，你可以通过 <code>source</code> 指定输入音频的方式是上传的音频文件还是通过麦克风实时录制的声音。在这个例子中，让我们将其设置为“麦克风”。为了让交互更加友好，我们会在我们的 <code>Audio</code> 上添加一个标签，上面写着“Speak here.”。</p> <p data-svelte-h="svelte-1fbke88">此外，我们希望函数接收的音频是 <code>numpy</code> 数组格式，这样我们可以轻松地“反转”它。因此我们将 <code>"type"</code> 设置为 <code>"numpy"</code> ，它会将传递输入 data 转换为 <code>(sample_rate,data)</code> 的元组输入到我们的函数。</p> <p data-svelte-h="svelte-19r0yoy">我们还将使用 <code>Audio</code> 作为输出组件，它可以自动将根据采样率和音频数据将 numpy 数组渲染为可播放的音频文件。因此，在这个例子中不需要对输出组件进行修改，只需要传递一个 <code>"audio"</code> 字符串。</p> <div class="code-block relative "><div class="absolute top-2.5 right-4"><button class="inline-flex items-center relative text-sm focus:text-green-500 cursor-pointer
