在 Dialogflow 中探索
点击继续,将我们的响应示例导入 Dialogflow 中。然后,按照以下步骤部署和测试该示例:
- 输入代理名称并为示例创建新的 Dialogflow 代理。
- 代理导入完成后,点击转至代理 (Go to agent)。
- 在主导航菜单中,前往 Fulfillment。
- 启用内嵌编辑器,然后点击部署。编辑器包含示例代码。
- 在主导航菜单中,点击 Integrations(集成),然后点击 Google Assistant。
- 在显示的模态窗口中,启用 Auto-preview changes,然后点击 Test 打开 Actions 模拟器。
- 在模拟器中,输入
Talk to my test app
以测试示例!
简单响应在视觉上以聊天气泡的形式呈现,并使用文字转语音 (TTS) 或语音合成标记语言 (SSML) 发出声音。
默认情况下,TTS 文本用作聊天气泡内容。如果该文本的视觉方面符合您的需求,您就不需要为聊天气泡指定任何显示文本。
您还可以查看我们的对话设计指南,了解如何在 Action 中融入这些视觉元素。
属性
简单响应具有以下要求和您可以配置的可选属性:
- 支持具有
actions.capability.AUDIO_OUTPUT
或actions.capability.SCREEN_OUTPUT
功能的 Surface。 每个聊天气泡不得超过 640 个字符。超过该限制的字符串将在第一个单词换行(或空格)超过 640 个字符时被截断。
聊天气泡内容必须是 TTS/SSML 输出的语音子集或完整转录内容。这有助于用户标出您的语音内容,并提高其在各种条件下的理解。
每轮最多 2 个聊天气泡。
您提交给 Google 的聊天头像(徽标)必须为 192x192 像素,并且不能使用动画格式。
示例代码
Node.js
app.intent('Simple Response', (conv) => { conv.ask(new SimpleResponse({ speech: `Here's an example of a simple response. ` + `Which type of response would you like to see next?`, text: `Here's a simple response. ` + `Which response would you like to see next?`, })); });
Java
@ForIntent("Simple Response") public ActionResponse welcome(ActionRequest request) { ResponseBuilder responseBuilder = getResponseBuilder(request); responseBuilder.add( new SimpleResponse() .setTextToSpeech( "Here's an example of a simple response. " + "Which type of response would you like to see next?") .setDisplayText( "Here's a simple response. Which response would you like to see next?")); return responseBuilder.build(); }
Node.js
conv.ask(new SimpleResponse({ speech: `Here's an example of a simple response. ` + `Which type of response would you like to see next?`, text: `Here's a simple response. ` + `Which response would you like to see next?`, }));
Java
ResponseBuilder responseBuilder = getResponseBuilder(request); responseBuilder.add( new SimpleResponse() .setTextToSpeech( "Here's an example of a simple response. " + "Which type of response would you like to see next?") .setDisplayText( "Here's a simple response. Which response would you like to see next?")); return responseBuilder.build();
JSON
请注意,以下 JSON 描述了 webhook 响应。
{ "payload": { "google": { "expectUserResponse": true, "richResponse": { "items": [ { "simpleResponse": { "textToSpeech": "Here's an example of a simple response. Which type of response would you like to see next?", "displayText": "Here's a simple response. Which response would you like to see next?" } } ] } } } }

SSML 和声音
在响应中使用 SSML 和声音可以使其更加完善,并改善用户体验。以下代码段展示了如何创建使用 SSML 的响应:
Node.js
app.intent('SSML', (conv) => { conv.ask(`<speak>` + `Here are <say-as interpet-as="characters">SSML</say-as> examples.` + `Here is a buzzing fly ` + `<audio src="https://actions.google.com/sounds/v1/animals/buzzing_fly.ogg"></audio>` + `and here's a short pause <break time="800ms"/>` + `</speak>`); conv.ask('Which response would you like to see next?'); });
Java
@ForIntent("SSML") public ActionResponse ssml(ActionRequest request) { ResponseBuilder responseBuilder = getResponseBuilder(request); responseBuilder.add( "<speak>" + "Here are <say-as interpet-as=\"characters\">SSML</say-as> examples." + "Here is a buzzing fly " + "<audio src=\"https://actions.google.com/sounds/v1/animals/buzzing_fly.ogg\"></audio>" + "and here's a short pause <break time=\"800ms\"/>" + "</speak>"); return responseBuilder.build(); }
Node.js
conv.ask(`<speak>` + `Here are <say-as interpet-as="characters">SSML</say-as> examples.` + `Here is a buzzing fly ` + `<audio src="https://actions.google.com/sounds/v1/animals/buzzing_fly.ogg"></audio>` + `and here's a short pause <break time="800ms"/>` + `</speak>`); conv.ask('Which response would you like to see next?');
Java
ResponseBuilder responseBuilder = getResponseBuilder(request); responseBuilder.add( "<speak>" + "Here are <say-as interpet-as=\"characters\">SSML</say-as> examples." + "Here is a buzzing fly " + "<audio src=\"https://actions.google.com/sounds/v1/animals/buzzing_fly.ogg\"></audio>" + "and here's a short pause <break time=\"800ms\"/>" + "</speak>"); return responseBuilder.build();

音效库
我们的音效库中提供了各种免费的简短音效。这些声音是为您托管的,因此您只需将它们包含在 SSML 中即可。
