java - Google助理只能用英语回答，但永远不会

Question

我正在使用Google Actions Java SDK编写Google Assistant应用，并且想在对话中使用德语。在action.json中，我设置了语言环境“ de”，这应该可以解决问题，但唯一改变的是调用语句，该语句将用德语读出，并且一旦应用程序响应被读出，语音就会变为英语之一。

我已经删除了项目中的所有英语语言设置，并且Google控制台的对话语言也是德语。在action.json中使用本地de-DE会导致以下错误：


选择了语言环境de-DE，但是未选择语言de。

{
  "locale": "de",
  "actions": [
    {
      "description": "Default Welcome Intent",
      "name": "MAIN",
      "fulfillment": {
        "conversationName": "conversation_1"
      },
      "intent": {
        "name": "actions.intent.MAIN"
      }
    }
  ],
  "conversations": {
    "conversation_1": {
      "name": "conversation_1",
      "url": "fulfillment.url",
      "fulfillmentApiVersion": 2
    }
  }
}

遵循我从 Google Example App获得的webhook，但根据自己的需要对其进行了定制：

塞尔维尔特

@WebServlet(name = "actions", value = "/")
public class ActionsServlet extends HttpServlet {
  private static final Logger LOG = LoggerFactory.getLogger(ActionsServlet.class);
  private final App actionsApp = new NumberAction();

  @Override
  protected void doPost(HttpServletRequest req, HttpServletResponse res) throws IOException {
    String body = req.getReader().lines().collect(Collectors.joining());
    LOG.info("doPost, body = {}", body);

    try {
      String jsonResponse = actionsApp.handleRequest(body, getHeadersMap(req)).get();
      LOG.info("Generated json = {}", jsonResponse);
      res.setContentType("application/json");
      res.setCharacterEncoding("UTF-8");
      writeResponse(res, jsonResponse);
    } catch (InterruptedException e) {
      handleError(res, e);
    } catch (ExecutionException e) {
      handleError(res, e);
    }
  }

  @Override
  protected void doGet(HttpServletRequest request, HttpServletResponse response)
      throws IOException {
    response.setContentType("text/plain");
    response
        .getWriter()
        .println("ActionsServlet is listening but requires valid POST request to respond with Action response.");
  }

  private void writeResponse(HttpServletResponse res, String asJson) {
    try {
      res.getWriter().write(asJson);
    } catch (IOException e) {
      e.printStackTrace();
    }
  }

  private void handleError(HttpServletResponse res, Throwable throwable) {
    try {
      throwable.printStackTrace();
      LOG.error("Error in App.handleRequest ", throwable);
      res.getWriter().write("Error handling the intent - " + throwable.getMessage());
    } catch (IOException e) {
      e.printStackTrace();
    }
  }

  private Map<String, String> getHeadersMap(HttpServletRequest request) {
    Map<String, String> map = new HashMap();

    Enumeration headerNames = request.getHeaderNames();
    while (headerNames.hasMoreElements()) {
      String key = (String) headerNames.nextElement();
      String value = request.getHeader(key);
      map.put(key, value);
    }
    return map;
  }
}

ActionSdkApp

public class NumberAction extends ActionsSdkApp {

  private static final Logger LOGGER = LoggerFactory.getLogger(NumberAction.class);

  @ForIntent("actions.intent.MAIN")
  public ActionResponse welcome(ActionRequest request) {
    LOGGER.info("Welcome intent start.");
    ResponseBuilder responseBuilder = getResponseBuilder(request);
    ResourceBundle rb = ResourceBundle.getBundle("resources", request.getLocale());
    responseBuilder.add(rb.getString("welcome"));
    responseBuilder.getConversationData().put("conversationToken", "Some Session");
    LOGGER.info("Welcome intent end.");
    return responseBuilder.build();
  }

  @ForIntent("actions.intent.TEXT")
  public ActionResponse number(ActionRequest request) {
    LOGGER.info("Number intent start.");
    ResponseBuilder responseBuilder = getResponseBuilder(request);
    ResourceBundle rb = ResourceBundle.getBundle("resources");

    String convToken = (String) request.getConversationData().get("conversationToken");
    String answer = NumberFulfillment.doFulfillment(request.getArgument("text").getTextValue(),Datastore.getInstance().getSession(convToken));
    responseBuilder.add(answer);

    LOGGER.info("Number intent end.");
    return responseBuilder.build();
  }
}

不同的Google Actions项目中的相同代码可以正常工作。
