我正在DialogFlow上构建一个多语言教育应用程序。我遇到了一个大问题:切换识别语言。任何建议我如何实现这一目标或任何其他方法?
我已经添加到DialogFlow Web界面辅助语言。
我正在使用带有node.js webhook的谷歌sdk上的动作。
更新 :
let responseToUser = {
//fulfillmentMessages: richResponsesV2, // Optional, uncomment to enable
//outputContexts: [{ 'name': `${session}/contexts/weather`, 'lifespanCount': 2, 'parameters': {'city': 'Rome'} }], // Optional, uncomment to enable
fulfillmentText: 'This is from Dialogflow's Cloud Functions for Firebase editor! :-)', // displayed response
payload: {
audioConfig : {
"audioEncoding": 'AUDIO_ENCODING_FLAC',
"sampleRateHertz": 16000,
"languageCode": 'de',
"phraseHints": ["gutten tag"]
}
},
function sendResponse (responseToUser) {
// if the response is a string send it as a response to the user
if (typeof responseToUser === 'string') {
let responseJson = {fulfillmentText: responseToUser}; // displayed response
response.json(responseJson); // Send response to Dialogflow
} else {
// If the response to the user includes rich responses or contexts send them to Dialogflow
let responseJson = {};
// Define the text response
responseJson.fulfillmentText = responseToUser.fulfillmentText;
responseJson.payload = responseToUser.payload;
// Send the response to Dialogflow
console.log('Response to Dialogflow: ' + JSON.stringify(responseJson));
response.json(responseJson);

对话流需要音频请求的语言,如果要更改该语言,则需要发出新请求。 您可以在 webhook 和前端中实现一些逻辑,以使用其他语言再次尝试请求。
为此,请在 webhook 响应响应的有效负载字段中添加一些数据,指示您希望使用指定的其他语言发出新请求。 在客户端中,检查响应有效负载中的数据,如果数据指示使用另一种语言重试,请使用输入音频配置中指定的不同语言发送另一个请求,并使用相同的音频。
