Microsoft Botframework网络聊天语音识别动态设置语言代码

如何解决Microsoft Botframework网络聊天语音识别动态设置语言代码

我正在寻找如何根据用户说的语言在网络聊天中动态设置语言代码。

我尝试过

window.WebChat.renderWebChat({
        directLine: window.WebChat.createDirectLine({
            secret: "xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx"
        }),styleOptions: {
            hideUploadButton: true,botAvatarInitials: 'Bot'
        },selectVoice: (voices,activity) => voices.find(({
            name
        }) => /Kalpana/iu.test(name)),//Console.log(activity.locale);
        webSpeechPonyfillFactory: window.WebChat.createCognitiveServicesspeechServicesPonyfillFactory({
            region: 'xxxx',subscriptionKey: 'xxxxx'
        }),userID: "ravi@gmail.com",locale: 'hi-IN'
    },document.getElementById('webchat')
);

document.querySelector('#webchat > *').focus();

我要寻找的是，我需要根据用户说的语言动态设置 locale 参数。
