使用令牌的WebChat控件中的语音识别能力差

Question

我在BotFramework的WebChat control中遇到语音识别问题。我正在使用令牌身份验证（Option 4 in link），但语音识别非常差。 （它没有使用我的LUIS启动等。即使说'嗨'我也在挣扎）。 dev.botframweork.com测试面板中的语音识别功能非常好，我想实现类似的功能。

编辑：

我的代码（或多或少，没有附加条件等）

var botSettings = {
    user: {
        id: 'You'
    },
    resize: 'detect',
    webSocket: 'true'
};

if (result.chatToken) { // From URI, working fine, included just for the sake of it
    const botConnection = new BotChat.DirectLine({
            token: result.chatToken.token
        });
    botSettings.botConnection = botConnection;
}

function get(url) { // URL is pointing to my API
    return fetch(url, {
         method: 'GET'
    }).then(res => res.text());
}

speechOptions = {
    speechRecognizer: new CognitiveServices.SpeechRecognizer({
        fetchCallback: () => get(voiceUrl),
        fetchOnExpiryCallback: () => get(voiceUrl)
    }),
    speechSynthesizer: new BotChat.Speech.BrowserSpeechSynthesizer({
        fetchCallback: () => get(voiceUrl),
        fetchOnExpiryCallback: () => get(voiceUrl),
        gender: CognitiveServices.SynthesisGender.Male,
        voiceName: 'Microsoft Server Speech Text to Speech Voice (en-US, BenjaminRUS)'
    })
};

botSettings.speechOptions = speechOptions;

BotChat.App(botSettings, document.getElementById("bot"));
