IOs speech recognition does not work with an input hint of expecting input

[rosskyl]

I am using the direct line with the code below. I have speech recognition working with IOs but when a response with the input hint set to expecting input comes back, speech recognition becomes unusable until I send something back. This often happens with PromptDialog.Confirm. Since IOs does not allow audio recording unless done from a direct user tap/click, I am guessing the problem is with the speech recognizer trying to start recording audio but it can't.

const user = {
    id: document.getElementById("userId").value,
    name: document.getElementById("userName").value
};

const bot = {
    id: params['botid'] || 'botid',
    name: params['botname'] || 'botname'
};

window.botchatDebug = params['debug'] && params['debug'] === 'true';

var speechOptions;
if (Modernizr.speechsynthesis) {
    speechOptions = {
        speechRecognizer: new CognitiveServices.SpeechRecognizer({
            fetchCallback: (authFetchEventId) => getBingToken(),
            fetchOnExpiryCallback: (authFetchEventId) => getBingToken()
        }),
        speechSynthesizer: new BotChat.Speech.BrowserSpeechSynthesizer()
    };
}
else {
    speechOptions = null;
}

var botConnection = new BotChat.DirectLine({
    domain: params['domain'],
    token: document.getElementById("directLineToken").value, 
    webSocket: params['webSocket'] && params['webSocket'] === 'true' // defaults to true
});

BotChat.App({
    bot: bot,
    locale: params['locale'],
    resize: 'detect',
    speechOptions: speechOptions,
    user: user,
    botConnection: botConnection
}, document.getElementById('BotChatGoesHere'));

var isSafari = /^((?!chrome|android).)*safari/i.test(navigator.userAgent);

function SpeakText() {
    var msg = new SpeechSynthesisUtterance();
    window.speechSynthesis.speak(msg);

    document.getElementsByClassName("wc-mic")[0].removeEventListener("click", SpeakText);
}

if (isSafari) {

    window.addEventListener("load", function () {
        document.getElementsByClassName("wc-mic")[0].addEventListener("click", SpeakText);
    });
}

// Needed to change between the two audio contexts
var AudioContext = window.AudioContext || window.webkitAudioContext;

// Sets the old style getUserMedia to use the new style that is supported in more browsers even though the framework uses the new style
window.navigator.getUserMedia = function (constraints, successCallback, errorCallback) {
    window.navigator.mediaDevices.getUserMedia(constraints)
        .then(function (e) {
            successCallback(e);
        })
        .catch(function (e) {
            errorCallback(e);
        });
};
