Pyttsx3 выдает ошибку, когда я даю ввод более одного раза в Flask приложении

Вот мой flask python код 

@app.route("/text-to-speech", methods=['POST'])
def tts():
    userText = request.form['msg']
    engine = pyttsx3.init()
    engine.say(userText)
    engine.runAndWait()
    return render_template('tts.html')

, и это tts. html

<!DOCTYPE html>
<html lang="en">
<head>
    <meta http-equiv="Content-Type" content="text/html; charset=utf-8" />
    <link rel="stylesheet" type="text/css" href= "{{ url_for('static',filename='styles/chatter.css') }}" />
    <link rel="stylesheet" href="https://cdnjs.cloudflare.com/ajax/libs/font-awesome/4.7.0/css/font-awesome.min.css">
    <script src="https://ajax.googleapis.com/ajax/libs/jquery/3.4.1/jquery.min.js"></script>
</head>
<body>
<div id="home">
    <a href="/">Home <i class="fa fa-home"></i></a>
</div>
<h1>Text-to-Speech</h1>
<div>
    <div id="chatimage">
        <img src="{{url_for('static', filename='images/image.png')}}" alt="joe">
    </div>
    <div id="chatbox">
        <p class="botText"><span>>>TTS</span></p>
    </div>
    <div id="userInput">
        <form method="POST">
            <label for="textInput"></label>
            <input id="textInput" type="text" name="msg" placeholder="">
            <input id="buttonInput" type="submit" value="Read">
        </form>
    </div>
</div>
</body>
</html>

При первом вводе предложения это читай как надо. Если я пытаюсь ввести второй раз, я получаю 

builtins.RuntimeError
RuntimeError: run loop already started

, который ломает мою страницу.

Это вся страница с ошибкой: 

builtins.RuntimeError
RuntimeError: run loop already started

Кто-нибудь знает, что мне делать? Есть ли способ убить двигатель или что-то в этом роде, чтобы он был заново инициализирован?
