How to modify amazon lex output voice?

I am trying to create a voice bot with aws lex.

In that one of the intents response is "Your incident INC11111111 is closed"(text).

The above response is coming from a lambda function. Please check the code below.

let response = (event, data) => {
    let lambda_response = {     
   "sessionAttributes": {
      "incidentNo":  event.currentIntent.slots.INCIDENT_NO,
    },   
    "dialogAction": {     
        "type": "Close",
        "fulfillmentState": "Fulfilled",
        "message": {       
           "contentType": "PlainText",
           "content": "Hi " + data["User ID"].split('.')[0]+", Your Incident Number " +  "INC"+event.currentIntent.slots.INCIDENT_NO+ " is ," + data["Status"]
        },    
     } 
    };

    return lambda_response;
};

Ex Incident No: INC11111111

But the voice output is "your incident INC 1 crore 11 lakhs 11 thousand 1hundered eleven is closed".

What I am expecting is "Your incident INC ONE ONE ONE ONE ONE ONE ONE ONE is closed. thank you in advance.

Solution

You need to utilise SSML(Speech Synthesis Markup Language)

Using SSML tags, you can customize and control aspects of speech, such as pronunciation, volume, and speech rate.

There are a variety of directives that you can use in SSML to pronounce things differently. In your case say-as directive can be useful.

As per the question edit, try these changes

    "message": {       
       "contentType": "SSML",
       "content": "<speak> Hi " + data["User ID"].split('.')[0]+", Your Incident Number <say-as interpret-as="characters">" +  "INC"+event.currentIntent.slots.INCIDENT_NO+ "</say-as> is ," + data["Status"] +"</speak>"
    },
