Following lambda function code returns voice from Bot.

 `public Object handleRequest(Map<String,Object> input, Context context) {

        context.getLogger().log("input" +input);
        LexRequest lexRequest = LexRequestFactory.createLexRequest(input);
        String content = String.format("<speak>Hi! Request came from:"+lexRequest.getBotName()+"</speak>",  

                lexRequest.getIntentName(),lexRequest.getCrust(),lexRequest.getPizzaKind(),lexRequest.getSize()

                );

        SessionAttributes sessionAttributes = new SessionAttributes();
        Message message = new Message("SSML",content); 

        DialogAction dialogAction = new DialogAction("Close", "Fulfilled", message);
        return new LexRespond(sessionAttributes,dialogAction);
    }`
