Localizing Spoken Responses

In Chapter 1, ​Alexa, Hello​, as we began work on the Star Port 75 Travel skill, we added a LocalisationRequestInterceptor object in index.js and registered it with the skill builder. As a reminder, here’s what LocalisationRequestInterceptor looks like:

locale/starport-75/lambda/index.js

const LocalisationRequestInterceptor = {
    process(handlerInput) {
        i18n.init({
            lng: Alexa.getLocale(handlerInput.requestEnvelope),
            resources: languageStrings
        }).then((t) => {
            handlerInput.t = (...args) => t(...args);
        });
    }
};

The ASK SDK gives us the option of registering one or more request intercepters in the skill. Such interceptors may inspect and modify the handlerInput object before giving it to a request handler. ...
