Please refer below for the translation behavior:

Response Types Components Translation Behavior
Plain Text Responses Refers to plain text responses defined anywhere in the virtual assistant. For example, prompts, responses etc., Default: Auto-translated

You can choose to translate only a specific part of the response by using the koreUtil.autoTranslate function only for that part.

Advanced / JavaScript based Responses Refers to responses defined using JavaScript. For example, prompts, responses etc., Default: No auto-translation

You can use the AutoTranslation function inside the JavaScript to define the parts of the responses that need translation.
Auto-formatted Responses Refers to the responses that are auto-formatted by the platform as per the channel specifications. For example, confirmations, list of values, ambiguities etc. Default: Auto-translated

Usage Example:

koreUtil.autoTranslate();

Here are a few use case examples for your reference:

Use Case-1:To translate part of a sentence in the user’s language:

Example:

{{koreUtil.autoTranslate('Welcome! I am a virtual assistant powered by ')}} General Insurance

Output in Serbian

Добредојдовте! Јас сум виртуелен асистент напојуван од General Insurance

Use Case-2:To translate the content of a customized JavaScript template, then use koreUtil.autoTranslate as follows:

Example:

var accountBalance = getbalance(); var message = koreUtil.autoTranslate("Your account balance is "); var message = message.concat(env.currency, ‘ ’, accountBalance); print(message);

Output in Serbian

Баланс вашего счета USD 5,278.00

Use Case-3: To translate the bot responses in a particular language by passing the language code. An example where the bot will respond only in German even though the user is interacting in any language:

Example

var message = koreUtil.autoTranslate("This is a sample message", de);print(message);

Output in German

    "title": info.list_of_languages[i].title,
    "payload": info.list_of_languages[i].value
    };

  message.payload.buttons.push(button);
 }
print(JSON.stringify(message));

Usage Example 2: To get the standard response for “Ask if the user would like to switch to any of the new languages detected during a conversation”

koreUtil.autoTranslate

koreUtil.autotranslate is a platform function that lets you automatically translate the virtual assistant response from a language in which the bot is configured to the language in which the user is interacting or a language of your choice. This function uses a translation engine to translate the bot responses into user input language. For more information on how to configure a translation engine, refer here.

Please refer below for the translation behavior:

Response Types Components Translation Behavior
Plain Text Responses Refers to plain text responses defined anywhere in the virtual assistant. For example, prompts, responses etc., Default: Auto-translated

You can choose to translate only a specific part of the response by using the koreUtil.autoTranslate function only for that part.

Advanced / JavaScript based Responses Refers to responses defined using JavaScript. For example, prompts, responses etc., Default: No auto-translation

You can use the AutoTranslation function inside the JavaScript to define the parts of the responses that need translation.
Auto-formatted Responses Refers to the responses that are auto-formatted by the platform as per the channel specifications. For example, confirmations, list of values, ambiguities etc. Default: Auto-translated

Usage Example:

koreUtil.autoTranslate();

Here are a few use case examples for your reference:

Use Case-1:To translate part of a sentence in the user’s language:

Example:

{{koreUtil.autoTranslate('Welcome! I am a virtual assistant powered by ')}} General Insurance

Output in Serbian

Добредојдовте! Јас сум виртуелен асистент напојуван од General Insurance

Use Case-2:To translate the content of a customized JavaScript template, then use koreUtil.autoTranslate as follows:

Example:

var accountBalance = getbalance(); var message = koreUtil.autoTranslate("Your account balance is "); var message = message.concat(env.currency, ‘ ’, accountBalance); print(message);

Output in Serbian

Баланс вашего счета USD 5,278.00

Use Case-3: To translate the bot responses in a particular language by passing the language code. An example where the bot will respond only in German even though the user is interacting in any language:

Example

var message = koreUtil.autoTranslate("This is a sample message", de);print(message);

Output in German

Dies ist eine Beispielnachricht
