Detect User Language : Oracle Bots

Oracle Bot comes with a very sophisticated language detection and translation service. You can attach either a Microsoft or Google service to the environment and make use of it within your bot. Oracle Bots dev guide talks about it : https://docs.oracle.com/en/cloud/paas/mobile-suite/develop/localization.html#GUID-997ED305-D011-4E89-9440-566092A4870A

But, these translation services are not free. So for my development purposes I created a custom component, which does the same for me but for FREE.

Introducing Yandex APIs (https://tech.yandex.com/translate/). It is simple and easy to use. And most importantly it is free.
Yandex supports over 90 different languages. The only thing you need to do is, register and create an API key for yourself.

Step 1:
Register and create an API key : https://translate.yandex.com/developers/keys

Step 2:
Download the custom component from my GitHub : https://github.com/sohamda/CustomComponents/tree/master/detect_language

Step 3:
Update the "detect_language.js" and add your key to the detectLanguage() function.

Step 4:
Update "registry.js" to add this new custom component.

'DetectLanguage': require('./detect_language/detect_language')

Step 5:
Add a string variable in the dialog flow, named "detectedLocale".

detectedLocale: "string"

Then update the dialog flow to use this custom component, followed by a "Switch" component in order to decide what to do once you detected the language.

detectLanguage:
  component: "DetectLanguage"
switch:
  component: "System.Switch"

  properties:
    variable: detectedLocale
    source:
      values:
 - "en"
 - "nl"
  transitions:
    actions:
      en: <ENGLISH_STATE>
      nl: <DUTCH_STATE>
      NONE: <EXCPETION_STATE>

 You can use as many as transitions you want in your switch. In the above example I just did two.

Once this is done, test your bot.

That's it!.

Happy "Bot"-ing. :)
