Done and Try it out

Congratulations! You've completed the installation and  set up for Language I/O Lightning Chat. Now it's time to give it try. Normally, you would

  • Launch the service console
  • Go online using omni-channel
  • Launch a chat client with a browser language you prefer, e.g. Spanish
  • Start the chat as a client and type something in your preferred language, e.g. Spanish
  • As an agent, send a message using English
  • Translated messages will automatically display in Language I/O Chat tab in the Service Console, as well as the client chat window

Appendix: Configuration Settings

  1. Enable Translation: If checked, the translation is turned on. Messages from both agent and client will be translated. This setting is on by default.
  2. Include Original Text: If checked, the original pre-translation English in the chat will be visible to the customer as well as the translation.
  3. Use Auto Responder: Send a translated initial greeting to the customer (the auto-greeting of the chat must be disabled)
  4. Use Local Messaging: Use locally stored greetings in custom objects that come with the project
  5. Append Transcript: Append a sequence of the chat with translation activity to the transcript
  6. Unsupported Language Text: Default text to send to the user if their language or locale is not supported for translation. This text can be customized in our backend to respond to certain browser languages.
  7. Use Agent's Locale: If unchecked, assume the agent is going to speak English. If checked, use the Agent's set Salesforce locale for translation.
  8. Custom Detail Locale: A locale code can be passed in the custom details of the chat, this may be desired if neither the chat button language or the browser locale suffice.
  9. Use Chat Button Language: If checked, the language specified by the chat button is used as as the target locale for translation. Otherwise the browser language is used.
