How can I switch languages using Rasa Pro CALM

Rasa CALM

post by palacio on Dec 5, 2024

I’m just getting to grips with rasa. I need to make something like a start message where I suggest choosing one of the two suggested languages for further bot responses. I saw in config.yml there is a language for llm, I understand it also needs to be changed. I also assume that for the language it will be necessary to create a slot in domain.yml and also validate it via actions. I hope for your understanding, I could not find this information in the documentation.

The latest version of Rasa Pro v3.12 has added some multi-language features as follows:

• Multi-language support was implemented to enable the assistant to deliver localized responses and flow names that dynamically adjust to the user’s language preference. In particular:
  • The default language is defined using the language key in config.yml, while additional supported languages are specified under additional_languages.
  • A translation section was introduced for responses to provide language-specific versions of the response text.
  • A translation section was added for flows to define localized flow names.
  • The rephraser prompt now accommodates the selected language.
  • Validation mechanisms were implemented to ensure proper use of translations; the CLI command rasa validate data translations is available for verification.
  • A new slot type, StrictCategoricalSlot, was developed to restrict its values to a predefined set.
  • A built-in language slot of the StrictCategoricalSlot type was added for managing translations effectively.
