Jovo Model: Alexa
Learn how to turn the Jovo Model into an Alexa Interaction Model.
- Alexa-specific Elements in the Jovo Model
- Using the Alexa Jovo Model with the Jovo CLI
- Using the Alexa Jovo Model npm Package
Language models for Amazon Alexa Skills are called Alexa Interaction Models. You can either manage them via API (what the Jovo CLI is doing during deployment) or in the Amazon Developer Portal, which offers a graphical user interface.
Alexa Interaction Models include:
- Invocation name
- Intents with samples (phrases in the Jovo Model) and slots (inputs)
- Slot types (input types)
This section provides an overview how the Jovo Model (see general structure in the main Jovo Model docs) can be extended with platform-specific content for Alexa.
You can define an Alexa-specific invocation name like this:
Find all built-in slot types in the official Alexa Slot Type Reference.
If your intent uses an input (see how they are added to the Jovo Model) that requires an Alexa built-in slot type, you can add it like this:
Some elements (intents, slot types) might be required only by the Alexa portion of your Jovo project. For this you can add an
alexa object to your Jovo Model.
This object follows the structure of the Alexa Interaction Model JSON, notice the difference of
samples instead of
phrases, for example.
By using the
jovo build command, you can turn your Jovo Model files in the
models folder in your Jovo project into Alexa specific files. You can find the files inside the
platforms/alexaSkill folder that is created by the Jovo CLI. It contains all the information of your Alexa Skill needed to deploy the skill to the Amazon Developer Portal.
The Jovo CLI uses the ASK CLI for deployment and supports both ASK CLI
v1, each requiring a slightly different project structure. We recommend to upgrade your ASK CLI and migrate to the new ASK structure. Read more about the migration here.
jovo deploy command then uses these files and uploads them to the Alexa platform where you can see changes in the Alexa Developer Console.

This is where your generated Alexa Interaction Models live.
Additionally, there are also some other files and folders that are important for your Alexa project.
.ask folder contains the basic deploy settings of your skill, such as your project's
skillId, inside a single file,
ask-states.json for v2 of the
config for v1. We recommend you to not make any changes to these files.
skill.json contains the publication and configuration information of your Skill. This can be either updated manually or in the Amazon Developer Portal (and then imported with the
jovo get command). If you have v2 of the
ASK CLI installed, the file's location is
alexaSkill/skill-package/, else it's located inside
V2 of the
ASK CLI requires an additional file,
ask-resources.json. This file contains your project's configuration for use with the Skill Management API.
Install the package like this:
