Speechly Command Line Tool

The Speechly Command Line Tool provides additional configuration options and allows you to efficiently integrate Speechly to your development workflow.

What is the Command Line Tool and what does it do?

The Command Line Tool (CLI) is a simple program that works in a Unix shell or Windows Terminal. It allows you to create, maintain and deploy Speechly applications on the command line. It provides the same functionalities as the Dashboard, as well as the following additional benefits:

  1. The CLI gives you access to some advanced configuration options (most notably Imports and Lookups) that are not available on the Dashboard.
  2. Using the CLI allows you to use standard tools to maintain Speechly configurations as part of your other development workflow.


The tool is open-source and can be found at our Github repository. For easy installation, we also provide binary releases for macOS, Linux and Windows. Once installed, the tool is invoked by typing speechly.

Select your OS for quick installation instructions.

If you are using MacOS, the easiest way to install is by using Homebrew.
$ brew tap speechly/tap
$ brew install speechly

After tapping, brew updates will include the new versions of speechly.

If you are using Windows, the easiest way to install is by using Scoop.
C:\> scoop bucket add speechly https://github.com/speechly/scoop-bucket
C:\> scoop install speechly

You can update the tool by using scoop update.

For Linux, we provide a pre-compiled x86_64 binary at https://github.com/speechly/cli/releases/latest. The release package contains a README as well as the binary. Just put it anywhere on your PATH and you are good to go.

Of course you can also build the client from source if you need to run this on an exotic architecture.

Adding an API token

After installing the CLI, you must obtain an API token from the Dashboard. Please follow these steps to create an API token:

  1. Log on to the Dashboard.
  2. Click on the project menu in the top right corner (to the left of your user name), and select “Project settings”.
  3. On the page that opens, click on “Create API Token” and give the token a name (this can be whatever).
  4. Click “Show” to see the API Token (It is a long, random string.), and click “Copy” to copy the token to the clipboard.

You have now created an API token for the project that is active on the Dashboard. It provides access to all app_ids within the active project.

Once you have copied the API token to the clipboard, run the command below where <API_Token> has been replaced with your API token. (Simply paste it in your terminal.) You should also specify a name for the project by replacing project_name with something descriptive.

speechly config add --name project_name --apikey <API_Token> --host api.speechly.com

Now you are ready to start using the CLI!

Managing multiple projects

If you have split your applications to multiple projects, you must configure the CLI for each of the projects by following the steps in Adding an API token separately for each project. NOTE: Before selecting “Project settings”, please ensure that you have the correct project currently selected in the Dashboard!

You can see a list of all projects (called “Contexts” in the CLI) that have an API token, as well as the one that is currently active, by invoking

speechly config

The project that is currently active is indicated by “Current config” in the listing.

Switching between projects is done by invoking

speechly config use --name name_of_my_other_project

Basic usage and getting help

This is a brief overview of how the CLI works in general. A reference of the most important commands is at the end of this document.

The CLI follows an approach similar to e.g. git or docker where different functionalities of the tool are accessed by specifying a command followed by arguments to this command. The tool provides usage instructions when invoked without sufficient parameters.

For example, invoking


without other arguments, will print a list of all commands supported by the CLI. Running speechly command will print a brief usage guide for the given command, e.g. typing

speechly create

gives instructions on how to create a new application.

Deploying with the CLI

When deploying a Speechly application with the CLI, the application configuration (SAL templates, Entity Data Types, etc) are defined in a YAML formatted file. This Configuration YAML, together with other configuration files if needed, should all be put in the same directory. The contents of this directory are deployed by invoking

speechly deploy name_of_directory -a deployment_app_id -w

where deployment_app_id should be replaced with the app_id you want to deploy the application to. The -w flag means the Command Line Tool will wait until model training is complete.

Note that the CLI builds and uploads a deployment package that contains all files in the specified directory! It is thus highly recommended to store there only files that are relevant to the configuration. In the simplest case this is only the Configuration YAML.

Configuration YAML

The configuration YAML defines a dictionary of (key, value) pairs that contain definitions both for SAL templates and Entity Data Types as described below. Also, Imports and Lookups are configured within the same Configuration YAML.

Defining SAL templates

Templates are defined with key templates within a “Literal Block Scalar”:

templates: |
  SAL line 1
  SAL line 2

Defining Entity Data Types

Entity Data Types are defined with key entities that has a list of (name, type) pairs as its value:

 - name: entity1_name
   type: entity1_type
 - name: entity2_name
   type: entity2_type

Example configuration YAML

This is a simple example that shows what a complete configuration YAML with entity types and templates looks like:

 - name: product_name
   type: string
 - name: product_amount
   type: number
 - name: delivery_date
   type: date_future
templates: |
  product = [apples | oranges | bananas | grapefruits | mangoes | apricots | peaches]
  amount = [1..99]
  *add_to_cart {add} $amount(product_amount) $product(product_name)
  *set_delivery_date [{schedule} delivery for | delivery on] $SPEECHLY.DATE(delivery_date)  

Suggested workflow

  1. Create a directory for your application’s configuration.
  2. Save files in git or other version control system.
  3. Use speechly deploy in your CI pipeline for deploying the configuration.

Updating the API token

Updating the API token of a project in the command line tool is done by modifying the CLI config file. You can see where the config file is located by invoking

speechly config

The first output line should indicate the “Config file used”. The name of the config file should be .speechly.yaml and it should be located in your home directory. Open this file in a text editor. You should see something like

  host: api.speechly.com
  name: my_project
current-context: my_project

where A_REALLY_LONG_SEEMINGLY_RANDOM_STRING is the current API token of project my_project. If you have several projects, they are all shown separately, each with their own API token.

You can generate a new API token by following steps 1-4 in Adding an API token. (Ensure that you are viewing the appropriate project in the Dashboard before generating the token!) When you have copied the new token, replace A_REALLY_LONG_SEEMINGLY_RANDOM_STRING with the new token, which is just another really long seemingly random string. Save the config file, and the new API token for project my_project is immediately in use.

If you have several projects, you must separately replace the API token for each of these by creating a new token for every project in the Dashboard, and pasting it in the config file.

CLI Reference

The Command Line Tool has a built-in help functionality. This is a brief reference of the most important commands.

List applications

You can print all applications in the currently active project by invoking:

speechly list

Create a new application

A new Speechly app_id is created by invoking

speechly create -l en-US -n name-of-my-app

where you should replace name-of-my-app with a descriptive name of the application. The command will print the newly created app_id.

Deploy a configuration

The simplest way is to enter the directory that contains your configuration files, and run

speechly deploy . -a app-id

where app-id is replaced with the app_id to which you want to deploy the configuration. (Note that app_id must belong to the project that is currently active in the Command Line Tool. See also speechly config.)

See usage statistics

You can view statistics about the usage of your applications by typing

speechly stats

This will print hourly usage statistics for all applications in the current project for the past two weeks. The output shows the total number of utterances, as well as the total amount of received and annotated audio (in secods), respectively.

You can view statistics only of a given application by adding the flag -a APP_ID, where APP_ID is the relevant application id. To adjust the time interval of the results, use the --start-date and --end-date flags. For example

speechly stats -a APPLICATION_ID --start-date 2021-03-01 --end-date 2021-04-01

shows usage statistics for March 2021 (the --end-date value is exclusive) for APPLICATION_ID.

When working on a configuration, it can be very useful to inspect the Example utterances that the templates are expanded to. This way you can spot mistakes and other problems with your configuration.

Enter the directory that contains your configuration files, and run

speechly sample . -a app-id

and again replace app-id with a valid app-id from your current project.

By default the above command returns 100 randomly generated Example utterances from the configuration. If you want to see a larger sample, you can specify the number of Example utterances to generate with the --batch_size (or -s for short) flag:

speechly sample . -a app-id --batch_size 1000

samples 1000 Example utterances.
