The [Snips Voice Platform](https://www.snips.ai) allows users to add powerful voice assistants to their Raspberry Pi devices without compromising on Privacy. It runs 100% on-device, and does not require an Internet connection. It features Hotword Detection, Automatic Speech Recognition (ASR), Natural Language Understanding (NLU) and Dialog Management.

Snips takes voice or text as input, and produces *intents* as output, which are explicit representations of an intention behind an utterance, and which can subsequently be used by Home Assistant to perform appropriate actions.

Snips assistants are created via the [Snips Console](https://console.snips.ai). Once trained, the assistant should be downloaded and copied to the Raspberry Pi:
```sh
```bash
$ scp assistantproj_XXX.zip pi@pi_hostname:/home/pi/assistant.zip

and installed locally via the `snips-install-assistant` helper script:
```sh
```bash
(pi) $ sudo snips-install-assistant assistant.zip

### Running Snips
### {% linkable_title Running Snips %}
Make sure that a microphone is plugged to the Raspberry Pi. If you are having trouble setting up audio, we have written a guide on [Raspberry Pi Audio Configuration](https://github.com/snipsco/snips-platform-documentation/wiki/1.-Setup-the-Snips-Voice-Platform-on-your-Raspberry-Pi#configuring-the-audio).
Start the Snips Voice Platform using the `snips` command:
Raspberry Pi:
```sh
```bash
(pi) $ snips
```
Debian/Ubuntu:
```sh
sudo systemctl start "snips-*"

We should see the transcribed phrase in the logs, as well as a properly parsed intent. The intent is published on MQTT, on the `hermes/intent/<slotName>` topic. The Snips Home Assistant component subscribes to this topic, and handles the intent according to the rules defined in `configuration.yaml`, as explained below.
#### Optional: specifying an external MQTT broker
#### {% linkable_title Optional: specifying an external MQTT broker %}
By default, Snips runs its own MQTT broker. But we can also tell Snips to use an external broker by specifying this when launching Snips. In this case, instead of running the `snips` command above (which assumes we are using the internal MQTT broker), we use the full launch command with explicitly specified parameters (replace `MQTT_BROKER_IP` and `MQTT_BROKER_PORT` with appropriate values):
Raspberry Pi:
```sh
$ docker run -t --rm --name snips --log-driver none -v /home/pi/.asoundrc:/root/.asoundrc -v /opt/snips/config:/opt/snips/config --privileged -v /dev/snd:/dev/snd snipsdocker/platform --mqtt MQTT_BROKER_IP:MQTT_BROKER_PORT

### Triggering actions
### {% linkable_title Triggering actions %}
In Home Assistant, we trigger actions based on intents produced by Snips using the [`intent_script`](/components/intent_script) component. For instance, the following block handles `ActivateLightColors` intents (included in the Snips IoT intent bundle) to change light colors:
