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.

### Installation
|
|
|
|
The Snips Voice Platform is installed on Raspberry Pi with the following command:
|
|
|
|
```sh
|
|
(pi) $ curl https://install.snips.ai -sSf | sh
|
|
```
|
|
|
|
### Creating an assistant

|
|
</div>
|
|
|
|
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
|
|
$ scp assistantproj_XXX.zip pi@pi_hostname:/home/pi/assistant.zip
|
|
```
|
|
|
|
and installed locally via the `snips-install-assistant` helper script:
|
|
|
|
```sh
|
|
(pi) $ sudo snips-install-assistant assistant.zip
|
|
```
|
|
|
|
### 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:
|
|
|
|
```sh
|
|
(pi) $ snips
|
|
```
|
|
|
|
Snips is now ready to take voice commands from the microphone. To trigger the listening, simply say
|
|
|
|
> Hey Snips
|
|
|
|
followed by a command, e.g.
|
|
|
|
> Set the lights to green in the living room
|
|
|
|
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/nlu/intentParsed` 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.
|
|
|
|
## Home Assistant configuration
|
|
|
|
By default, the Snips MQTT broker runs on port 9898. We should tell Home Assistant to use this as a broker, rather than its own, by adding the following section to `configuration.yaml`:
|
|
|
|
```yaml
|
|
mqtt:
|
|
broker: 127.0.0.1
|
|
port: 9898
|
|
```
|
|
|
|
In Home Assistant, we trigger actions based on intents produced by Snips. This is done in `configuration.yaml`. For instance, the following block handles `ActivateLightColors` intents (included in the Snips IoT intent bundle) to change light colors:
|
|
|
|
```yaml
|
|
snips:
|
|
intents:
|
|
ActivateLightColor:
|
|
action:
|
|
- service: light.turn_on
|
|
data_template:
|
|
entity_id: light.{% raw %}{{ objectLocation | replace(" ","_") }}{% endraw %}
|
|
color_name: {% raw %}{{ objectColor }}{% endraw %}
|
|
```
