+
+Home Assistant Voice relies on different technologies, models, and data sources to process wake words and commands in all languages. Our and other communities' projects rely on volunteers who donate their time, voice, or language knowledge to improve.
+
+Note that models are trained on lots of data and that it can take time before you are able to see the impact of your contributions.
+
+### Contribute samples to Wake Word Collective
+
+Give us a minute of your time to improve the sample database [with your own samples](https://ohf-voice.github.io/wake-word-collective/).  
+
+### Donate your voice to Piper
+
+To create a Piper voice, you don't need an army of volunteers. You need a native speaker of a language to create a dataset, which is then trained into a Piper model and verified again by the native speaker.[Check the Training guide](https://github.com/rhasspy/piper/blob/master/TRAINING.md).
+
+Are you missing a language? Email us if you want to help out! To help interested people contribute languages, we opened up the email address [voice@nabucasa.com](mailto:voice@nabucasa.com).
+
+### Other ways to contribute with intents and samples
+
+You can also participate in public datasets. Commonvoice and Librivox are used by many speech-to-text projects to train their models.
+
+- [Contribute samples to Mozilla Commonvoice](https://commonvoice.mozilla.org/en)
+- [Contribute samples to Librivox](https://librivox.org/)
+
+### Become an active contributor
+
+There are also a couple ways to actively contribute to the development of the voice initiative:
+- [Contribute sentence intents in your language](https://developers.home-assistant.io/docs/voice/intent-recognition/contributing/)
+- [Become a language leader](https://developers.home-assistant.io/docs/voice/language-leaders)
+- [Contribute code to Assist](https://github.com/home-assistant/core/tree/dev/homeassistant/components/assist_pipeline)
