Google and AIY Projects have launched an open source DIY artificial intelligence Voice Kit for Raspberry Pi hobbyists. The AIY Voice Kit includes hardware for audio capture and playback, connectors for the dual mike daughterboard and speaker, GPIO pins to connect low-voltage components such as micro servos and sensors, and an optional barrel connector for a dedicated power supply. The Voice Kit can use cloud services such as Google Assistant SDK, which is enabled by default, or it can use the Cloud Speech API or run completely on-device.
