Adafruit Teases the Voice Bonnet Raspberry Pi Add-On with a Homebrew Google Assistant Demo
Short demo showcases the speaker, microphones, button, LED, and STEMMA QT connectors by hooking up an OLED panel.
Adafruit has teased a project built around its upcoming Voice Bonnet add-on for the Raspberry Pi, demonstrating how to turn the single-board computer into a Google Assistant system.
"This Voice Bonnet adds stereo speaker output, stereo microphone, a button, RGB LEDs and an I2C port," Ladyada explains of the upcoming add-on in a brief teaser video. "The STEMMA QT connector means I can add things like an OLED display so when I ask the Google Assistant something it'll actually print out what it thinks I'm saying. It's kind of a cool way to add more accessibility to voice assistants. [The Voice Bonnet is] kind of a mini version of our BrainCraft HAT."
The brief teaser uses the Voice Bonnet, connected to a Mini Black HAT Hack3r breakout which is in turn connected to a Raspberry Pi host, as a microphone and speaker for the Python-based Google Assistant demonstration script. The STEMMA QT connector is used to connect the Voice Bonnet to an OLED display, which is controlled via the Blinka library to print out both the recognised text and the response.
Adafruit has not yet offered a release or pricing for the Voice Bonnet, but has already launched the bigger BrainCraft HAT at with on-board color display at $39.95.
