Note: I do not own the copyright for Rocky voice and I do not encourage cloning artists' voices for commercial purposes. This is just for a fun personal DIY project intended for the fan community!

Last week I shared my Rocky build here and the support was incredible! Fist my bump to all of you! :)

I received a couple comments on YouTube asking if I could make Rocky actually talk instead of just displaying text. One comment suggested using Qwen voice cloner paired with a Piper TTS workflow. I spent the last few days diving into that, and here is how I got it working:

I took a short, clean sample of the Rocky voice and used Qwen3 TTS to clone the profile. Then I used that clone to generate 500 random phrases. I used those 500 audio clips as input to train a custom Piper model.

The demo video is running the model directly on the Raspberry Pi with Piper TTS.…
