Which offline voices should Gotchi Local ship next?

Today Gotchi Local can download Whisper.cpp for transcription and a Piper voice for speech, both from Hugging Face, as offline fallbacks for when it is not using the FrontierOS backend.

Kokoro and Pocket TTS look like strong candidates for more natural offline voices on a laptop host. Which would you want, and in which languages?
