Story voices are synthesized offline with Kokoro-82M. Ethan uses the native Bella female voice, with no pitch shifting. The English narrator uses Heart; Papa and Uncle Cow use Michael. Mandarin voices are synthesized offline with CosyVoice 3 (Fun-CosyVoice3-0.5B-2512). The female storyteller uses the official repository example voice, as heard in the five-page comparison. Male and Ethan voices use the previously approved synthetic Kokoro voices as references for new CosyVoice recordings. No pitch shifting is applied.
