The default model lang_code is a, which means American English, and it can only use the voice with the prefix a. If you choose a voice with the prefix b (bm_daniel), then launch the model with lang_code='b', e.g.

model_uid = client.launch_model(
    model_name="Kokoro-82M",
    model_type="audio",
    compile=False,
    download_hub="huggingface",
    lang_code="b"
)
