Thanks @hannahblair! Dark mode looks good but the text is still invisible in light mode:

import gradio as gr

with gr.Blocks(title="Audio Generation", theme=gr.themes.Monochrome()) as demo:
    input = gr.Textbox(label="需要转换的文本", value="最近很辛苦，五一我要出去找个地方散散心！")
    output = gr.Audio(label="合成的语音")
    gr.Examples(
        examples=[["cantina.wav", "abc"]]*4,
        inputs=[output, input],
    )

demo.launch()
