source

espnet3.demo.ui.build_ui_from_config(ui_cfg) → UiSpec

Build a UiSpec from demo UI configuration.

The configuration is expected to define inputs and/or outputs entries, where each entry includes at least:

• name: logical field name used to build the model input/output dict
• type: component type (e.g., audio, textbox, dropdown)

• Parameters:ui_cfg – UI configuration (typically demo_cfg.ui). Can be an OmegaConf object or any object with inputs/outputs attributes.
• Returns: A typed spec containing instantiated Gradio components and their corresponding names, plus optional metadata (title/description/article).
• Return type:UiSpec
• Raises:ValueError – If a component entry is missing a non-empty name or uses an unsupported type.

Example

>>> spec = build_ui_from_config(ui_cfg)
>>> spec.input_names
['speech']

Notes

• Component instances are created eagerly; this function does not build a full Gradio app by itself.
