-The **Generate audiobooks** TUI form exposes the same per-run controls as these flags: for `audiocpp` the Model picker labels each entry's voice capability (`speaker` / `clone` / `design`), the Voice field is labelled **Built-in voice** on CustomVoice entries and **Voice to clone** everywhere else, Instructions work on every entry (required for `vdes`, optional style/delivery control elsewhere — or the voice itself on families without built-in speakers), a Request options field accepts `KEY=VALUE` items (the `--option` equivalent, shown only for model families whose audio.cpp spec declares request options), and Language overrides the global setting per run (hidden for `faster`, which owns language server-side).
