# Voice strip (Notchset): prompt.md (v2.0.0)

- id: `voice-strip` · version 2.0.0 · block · pro (Pro)
- category: AI interfaces
- build: one set of files for every shadcn style
- install: `npx shadcn@latest add @notchset-pro/voice-strip`
- npm dependencies: lucide-react@^1
- registry dependencies: utils, https://notchset.dev/r/notchset-foundation.json, @notchset/button, @notchset/icon-button, @notchset/orb
- docs: https://notchset.dev/blocks/voice-strip
- The install command carries everything this item needs (files, CSS, tokens, npm and registry dependencies). Prefer it to copying source by hand.

Above the composer while you talk: the live orb (its edge your voice, its body the reply's), what's happening in words that instruct, and the live caption. Mute and End are always there. Captions carry it with the sound off; a refused microphone says how to allow it..

## Build it
- Stack: React 18.3 or 19, TypeScript, Tailwind CSS v4 utility classes on the foundation's roles, a components.json (imports use its aliases).
- Packages: `lucide-react@^1`.
- Files: `components/ui/notchset/blocks/voice-strip.tsx`.
- Registry dependencies, installed with it automatically: shadcn `utils` (cn), `notchset-foundation`, `button`, `icon-button`, `orb`.
- Builds: one set of files, the same for every shadcn style.
- Exports to keep: `VoiceStrip`, and every exported type.
- CSS: the install adds the notchset foundation (its roles, keyframes and motion switch, reading your shadcn tokens for colour) to your global stylesheet once. Nothing to import by hand.
- Re-running `add` (or `--overwrite`) re-applies those rules: put overrides in your own CSS, never in the installed rules.
- Colours: every part reads the foundation's roles (`--ns-canvas`, `--ns-ink`, `--ns-line`, `--ns-signal` …), which read your shadcn tokens (`--background`, `--foreground`, `--border`, `--destructive` …), plus the optional `--success` and `--warning`. Retheme on `:root` or any container; never add Tailwind colour classes inside the component.
- This item reads `--ns-bezel`, `--ns-ink`, `--ns-ink-2`, `--ns-ink-3`, `--ns-radius-xl`, `--ns-raised`, `--ns-selected`, `--ns-text-small`, `--ns-weight-medium`, `--ns-weight-regular`.
- Retune it (on any ancestor) with the foundation's roles and hooks: `--ns-bad`, `--ns-bad-ink`, `--ns-band`, `--ns-band-edge`, `--ns-band-grade`, `--ns-band-optimal`, `--ns-beat`, `--ns-bezel`, `--ns-canvas`, `--ns-cat-1`, `--ns-cat-2`, `--ns-cat-3`, `--ns-cat-4`, `--ns-cat-5`, `--ns-cat-6`, `--ns-check`, `--ns-chip`, `--ns-control`, `--ns-control-pad`, `--ns-control-sm`, `--ns-deep`, `--ns-deep-ink`, `--ns-deep-ink-2`, `--ns-deep-line`, `--ns-dialog`, `--ns-dialog-lg`, `--ns-dialog-sm`, `--ns-ease`, `--ns-ease-in`, `--ns-ease-panel`, `--ns-ease-pop`, `--ns-field`, `--ns-flood-arc`, `--ns-flood-aurora`, `--ns-flood-behind-1`, `--ns-flood-behind-2`, `--ns-flood-bloom`, `--ns-flood-deep`, `--ns-flood-dial-bloom`, `--ns-flood-glass`, `--ns-flood-grain`, `--ns-flood-image`, `--ns-flood-ink`, `--ns-flood-ink-low`, `--ns-flood-light`, `--ns-flood-mid`, `--ns-flood-pale`, `--ns-flood-pane`, `--ns-flood-pane-edge`, `--ns-flood-pill-ink`, `--ns-flood-ribbon`, `--ns-flood-ribbon-core`, `--ns-flood-shadow`, `--ns-flood-sheen`, `--ns-flood-wash`, `--ns-font-body`, `--ns-font-display`, `--ns-font-mono`, `--ns-font-script`, `--ns-glass`, `--ns-glass-blur`, `--ns-glass-shadow`, `--ns-glow`, `--ns-grain`, `--ns-gutter`, `--ns-header`, `--ns-heat`, `--ns-hover`, `--ns-ink`, `--ns-ink-2`, `--ns-ink-3`, `--ns-ink-4`, `--ns-leading`, `--ns-lift`, `--ns-light-1`, `--ns-light-2`, `--ns-light-3`, `--ns-light-spread`, `--ns-light-strength`, `--ns-line`, `--ns-line-soft`, `--ns-lit-edge`, `--ns-menu-dy`, `--ns-menu-row`, `--ns-mesh`, `--ns-mesh-frost`, `--ns-ok`, `--ns-ok-ink`, `--ns-orb-body`, `--ns-orb-cool`, `--ns-orb-core`, `--ns-orb-dawn`, `--ns-orb-deep`, `--ns-orb-edge`, `--ns-orb-grain`, `--ns-orb-ground`, `--ns-orb-halo`, `--ns-orb-inner`, `--ns-orb-key`, `--ns-orb-lift`, `--ns-orb-limb`, `--ns-orb-limb-from`, `--ns-orb-rim`, `--ns-orb-skin-hi`, `--ns-orb-skin-lo`, `--ns-orb-skin-mid`, `--ns-orb-warm`, `--ns-panel`, `--ns-panel-w`, `--ns-prism-edge`, `--ns-prism-glint`, `--ns-prism-sheen`, `--ns-prism-tint`, `--ns-pulse`, `--ns-radius`, `--ns-radius-card`, `--ns-radius-full`, `--ns-radius-lg`, `--ns-radius-sm`, `--ns-radius-xl`, `--ns-raised`, `--ns-range`, `--ns-row`, `--ns-row-compact`, `--ns-segment`, `--ns-selected`, `--ns-series`, `--ns-series-core`, `--ns-series-lilac`, `--ns-series-tint`, `--ns-shadow-dialog`, `--ns-shadow-float`, `--ns-shadow-panel`, `--ns-sheet`, `--ns-sheet-bottom`, `--ns-side`, `--ns-signal`, `--ns-sleep-awake`, `--ns-sleep-deep`, `--ns-sleep-light`, `--ns-sleep-rem`, `--ns-space-1`, `--ns-space-2`, `--ns-space-3`, `--ns-space-4`, `--ns-space-5`, `--ns-space-6`, `--ns-space-8`, `--ns-space-section`, `--ns-stack-on`, `--ns-standing-critical`, `--ns-standing-in`, `--ns-standing-out`, `--ns-state-doing`, `--ns-state-done`, `--ns-state-review`, `--ns-state-todo`, `--ns-switch-h`, `--ns-switch-w`, `--ns-text-body`, `--ns-text-control`, `--ns-text-display`, `--ns-text-figure`, `--ns-text-headline`, `--ns-text-hero`, `--ns-text-lede`, `--ns-text-meta`, `--ns-text-page`, `--ns-text-record`, `--ns-text-small`, `--ns-text-strong`, `--ns-text-sub`, `--ns-text-title`, `--ns-tile-shadow`, `--ns-time-born`, `--ns-time-color`, `--ns-time-dialog`, `--ns-time-menu`, `--ns-time-page`, `--ns-time-panel`, `--ns-time-toast`, `--ns-tint`, `--ns-tint-ink`, `--ns-toast-bottom`, `--ns-toast-left`, `--ns-touch`, `--ns-tracking-display`, `--ns-tracking-headline`, `--ns-warn`, `--ns-warn-ink`, `--ns-wash-clay`, `--ns-wash-dusk`, `--ns-wash-graphite`, `--ns-wash-ink`, `--ns-wash-sage`, `--ns-wash-sand`, `--ns-weight-light`, `--ns-weight-medium`, `--ns-weight-regular`, `--ns-weight-strong`, `--ns-well`.
- Never add Tailwind colour classes inside the component.

```tsx
import { VoiceStrip, type VoiceState } from "@/components/ui/notchset/blocks/voice-strip";
```

## Parts
- A single export that takes props.

## Match the original
- Read `components/ui/notchset/blocks/voice-strip.tsx` as the reference implementation before changing or recreating anything, and match it: sizes, colours per theme, motion timings, copy and behaviour.
- If you deviate (a prop you can't honour, a style you changed, a dependency you swapped), say so in your reply, part by part.
- Keep the accessibility contract, the keyboard map and the motion levels listed below.

## Use it when

### Not when

## Built from
- button (`button`), installed with it: reuse it, don't rebuild it
- icon-button (`icon-button`), installed with it: reuse it, don't rebuild it
- orb (`orb`), installed with it: reuse it, don't rebuild it

## Mistakes
- Recreating the component instead of installing it

## Usage

```tsx
"use client";
import * as React from "react";
import { VoiceStrip, type VoiceState } from "@/components/ui/notchset/blocks/voice-strip";
import { Button } from "@/components/ui/notchset/button";

/* a sample conversation, played as captions (no sound): the template's voice adapter drives the real one */
const SCRIPT: { state: VoiceState; caption?: string; speaker?: "you" | "assistant"; ms: number }[] = [
  { state: "connecting", ms: 900 },
  { state: "listening", caption: "When does the launch email go out?", speaker: "you", ms: 2400 },
  { state: "thinking", ms: 1400 },
  { state: "speaking", caption: "Tuesday at 9 am, to the three people on the beta list.", speaker: "assistant", ms: 3200 },
  { state: "listening", ms: 2000 },
];

export default function VoiceStripDemo() {
  const [i, setI] = React.useState(0);
  const [muted, setMuted] = React.useState(false);
  const [ended, setEnded] = React.useState(false);
  const [level, setLevel] = React.useState(0);
  const step = SCRIPT[i]!;
  React.useEffect(() => {
    if (ended || muted) return;
    const t = setTimeout(() => setI((n) => (n + 1) % SCRIPT.length), step.ms);
    return () => clearTimeout(t);
  }, [i, ended, muted, step.ms]);
  const voiced = !ended && !muted && (step.state === "listening" || step.state === "speaking");
  /* a stand-in for the voice level, so the orb's edge and body have something to follow */
  React.useEffect(() => {
    if (!voiced) return;
    const t = setInterval(() => setLevel(0.25 + Math.abs(Math.sin(Date.now() / 160)) * 0.6), 90);
    return () => clearInterval(t);
  }, [voiced]);
  if (ended)
    return (
      <div className="flex items-center gap-3 text-[length:var(--ns-text-small)] text-[var(--ns-ink-2)]">
        Voice ended. What was said is in the thread.
        <Button size="sm" onClick={() => (setEnded(false), setI(0))}>
          Talk again
        </Button>
      </div>
    );
  return (
    <VoiceStrip
      className="max-w-[640px]"
      state={muted ? "muted" : step.state}
      input={voiced && step.state === "listening" ? level : 0}
      output={voiced && step.state === "speaking" ? level : 0}
      caption={muted ? undefined : step.caption}
      speaker={step.speaker}
      soundOff
      onMute={() => setMuted(!muted)}
      onEnd={() => setEnded(true)}
    />
  );
}
```

## Customising
- Colours: every part reads the foundation's roles (`--ns-canvas`, `--ns-ink`, `--ns-line`, `--ns-signal` …), which read your shadcn tokens (`--background`, `--foreground`, `--border`, `--destructive` …), plus the optional `--success` and `--warning`. Retheme on `:root` or any container; never add Tailwind colour classes inside the component.
- Dark mode follows the `.dark` class or `data-theme="dark"` on an ancestor (the shadcn and next-themes conventions).
- Update later: Commit or stash local changes first (or copy the files), so the update can be undone. Read https://notchset.dev/r/changelog.json for the new versions: a major version, an entry marked breaking or a merge says what to change. Then re-run the install with `--overwrite`, on a branch. It replaces the component's files, the shared helper files they import, and the item's CSS rules in the global stylesheet, so review the whole diff (components, shared files, CSS), re-apply your own edits, and run the app's typecheck, tests and build.

## Accessibility contract (preserve when editing)

## Install

```bash
npx shadcn@latest add @notchset-pro/voice-strip
```

Pro item: needs the `@notchset-pro` registry in `components.json` and `NOTCHSET_TOKEN` in `.env.local` (https://notchset.dev/account). Setup: https://notchset.dev/docs/pro. Every components.json `style` gets the same files.

The foundation (the tokens listed above, keyframes and motion levels) installs once with the first component; its CSS is public at https://notchset.dev/r/notchset-foundation.json.
