Voice Input
The microphone button in a composer, which becomes a pill with the last second of your level as bars, an mm:ss timer, Stop to keep and Cancel to throw away. It records on its own, or you drive it from your own audio pipeline.
The decision inside it
Denied is a state, with words
When the browser refuses the microphone it says so and says where to allow it. A mic button that silently does nothing after a refused prompt is the most common voice bug, and it reads as broken rather than blocked.
When to use it
Use Voice Input for dictation in a chat composer. Left alone it asks for the microphone, shows the level and hands you the recording as a Blob on stop. If your realtime voice API already owns the microphone, pass state and level and it only draws.
Installation
How you get it
Paste this into Claude Code, Cursor, Codex or any coding agent. It installs the file and uses it as it is, instead of writing a new one.
Use Layro's Voice Input for this.
Install it: npx shadcn@latest add @layro/voice-input
(the @layro registry is set up in components.json, with LAYRO_KEY in .env.local)
Import it from @/components/ui/voice-input.
Do not rewrite or restyle it. Pass my data through its props
and keep its built-in states.For the full brief with every prop and the mistakes assistants usually make, use Copy prompt above. Pro components install through the @layro registry with your CLI token: see the Namespaced tab.
Usage
import { VoiceInput } from "@/components/ui/voice-input";
export function ComposerVoice({ transcribe }: { transcribe: (audio: Blob) => void }) {
return (
<VoiceInput
size="sm"
maxDuration={120}
onStop={(blob) => blob && transcribe(blob)}
onCancel={() => console.info("discarded")}
/>
);

Props
Read from the component’s own TypeScript interface when the site is built, so this table cannot drift from the file you install.
| Prop | Type | Notes |
|---|---|---|
state | VoiceState | Drive the state yourself. Leave out and the component records on its own. |
level | number | Audio level 0–1, when you drive the state. Ignored while the built-in microphone runs. |
useMicrophone | boolean | Use the built-in getUserMedia, analyser and MediaRecorder. Default true when `state` is not passed. |
maxDuration | number | Stop on its own after this many seconds. |
onStart | () => void | Called when recording starts (or, when you drive it, when the mic button is pressed). |
onStop | (blob: Blob | null, durationMs: number) => void | Called with the recording and its length. The Blob is null when you drive the state. |
onCancel | () => void | Called when the recording is thrown away (Cancel or Escape). |
transcript | string | A live partial transcript, shown beside the bars while recording. |
size | "sm" | "md" | sm fits inside a composer row; md stands alone. Default md. |
errorMessage | string | Shown in the error state. |
