User Audio Control

Microphone control component with device selection and visualizer

The UserAudioControl component provides a comprehensive microphone control interface that includes microphone toggle functionality, device selection, and optional audio visualization. It integrates with the Pipecat Client SDK to automatically manage microphone state and device selection.

import { UserAudioComponent } from "@pipecat-ai/voice-ui-kit";

<UserAudioComponent
  onClick={() => console.log("Toggle mic")}
  availableMics={[
    {deviceId: "mic1", label: "Built-in Microphone"},
    {deviceId: "mic2", label: "External USB Mic"},
  ]}
  selectedMic={{deviceId: "mic1", label: "Built-in Microphone"}}
  updateMic={(deviceId) => console.log("Selected:", deviceId)}
  isMicEnabled={true}
/>

Component Variants

UserAudioControl

The UserAudioControl component is the connected variant that automatically integrates with the Pipecat Client SDK. It must be used within a PipecatClientProvider context.

You must call initDevices on the client before using the component.

import { UserAudioControl } from "@pipecat-ai/voice-ui-kit";

<UserAudioControl />

UserAudioComponent

The UserAudioComponent is the headless variant that accepts all microphone state and callbacks as props. This allows you to use it with any framework or state management solution.

import { UserAudioComponent } from "@pipecat-ai/voice-ui-kit";

// Example with mock data
const mockMics = [
  { deviceId: "mic1", label: "Built-in Microphone" },
  { deviceId: "mic2", label: "External USB Mic" },
];

function Demo() {
  const [isMicEnabled, setIsMicEnabled] = React.useState(false);
  const [selectedMic, setSelectedMic] = React.useState(mockMics[0]);

  return (
    <UserAudioComponent
      isMicEnabled={isMicEnabled}
      onClick={() => setIsMicEnabled(!isMicEnabled)}
      availableMics={mockMics}
      selectedMic={selectedMic}
      updateMic={(deviceId) => {
        const mic = mockMics.find(m => m.deviceId === deviceId);
        if (mic) setSelectedMic(mic);
      }}
      activeText="Listening"
      inactiveText="Click to start"
    />
  );
}

import { UserAudioControl } from "@pipecat-ai/voice-ui-kit";

<UserAudioControl
  activeText="Listening..."
  inactiveText="Click to speak"
/>

Different Variants

The component supports different visual variants to match your design system.

import { UserAudioControl } from "@pipecat-ai/voice-ui-kit";

<div className="flex gap-4">
  <UserAudioControl variant="primary" />
  <UserAudioControl variant="outline" />
  <UserAudioControl variant="ghost" />
</div>

Different Sizes

You can use different sizes for the microphone control.

import { UserAudioControl } from "@pipecat-ai/voice-ui-kit";

<div className="flex gap-4 items-center">
  <UserAudioControl size="sm" />
  <UserAudioControl size="md" />
  <UserAudioControl size="lg" />
  <UserAudioControl size="xl" />
</div>

Hide the device selection dropdown for a simpler interface.

import { UserAudioControl } from "@pipecat-ai/voice-ui-kit";

<UserAudioControl noDevicePicker />

Hide the audio visualizer for a minimal microphone button.

import { UserAudioControl } from "@pipecat-ai/voice-ui-kit";

<UserAudioControl noVisualizer />

Show a disabled state when audio functionality is not available.

import { UserAudioComponent } from "@pipecat-ai/voice-ui-kit";

function Demo() {
  return (
    <UserAudioComponent
      noAudio={true}
      noAudioText="Microphone not available"
      isMicEnabled={false}
      onClick={() => {}}
    />
  );
}

render(<Demo />);

import { UserAudioControl } from "@pipecat-ai/voice-ui-kit";

<UserAudioControl
  visualizerProps={{
    barCount: 15,
    barGap: 1,
    barMaxHeight: 30,
    barWidth: 2,

Features

  • Microphone Toggle: Click to enable/disable microphone input
  • Device Selection: Built-in dropdown for selecting different microphone devices
  • Audio Visualization: Optional real-time audio level visualization
  • Loading States: Automatic loading indicators during connection setup
  • Accessible: Includes proper ARIA labels and keyboard navigation
  • Responsive: Adapts to different screen sizes and container widths
  • Theme Support: Integrates with the Voice UI Kit theming system

Integration

The connected UserAudioControl component uses several hooks from the Pipecat Client React SDK:

  • usePipecatClientMediaDevices for device management
  • usePipecatClientTransportState for connection state
  • PipecatClientMicToggle for microphone control

This means it must be used within a PipecatClientProvider context to function properly.

The component will automatically:

  • Fetch available microphone devices
  • Display the currently selected microphone
  • Handle device selection changes
  • Manage microphone enable/disable state
  • Show appropriate loading states during connection setup
  • Update the Pipecat Client's microphone configuration

Visual States

The component displays different visual states based on the microphone status:

  • Inactive: Shows microphone off icon with inactive styling
  • Active: Shows microphone on icon with active styling and visualizer
  • Loading: Shows loading spinner during connection setup
  • Disabled: Shows disabled state when audio is not available

Device Management

The component includes a dropdown menu for device selection that:

  • Lists all available microphone devices
  • Shows the currently selected device
  • Allows switching between devices
  • Can be hidden with the noDevicePicker prop
  • Integrates with the DeviceDropDown component
