# useActiveSpeakerId

> Returns the participant's session_id mentioned in the most recent 'active-speaker-change' event.

`useActiveSpeakerId(params?) : string | null`

Use a `filter` to limit which participants should be considered as active speakers.

## Parameters

<ParamField body="filter" type="Function">
  Callback function to filter which participants should be considered as active speakers by this hook instance. Return `true` to allow the passed `session_id` to become the next active speaker.
</ParamField>

<ParamField body="ignoreLocal" type="boolean">
  If `true`, `useActiveSpeakerId` will ignore when the local participant is the active speaker.
</ParamField>

## Return value

Returns `string | null`. The active speaker's `session_id`. If no participant has unmuted, `useActiveSpeakerId` returns `null`.

## Example

```jsx theme={null}
import { useActiveSpeakerId } from '@daily-co/daily-react';

export const CurrentSpeaker = () => {
  const activeSpeakerId = useActiveSpeakerId();
  return <div>Current speaker id: {activeSpeakerId ?? 'none'}</div>;
};
```
