# Age

Evaluates the age of speaker of the input voice.

## Parameters
 none


## Inputs

### Audio
 Accepts audio from a single channel. 


### Events
 none

## Outputs

### Audio
 none

### Events
| name | description |
|---|---|
| [Age Change](/v1/docs/events#age-change)| This event is raised once when the age of the speaker is detected, it will be raised again each time the age of the speaker changes. |

## Remarks  
- This node evaluates the speech in segments of 3 seconds. Silent periods are not included in this duration. 

### Project Structure
The Age Node only needs audio input. The audio doesn't have to be [segmented](/v1/docs/dataflow-nodes-audio-splitters){target=`_blank`}. So, you can place the Age node wherever the desired audio is flowing through. A simple project can be built as such:

</center>

However, a better approach would be:

</center>

:::(Info) (Why this approach is better?)
In the second example, the only difference is that we pass the audio through a VAD node. This means the audio is filtered. The only audio info that passes through a VAD is speech info. This approach will result in better confidence levels in Age identification since random silences are cleared.

### Supported flow types
Stream, Batch
