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

However, a better approach would be:
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 Emotion identification since random silences are cleared.
