When using Aha Radio streaming service, a "shout" is essentially a post or short voice memo to Aha channel that allows this option:

From Aha website-->Within some stations users have the ability to record short audio messages, called SHOUTS. How these SHOUTS are used can vary by station type.

Facebook – Recording a SHOUT within your Facebook station will post a playable audio file on your Facebook wall. This will also appear in your friends’ News Feeds.

Traffic – SHOUTS recorded in Traffic will automatically show up to other drivers who are on the same road as you. It’s a quick and easy way to let others on the road know about possible slowdowns or accidents, so they can plan accordingly.

We have two options (terminology conflict) in Russian as follows:

1. Голосовая заметка
2. Восклицание

Which one is best?
