Audio, calls or recordings, or as we at Voyc call them "Conversations" can be added in two ways:

This article covers how to upload calls via the front end.

Step 1: Navigate to the Conversations tab in the Project and select the "Add Conversations" button: Project > Conversations > Add Conversations.

Step 2: Select the files you would like to upload. You are able to upload multiple files at once. 

Step 3: Complete the audio quality disclaimer.

Note: Check the "Do not show this again" radio button if you would like to skip this step.

Step 4: Select the number of speakers in the conversations then select add.
