If you want to just simply record your voice over a video rather than using TTS, you can do so by using “Voice Record”.
Step 1: Getting Started
First, have a project opened and ready.
Click on a red microphone icon on the right side of the timeline editor.
Step 2: Record
Adjust the yellow bar on the timeline editor to confirm you are aligned with where you want your voice recording to start.
Next, click record once you are ready to record. You will be given 3 seconds until the actual recording starts.
Step 3: Edit On Timeline Editor
Once the voice recording is created on the timeline editor as an audio block, you can exit out of voice record and edit freely.
