Overdub Voice Quality Tips

Once you’ve created your Overdub voice, here are a few things you can do to ensure a production-ready Overdub voice, with crisp fidelity, realistic intonation, and natural expressiveness.

 

1. Improve your recording conditions.

In case you missed it the first time around: Your training data should be recorded in a quiet, acoustically “dead” room, and you should be using an external microphone.

 

2. Record more training audio.

While Overdub voices can be trained with as little as 10 minutes of audio, we recommend at least 30 minutes. The likelihood of a production-ready voice increases as you increase your training data volume, all the way up to 90 minutes.

Open your training data project to record one of our supplemental scripts.

 

3. Experiment with styles.

Styles let you copy the various delivery styles of your real audio recordings. Every Overdub is generated using a Style; your voice comes loaded with one as a default. The default style might not be optimal for the content you are creating. To create a new Style, select a range of real audio (complete sentences are recommended) that’s three to twenty-five seconds long, right-click, and select “Save as Style.” Learn more about setting up Styles.

 

4. Play with punctuation.

Periods and commas affect Overdub intonation. Add and remove them to fine-tune delivery.

 

5. “Convert to audio” to tweak timing and boundaries.

Right-click on an Overdub (or hover over the clip in the timeline) to convert it to normal Descript audio. Once it’s audio, you can fine-tune the word spacing and sentence boundaries just like any other clip. Learn more about Timeline Editing.

6. Overdub more words.

If you’re making an editorial correction of a word and it sounds unnatural, undo and experiment with grabbing another word or two on either side.

 

7. For pronunciation errors, spell it as it sounds.

If Overdub mispronounces a word, try a different (i.e. incorrect) spelling. Once you’ve got it sounding right, you can always convert the Overdub to audio (see #6).

 

 

8. When writing acronyms, use ALL CAPS.

Acronyms (abbreviated forms of the initial letters of a group of words) can be spelled one of two ways:

  • With periods (N.A.S.A.) - This will pronounce each of the letters individually.
  • Without periods (NASA) - Depending upon the acronym, this may be pronounced ("na-suh") or spelled out (as in NFL - "en-ef-el").
