How to Enhance Voice in Videos

Voice clarity is important for a lot of videos – whether it's instructions, gameplay, or interviews on any topic. It's always more enjoyable to listen to clear and understandable audio. Viewers can tolerate bad visuals but not bad audio. If you want to enhance voice in video, this guide will help you find out what could be getting in the way, how to reduce noise in Clideo and make your video even more accessible.

What makes a voice hard to hear in a video

Not everyone has good microphones, even though the ones built into modern devices are getting better. In addition, there is the other side to the problem when the microphone is so sensitive that it picks up other noise, or the person is in a slightly noisy place when recording.

Then, how to enhance your voice in a video file? Typically, the easiest way is to remove unwanted noise, especially if everything else sounds fine. There are many apps and programs that can be used to adjust various aspects of the sound and reduce noise levels to fix the issue.

Before editing, listen to a short part where someone is speaking. The words may be difficult to hear for different reasons:

  • Background noise. A fan, wind, or other video sounds can distract from the voice. Noise reduction can help make speech clearer.
  • Low volume. A quiet recording can be difficult to follow even without background noise. If the recording is quiet but otherwise clear, adjusting its volume may be enough.
  • Loud background music. A soundtrack can cover the words even when the voice recording itself sounds fine.
  • Echo or distortion. A voice that sounds distant, harsh, or crackly may need more than noise reduction.
If background noise is the main issue, keep reading to learn how to use Clideo to make a few adjustments and make the voice in your video easier to hear.

  2. Remove background noise from the audio

    After the video is uploaded, it will immediately appear on the timeline. Select it, then in the options tab that appears, open the Audio tab and click the toggle switch to activate the Noise reduction function. Play the video to hear how the voice sounds now.

    Listen to both a quiet part and a part with more background noise. Turn the switch off and on to compare them. The aim is to make the words easier to understand while keeping the voice sounding natural.

    If needed, you can separate the audio track in case you want to edit video and audio separately from each other and apply the fade-in and fade-out effects to the audio.

  3. Check and adjust the sound

    If the voice is too loud, select the video or audio element, open the Audio tab, and lower the volume using the slider. Make a small change, then play the clip again.

    If you have added music on a separate track, select that track and lower its volume until the words are easy to follow.

    Before exporting, play the parts where the voice is quietest or the music is loudest. If possible, also listen through speakers rather than relying only on headphones.

  4. Add subtitles if needed

    Even when the voice sounds clearer, subtitles can help your audience follow the words if they are watching in a noisy place or with the sound turned down. Clideo offers an AI-powered subtitle generation feature in the same tool.

    Click Subtitles in the sidebar and choose Auto subtitles. If the project has several elements with audio, choose the whole project or the clip you want to transcribe. Click Generate to automatically create the subtitles. Automatic generation is available to registered users and uses credits.

    Adding automatic subtitles to a video with speech

    Read through the subtitles, correct any words that were misheard, and check that the timing matches the speech. You can also adjust their style and position so they are easy to read. The subtitles will be part of the exported video. You can also download them as a separate subtitle file. For more details, see our guide to subtitles in Video Editor.

  5. Export and download the result

    After you finish editing, click Export at the top right and pick your preferred output option.

    When the video is exported, you can watch the preview to see how it looks after editing. Listen to the audio as well. If you like the result, click Download to save it back to your device or cloud storage.

Tips for clearer voice recordings and better audio quality

You can actually start enhancing audio before recording the footage to save time later. You don't need a professional studio – first, check the place and equipment you already have.

  • Choose a quieter place. Close a window or move away from a noisy appliance when possible.
  • Check the microphone position. Keep it close enough to pick up your voice clearly, without rubbing against clothes or getting in the way.
  • Listen for room echo. If your voice sounds distant in an empty room, try a different spot with more soft furnishings.
  • Make a short test recording. Speak as you would in the video and listen back before recording the whole thing.

If you are making a voiceover separately, see how to record audio for a video. This also gives you a chance to try another take without filming the scene again.

Frequently asked questions
Is making a voice louder the same as making it clearer?
No. Increasing volume makes the recording louder, including any noise already in it. A clearer voice is one whose words are easier to understand, so the problem may be noise or competing music rather than volume.
Can I improve a voice recording in a video without a separate audio file?
Yes. You can upload the video to Clideo and use its audio settings on the video clip. You don't need to extract the sound into another file before reducing noise.
Does enhancing a voice change its pitch?
Reducing background noise is meant to make the recorded speech easier to hear. It is a different task from changing how high or low the voice sounds.
Why can a voice sound unnatural after noise reduction?
Processing may affect parts of the voice along with the unwanted sound, especially in a difficult recording. Compare the original and processed versions, and keep the one where speech is clearer and more natural.
Can I improve the video audio without recording the video again?
Often, reducing noise and adjusting volume can help. The result depends on the original recording, though. If words are missing or badly distorted, a new voice recording may be a better option. In Clideo, you can record a new voiceover to replace part of the audio or create an AI voiceover from text.
