Not long ago, when creating a vlog, reel, or TikTok video, the most important decision was which music to choose: a currently viral song, a forgotten hit, or a funny sound that matched what was on screen. Narration, especially audio narration, was rare. Creators would often even apologize for using voice-over because they didn’t like the sound of their own voice. Recently, however, we’re witnessing a major shift: brands and creators are equipping themselves with professional audio gear, and voice-overs have become planned, flawlessly executed, and at times even poetic. Why is that?
The Power of Voice: Why Voice-Over Works
The most obvious answer is that it’s much easier, deeper, and faster to emotionally connect with a human voice than with text or visuals alone. Using voice adds a human element to the brand or creator and enhances message comprehension. This is why voice-overs have been a staple in advertising since its earliest days.
In recent years, we’ve seen the rise of podcasts and the growing use of voice messages. Whether it’s due to visual fatigue or a general sense of societal loneliness, it seems we enjoy listening to other people’s voices. Podcasts and vlogs are essentially storytelling tools, and storytelling is an incredibly valuable asset for brands. It’s no surprise, then, that we’re seeing (or rather, hearing ????) more voice-over use in educational videos, brand explainers, and product demonstrations.
Sound as Brand Identity
While the importance of visual identity for brands is well-known, what about sound? Sonic branding isn’t new, but with the growing use of audio and voice-over in digital marketing, it’s becoming more significant. We used to associate audio logos mainly with film production companies (like Warner Bros.’ jingle or MGM’s lion roar), but today, some of the most recognizable include McDonald’s whistle or Netflix’s “ta-dum.”
Brands are embracing audio logos because consistent sound builds recognition. Some even develop a complete audio identity—using a signature music style, tone of voice, diction, and even vocal timbre.
Platforms that Prioritize Sound
Social media platforms like TikTok, Instagram Reels, and YouTube Shorts rely on short video formats where sound is essential for visibility and engagement. In these contexts, a well-executed voice-over can enhance the message, grab attention, or heighten emotional impact.
Podcasts are another increasingly popular platform for brands. With well-produced episodes, they can build authority, trust, and loyalty. Voice-over becomes a tool for structuring episodes—used in introductions, branded segments, or ad messages—where professional tone and delivery are key.
Voice assistants like Alexa, Google Assistant, and Siri are also rising in relevance. Brands that develop apps and content optimized for voice search have the chance to be present in a completely new kind of interaction—one that happens without a screen.
On all of these channels, where sound is the primary mode of communication, voice-over can be the difference between an average and an outstanding user experience.
