Sound Marketing: The Evolution of Sound Branding
What Role Does Voice Play in the Future?
We are living through a global shift in the relationship between people and technology, and sound is at the center of it. Voice commands, virtual assistants, and voice biometrics are already part of everyday life for anyone who uses banking apps, social media, and mobile applications. In this context, sound marketing is no longer an aesthetic detail, it becomes a core brand strategy.
Why Are Voice and Sound Dominating the Relationship Between Brands and People?
Facial recognition is already routine in banking and social media apps, and voice is heading in the same direction. Assistants like Alexa, Siri, and Google Assistant have made voice commands part of everyday consumption, and every sonic response from these systems carries, or should carry, a brand’s personality.
This movement humanizes the relationship between companies and people. The evolution of sound in communication shows how sound moved from radio to jingles and arrived at today’s voice interfaces, playing an increasingly strategic role.
What Is Sound Branding, Exactly?
Sound Branding is the construction of a brand’s sonic identity. The process begins with diagnosis, research, and workshops to identify the sonic attributes that translate a company’s personality into music.
From there, the main sonic brand assets are born: the musical theme, the sound logo, the brand voice, the spoken verbal tone, and the sound design applied to each touchpoint. A world-renowned example is the sound logo from Mastercard, played across millions of transactions in more than 210 countries.
Why Is Creating a Sonic Identity No Longer Enough?
Having music, a sound logo, a brand voice, a verbal tone, and sound design is just the beginning. Without consistent application across all sonic touchpoints, and without processes that maintain that consistency over time, these assets end up shelved and fail to build brand recognition.
This is where the concept of Sound Marketing comes in as a strategic umbrella: it organizes the study, creation, application, and dissemination of a brand’s sound on an ongoing basis, with the support of a specialized Sound Branding consultancy.
It is worth checking out the 6 examples of successful sound branding compiled by Zanna Sound, which show how brands like MetrôRio and Vivo turned sonic identity into business results.
How to Apply a Brand's Sound Across All Touchpoints?
After creation, the work is to teach internal audiences how to handle the brand’s new sonic expression. The company needs to “breathe” the sound before presenting it to external audiences.
Only then does the external launch happen, with team training on how to use the new spoken verbal tone and apply the sonic assets consistently, both internally and externally. The Zanna Sound methodology for Sound Branding and Sound UX details this process, from diagnosis to application across physical and digital touchpoints.
Who Are a Brand's Sonic Ambassadors?
Store salespeople, public transit operators, security agents, executives, and press offices: they all represent the brand and, therefore, also represent its sound. Each of these groups needs to incorporate the verbal tone and sonic assets into their daily contact with customers.
This attention also extends to accessibility. The article Creating Inclusive Sonic Experiences shows how sound marketing can and should include people with hearing impairments in the brand experience.
Is Sound Marketing Only for Large Brands?
No. Startups and growing companies can also build their own sonic identity from day one, with simple and consistent planning, without needing a multinational’s budget.
The article Sonic Branding for Startups explains how defining the right sonic personality from the early stages of a brand prevents rework and builds recognition faster.
What Does Sound Marketing Look Like in 2027?
The future of sound marketing rests on three pillars that complement each other over time. Sound Branding creates the brand’s sonic identity. Sound Production ensures the consistent application of that identity across all touchpoints.
Sound Guardianship is the newest pillar: training, disseminating, launching, and monitoring through research to keep a brand’s sound alive and coherent as years pass, adjusting it as the brand and its audience evolve. This complete journey, from diagnosis to long-term guardianship, is what will set sonic brands apart in 2027 and make them more relevant.
