We build custom voices and design systems for the world's leading brands by blending AI, design, branding and technology.

Voice casting, contracting, voice user experience design, text-to-speech development, performance evaluations and optimizations, and consultancy. We cover every aspect of the text-to-speech process. We assist companies with automation, design, strategy, and optimization to ensure the best possible outcomes.

Many design systems are visually orientated. We’ll enrich and add value by creating a system that includes voice and sound assets, guidelines and strategy to ensure cohesive, consistent and efficient design and development.

A brand is more than just a logo and visual identity. We’ll craft a distinct Voice Brand and Sonic identity, create assets, and establish clear brand guidelines to maintain consistency across all touchpoints through speech. Additionally, we offer services in character and personality design to ensure your brand resonates deeply with your audience, creating a cohesive and engaging brand experience.

Our team of dedicated audio engineers, linguists, voice directors, and producers is committed to achieving excellence in sound and performance. We specialize in producing high-quality speech data and delivering exceptional voice and speech solutions in every language utilizing industry leading technology.

We are known for our data-driven and knowledgable approach and methodologies. We don’t just do things, we leverage perceptual user research and acoustic voice analysis to substantiate or disprove design recommendations. This enables us to make informed decisions and develop successful solutions.

Our specialized and disciplined experts integrate their expertise in voice, strategy, branding, UX design, engineering, and development to enhance your team’s capabilities. Working as one team with our clients, we blend experience, creativity, and AI-driven efficiency to get the best results.


User research, usability testing, acoustic analysis, prototyping, language optimization, speech data production, speech model training, and deployment are just a few of the key components we focus on to help you create a stronger brand and successful voice products and services.

At Voice Branding, the user experience is not just important, it’s our top priority. We are deeply committed to understanding and meeting the needs of our users. Our journey began in Amsterdam as a traditional voice agency, and we quickly expanded our services to digital products and emerging technologies that could automate and optimize user experiences. But our mission goes beyond that. We are passionate about making products and services more inclusive and convenient for all users.

We work on various voice branding projects. We often design Voice Brands and new voices together with design teams. We also do redesign and rebranding projects that update existing assets.

In the past year, we’ve been very busy defining voice branding strategies for global brands and creating custom text-to-speech voices for multiple applications. At Voice Branding, we believe that using the right voice and speaking styles can effectively optimize a user experience and even turn customers into ambassadors. We understand that good design leads to memorable experiences and better conversion rates. That’s why, unlike other voice agencies, we have a team of sound designers, engineers, UX/UI designers, linguists, researchers, and strategists collaborating on projects. This diverse collaboration ensures that every aspect of your voice branding project is expertly handled.
We excel at converting creative energy into practical, result-driven, and delivery-orientated design. There are many capable voice agencies in Europe alone and even more worldwide. Each has a unique workflow.

So, what makes us different from other agencies? Our unique methodological and data-driven way of working. Our craft, engineering skills, and, most importantly, our unwavering commitment to quality. We believe in transparency and flexibility, working closely with our clients to ensure we deliver the best results.

In all facets of the design and strategy process, we are driven by data, feedback, and methodologies specified in context and our client’s unique use cases.

We design simple and smart voice branding assets to represent and amplify your brand. What’s more, our team is not just skilled, but also diverse. We have UX/UI designers, linguists, strategists, audio engineers, and data analysts, all working together to bring a unique perspective to your project. Unlike other traditional design and voice agencies, our design process merges creative design, data analysis, and strategic skills.
Yes, and we certainly will. We’re known to combine superior speech data production with creativity and intelligent solutions to create custom text-to-speech voices.

Our production methods are well thought out and tested. We record and produce speech data while consistently monitoring talent performance to capture pre-defined speaking styles that represent that brand. This is how we create high-quality on-brand speech datasets that we can use to train speech models and deploy APIs.

We maintain close relationships and partnerships with industry-leading text-to-speech companies to ensure that your text-to-speech voice is created using the best AI models available.

We see it as our job to inform and advise you about the pros and cons of various potential speech services we can utilize to get the best possible results. Flexibility and ownership are key. Our clients should be able to change and re-train their speech model whenever a better solution appears in the market.
Yes, we can! At our core, we are a voice branding agency dedicated to the digital and voice-driven era. Our expertise extends beyond just creating custom TTS (Text-to-Speech) voices for companies; we offer a comprehensive approach to branding that includes extensive personality and character design processes.

We believe in creating consistent and efficient designs that resonate with your brand’s identity. Our goal is to help you define and implement effective, sustainable, and cohesive voice branding systems. Whether you need a distinctive voice for your digital presence or a well-rounded character design that embodies your brand’s values, we have the skills and experience to bring your vision to life.
Yes, we do! Our comprehensive suite of services includes performance, evaluation, and optimization tailored to enhance the effectiveness of any voice and language system. Our linguistic experts are dedicated to ensuring your voice applications perform at their best. We fine-tune your voice and language systems to ensure clear, accurate, and natural communication.

We also craft engaging and intuitive dialogues that enhance user interaction and satisfaction. We identify and address interaction errors to improve the overall user experience. And we conduct thorough assessments to ensure your voice systems meet the highest standards of performance and reliability.

With our linguistic services, you can be confident that your voice branding will not only sound great but also perform seamlessly across all interactions.

Our pricing is directly related to the project timeline, deliverables, scope, and team composition. When a project is dynamic and not set in stone, our pricing is based on an hourly rate, where you pay us for the time and materials we spent. Most of our projects have fixed price agreements, which are based on a detailed proposal. 

For example, a typical project with a design agency could take ten weeks and cost €50k to €200k. We will create personalized rates for your project depending on the required team size for the time, deliverables, and engagements. Junior designers are charged €105 per hour, and design executives are paid €195 per hour. We also have discounted pricing for startups. To get a quote, please send us an email.

Yes, yes, yes! We are up for the challenge. We are one of the few agencies that love to enrich and re-design strategies and designs already in place. 

Re-designing is a skill that requires creativity and simplicity without losing the brand’s core identity, assets, and strategies in place—transformation without losing the brand associations you’ve already built.  Over the years, we’ve refined our design methodology, especially for re-design projects. Each re-design project starts with a comprehensive exploration and analysis process to thoroughly immerse ourselves in the brand, its assets, previous strategies, and project data.

Our services range from acoustic analysis and sonic data exploration to UX/UI voice design, prototyping, user testing, complete voice branding, and custom text-to-speech development. 

Our design agency often works side-by-side with in-house design teams or innovative departments, enabling us to work and move fast. We act as an independent entity, avoiding the bureaucracy often associated with large organizations and ensuring efficient and effective project delivery.

Our design philosophy is based on design thinking, which enables us to be adaptable to almost any project and form of collaboration. Although each project is different, we still go through the same main stages:

  • Discovery & research
  • Design prototyping and defining valuable hypothesis.
  • Testing
  • Data analysis
  • Design optimization
  • Developement
  • Quality assessment and evaluation
  • Deployment, guidelines & strategy implementation.

Please email us first with a brief description of your project or an RFI/RFP. We respond within 24 hours to set up an introduction call and to answer any pressing questions.

On our first call, we’ll ask a couple of questions about the project objectives, demographics, budget, timeframe, and other relevant details.

We start with a call to learn as much as possible about the project. Based on this information, we try to estimate the project’s costs as accurately as possible in a proposal that includes a detailed description of the design approach, the project’s stages, deliverables, activities, touch-points, team, and other relevant details.
