Since 2017, we have been working with Swisscom to continuously develop Brand and Service’s audio communication—from service experience, Sonic Code, and campaign-based applications to a scalable management system for AI voices and audio/voice content.
Today, the focus is on the centralized management of audio and voice content. AI voices, multilingual capabilities, operational processes, and tools are systematically integrated, thereby sustainably enhancing consistency, clarity, efficiency, and the customer experience.
Project Outline
Challenge
Swisscom wanted to design service dialogues that were consistent, multilingual, and aligned with the brand. At the same time, audio communication across numerous service lines needed to be centrally controllable, efficiently manageable, and usable for operational deployment with AI voices.
Methodology
comevis collaborated with Swisscom to develop a scalable management system for AI-powered audio communication. At the heart of the system is the AI Voice Media Manager, which enables audio and voice content to be centrally controlled, created, managed, and integrated into the service environment. The central AI Voice was developed jointly with Swisscom during a workshop using comevis’s AI Voice Lab software.
Result
The result is a scalable setup that systematically integrates the development, management, and deployment of AI Voices. In this way, the system creates consistent dialogues across numerous service lines and languages, thereby enhancing a unified customer experience.
Strong Connections. Strong Partners.
As a long-standing partner of Swisscom, we are pleased to support its continued success—achievements that are reflected, among other things, in its numerous top rankings in connect tests.
Sound of Collaboration
“We want to provide our customers with better auditive guidance and create a positive experience in every way. By systematically combining conversational AI and audio branding, we were able to create a scalable, brand-aligned conversational experience with comevis that audibly differentiates our brand and deepens customer loyalty. Seasonal and event-related adjustments—such as those for the World Cup—can be flexibly integrated and support our commitment to delivering a tangible service experience.”

Implementation
Strategy
The starting point was the question of how voice could do more than just serve as a mere function in digital services. This became apparent early on with the Swisscom Box and its voice assistant: voice became the direct interface for the customer experience. The AI Voice Lab then developed the central AI Voice SAM—tailored to the brand and persona to ensure a consistent voice experience.
Transformation
Individual audio and voice applications such as Sonic Code, Service Experience, and campaigns have evolved into a scalable system for audio communication. Today, AI Voices enhance the customer experience and make communication clear, consistent, and recognizable across different languages and touchpoints.
Empowerment
With the AI Voice Media Manager, Swisscom has a central platform for controlling, managing, and integrating audio and voice content directly into its service environment. This enables the efficient management of AI voices, multilingual capabilities, and operational processes, ensuring a consistent customer experience.

Swisscom
AI Voices
Several AI Voices were developed for Swisscom, each specifically tailored to different service and dialogue requirements.
Instead of a single voice, a system of clearly defined voice roles was created that structures digital interactions, ensures recognizability, and makes the brand audible across various touchpoints.
In this way, the AI Voices combine efficient service communication with a consistent, brand-aligned customer experience.
Swisscom's digital colleagues
SAM
SAM is Swisscom’s central AI voice and serves as the direct point of contact in service and customer interactions. She represents the brand audibly and lends a consistent personality to communications with her clear, precise, and helpful manner.
COMPANION
Companion is designed to serve as a supportive voice for service and dialogue. It guides users through interactions with a calm, reassuring tone and provides clear explanations in a pleasant conversational atmosphere.
GUIDE
Guide is the male voice in the system, designed to provide guidance, context, and clear explanations. As a reliable partner for complex topics, it delivers information in a structured manner and confidently guides users through service processes.
Swisscom Interaction Flow
Language variations
Responsive loading indicator
In the interactive hold screen, callers can actively shape their waiting experience. Instead of a static hold loop, they can choose from a variety of audio options—including a jukebox, soothing and relaxing music, and Swisscom Music.
This not only makes waiting times more pleasant, but also actively integrates them into the customer experience. The responsive waiting interface provides greater control over the service experience, enhances the perceived quality of service, and turns even waiting times into a manageable part of audio communication.

Swisscom’s audio communication also demonstrates its flexibility in seasonal and event-specific scenarios. Whether it’s Christmas, point-of-sale situations, or major events like the World Cup, content is tailored specifically for service calls, adding extra relevance to customer interactions.
This creates context-specific service experiences that remain consistent with the brand and elevate the customer experience beyond the norm.

Media Manager
The AI Voice Media Manager is a software environment developed by comevis for the centralized management of audio and voice content.
At Swisscom, the system is used for the service lines. The three AI voices enable the production of voice content in four languages and are available in nine specific variants.
An integrated media library with advanced search functionality ensures that audio assets can be quickly located, even based on their spoken content.
With the built-in VADio Creator Pro, you can create audio and voice content directly. The Conversational Designer helps you improve dialogue text in a use-case-oriented manner.
Through the integration with Genesys, content can be deployed directly into the service environment.
To protect sensitive information, content from the tool was not displayed.

AI Voice Development
The AI Voice Lab is a software solution from comevis designed to develop brand-specific AI voices. Voices are not generated randomly, but are carefully crafted to align with the brand and persona until a suitable voice profile is created.
A self-learning AI supports this process by deriving new voice variations from each classification. In this way, the profile is refined with each iteration and moves closer to the target.
For Swisscom, the AI Voice Lab was implemented on-site through a joint workshop with representatives from marketing, customer service, brand operations, and IT. This initiative resulted in the creation of SAM, the central voice that is now used in customer service and interactive contexts.
Swisscom
Creator Audio Voice
With VADio Creator Pro, creating audio and voice content becomes even more flexible, precise, and collaborative.
Custom voice content can be intuitively generated via text or voice input and automatically converted into premium-quality AI voices. Automated quality checks, centralized project management, and structured asset handling ensure that audio outputs can be produced efficiently, consistently, and across all touchpoints.
At Swisscom, VADio Creator Pro is integrated into the AI Voice Media Manager, where it is used for audio and voice content in services and interactive applications. The tool is also available as a standalone solution and is used at events and in video production to add voiceovers to content.

Swisscom Sonic Code
The Sonic Code systematically embeds Swisscom’s auditiveidentity into digital services and interactions.
Multilingual, brand-consistent voices are an integral part of this system and ensure consistency across all service and dialogue contexts.
