Easy to Implement

Dolby Voice is a software solution that runs on industry-standard hardware, with open APIs for integration into existing service-provider architectures. The soft-client subsystem supports Microsoft® Windows®, Mac OS®, iOS, and Android™ operating systems, and it can also be easily integrated into the broader conferencing client.

Dolby Voice technology works well in unmanaged network environments over the public Internet, without a specific quality of service configuration.

The Dolby Voice conferencing system gives service providers higher performance, richer impairment monitoring, and seamless integration.

Sound Business Sense

Businesses that use services powered by Dolby Voice will see an increased ROI for their collaboration tools. Meetings will be more effective due to improved communication, with greater efficiency, accuracy, and clarity. Effective and natural communications speed up business processes. When online business conferences actually live up to their promise, travel expenses will go down.

With Dolby Voice, people can focus on the conversation, not the connection.

In addition to our DVC-2 wideband codec, Dolby Voice reduces noise, matches volume levels, and adapts to network impairments. Dolby Voice is also the only solution on the market today that can, at service-provider scale, create a unique spatial audio scene for each Dolby Voice Client participant.

This unlocks the power of the human brain to understand what is being said, even when people are talking over each other (often referred to as the cocktail party effect). The Dolby Voice spatial audio scene enables each user to "tune in" to individual voices.
