• Dolby Voice software platform

    • Now there's no reason to accept poor audio, awkward interactions, and reduced productivity in conferencing — Dolby Voice focuses our legendary audio expertise on business communications to creatively overcome longstanding challenges and dramatically improve the conferencing experience for everyone.

    • Hear the stunning audio quality of Dolby Voice and the Dolby Conference Phone.

    • Dolby Voice benefits

      • Sets a new standard for sound quality

        Superior sound quality delivers lifelike clarity and nuance — while suppressing background noise — for room, mobile, and desktop participants

      • Encourages participation, even from quiet talkers

        Full-room pickup, when used with the Dolby Conference Phone, captures even quiet voices from anywhere in the room, across rooms of all sizes, so everyone can participate effortlessly.

      • Makes conversations easy to follow

        Voice placement presents each speaker's voice from a distinct location, so participants know who's speaking, and can follow what's being said more easily.

      • Delivers proven engineering for modern collaboration

        Unified communications integration across leading video, web, and communications solutions, with flexibility for spaces from huddle rooms to boardrooms, and for IP and PSTN connections.

      • Breakthrough audio for today's work spaces and work styles

        By combining the insights of our scientists and engineers with a relentlessly practical perspective on conferencing needs and infrastructures, we've developed a breakthrough audio solution. Built from the ground up for today's work spaces and work styles, Dolby Voice® gives people in rooms, at their desks, and on their mobile phones impressively clear audio through technology that actively overcomes common conferencing challenges such as background noise, room echoes, and garbled voices.

        Dolby Voice also makes conversation more natural and more productive by enabling everyone to be heard, and by eliminating the delays and cutoffs that frustrate users and discourage participation. And Dolby Voice makes it easier to follow who's speaking and understand what's being said by making it sound as if each person is speaking from a distinct location, the way it sounds when they are together in one room.

        Through all these innovations, and as shown through testing, Dolby Voice drives significantly improved task efficiency through an experience that participants overwhelmingly prefer to traditional conferencing. Hear a real breakthrough in conferencing with Dolby Voice — the difference is as remarkable as it is powerful.

        How to use the Dolby Conference Phone

        The Dolby Conference Phone provides excellent audio across rooms of all sizes, with or without a Dolby Voice enabled service. The Dolby Conference Phone captures even quiet voices from anywhere in the room, across rooms of all sizes, even in challenging acoustic environments. One-touch access makes it an ideal device for joining and managing meetings.

        When used with a Dolby Voice enabled service, the audio is further enhanced with stunning clarity, more natural conversation flow, and voice placement, which presents each speaker's voice from a distinct location to make it easier to follow the conversation.
