BT, Dolby transform conference calls so you feel like you're in the room

BT and Dolby Laboratories today announced the launch of BT MeetMe with Dolby Voice, an audio conferencing service that can dramatically transform one of business's most essential, but problem-plagued daily activities - the conference call - by replicating the sound of face-to-face meetings.

BT MeetMe with Dolby Voice features a natural audio quality that makes remote conference call participants feel as if they are in the same room, enabling them to focus on the content of the conversation, without being distracted or frustrated by the limitations of standard conference call technology.

This improves understanding and productivity, allowing decisions to be made more quickly, saving time and money.

BT MeetMe with Dolby Voice, exclusive to BT, offers:

* High fidelity audio - gives outstanding sound clarity and eliminates background noises, for better understanding between call participants.
* Voice separation - clear, distinct voices mean participants know who said what.
* Everyone participates - allows users to focus on a particular conversation, even when people are talking over each other (often referred to as the cocktail-party effect). Everyone can be heard, not just the loudest, dominant talkers. This enables more natural interactions because more subtle audio cues are preserved.

BT has held more than 10 000 trial conferences of BT MeetMe with Dolby Voice, generating more than a million conference minutes. Nine out of 10 participants showed a strong preference for BT's MeetMe with Dolby Voice over their normal audio conferencing product.

A new report from the University of Cambridge, called: "Conversations, Conferencing and Collaboration: A UK investigation of factors influencing the effectiveness of distributed meetings"*, reveals that, according to 78% of participants, audio conferencing is still the most frequently used conferencing technology.

More than three quarters (77%) of the companies surveyed reported the high significance of sound quality to an effective call. Findings show that poor audio makes it hard to understand who is speaking, what is being said and in what emotional tone. This in turn leads to increased fatigue levels for participants and decreased productivity.

Efficient speaker identification was felt to be crucial to a successful conference call by 61% of participants, while 57% stressed the high importance of muting background noise. Experts interviewed for the report believe that spatial audio (separating speakers' voices) addresses these problems.

Dr Anna Mieczakowski, at the University of Cambridge, said: "Poor sound quality puts pressure on participants' hearing and thinking capabilities, which can result in tiredness and impair people's concentration and contributions to the meeting, as well as having a negative effective on secondary tasks such as note-taking. By improving the sound quality of a call, participants will be less stressed and less tired, and thus in a better position to clearly communicate their views and understand those of other attendees."

Howard Dickel, CEO BT Conferencing, said: "The research from Cambridge shows that conference call users believe higher sound quality would greatly improve the efficiency of their calls. We believe this would be a major factor in speeding up decision-making processes. Our partnership with Dolby will radically improve the quality and dynamics of conference calls, and because of this we expect businesses and their staff to get greater value from the experience. BT will be selling this through its BT One portfolio of unified communications and collaboration solutions."

Andrew Border, VP, Communications Business Group, Dolby, said: "Audio conferencing is an essential tool for conveniently and affordably connecting distributed and mobile workers. But current solutions suffer from technical limitations that prevent natural interactions. BT MeetMe with Dolby Voice makes conference calls sound and feel more like everyone is in the same room, which encourages participation, spontaneity, and collaboration, resulting in more productive meetings."

The new service, developed in partnership by BT and Dolby, builds on the existing capabilities of BT's MeetMe audio conferencing service, currently used by thousands of businesses worldwide. It is part of a series of new collaboration services launched by BT intended to transform the quality of business conversations and greatly improve the way people work together within and between organisations.

BT MeetMe with Dolby Voice is a subscription-based service which can be integrated with existing collaboration tools. The Dolby Voice client software is seamlessly integrated into BT MeetMe WebJoin. This software runs on standard PCs and Macs, and Dolby Voice can be delivered through a standard stereo headset. Callers can join over a standard phone line if they are unable to access the software. A mobile version for iOS and Android devices will be available shortly.

Key behaviours:

* Audio-based solutions are the most frequently used conferencing technology
* More than 50% of calls last between 30 minutes and one hour

Top five ways to improve conferencing:

1. Using reliable technology;
2. Having good sound quality;
3. Good management of distributed teams;
4. Effective chairing of distributed meetings; and
5. Focused participation from individual attendees.

Notes to editors

* The research was conducted by University of Cambridge Engineering Design Centre and completed in October 2013.

Comments from participants have been overwhelmingly positive:

* "Scarily good - had to keep looking round to check they weren't in the room with me."
* "I love it, I love having the controls online. It was really easy to use and the sound quality was brilliant!"
* "Absolutely marvellous - how can you ever go back to previous standard service now?"
