Media Quality and the User Experience We plan to complete a new TR on bandwidth calculations
In 2017, our Speech and Multimedia Transmission Quality and prioritisation in Voice over Internet Protocol (VoIP)
committee (TC STQ) will continue to work on terminals and systems, a new TS on methodologies, test arrangements and
network configurations using super-wideband and fullband requirements for evaluating the performance of wearable
for conversational services for teleconferences and audio- devices for speech communication, and a new TR on the
visual applications. With the standardisation of the new status of technical aspects of net neutrality including
Enhanced Voice Services (EVS) codec by the Third Generation broadband access aspects.
Partnership Project (3GPP™), mobile terminals are entering
the market which employ new designs and signal processing We are introducing new work on speech recognition in
adapted to new use cases. We will now develop testing response to emerging needs in the IoT for the testing,
and qualification procedures for these terminals and optimisation and qualification of voice-controlled devices
configurations. employing speech recognition. We will update our existing
specifications which allow the simulation of different
background noise scenarios in a laboratory type of
environment to accommodate the IoT. We will also develop
new testing techniques for the verification of different types
of devices using speech recognition in various acoustic
environments. We are developing methods and procedures
for evaluating the performance of voice-controlled devices
and functions which will result in the publication of a new TS
in 2018.
We are preparing a TS aimed at improving listening quality
for people with impaired hearing. Studies have shown that
people with impaired hearing may find transmitted speech
unintelligible for a variety of reasons including background
noise, transmission impairment, the shape of their receiver
and coupling between earphones and hearing aids. This new
specification will define requirements and measurement
methods to assess the impact of different transmission
impairments on intelligibility as well as a model to assess
speech intelligibility objectively.

Other new work in 2017 includes the development of
methodologies, test arrangements and requirements for the
evaluation of multimedia communication performance under
parallel physical and/or mental load (dual-task testing).
We are compiling best practices for throughput
measurements and expect to publish a new TR in 2018. We
will take into account issues raised at the ETSI workshop on
‘Multimedia Quality in Virtual, Augmented or other Realities’
held in May 2017. This new work is expected to lead to the
