ETSI STQ Conference: Communications for All, 
Supporting Diversity and Accessibility through Quality of End-to-end Network Transmission
and Devices in Human-to-human and Human-to-machine Communication
13-14 May 2025
ETSI, Sophia Antipolis France

ETSI Technical Committee Speech and multimedia Transmission Quality (TC STQ) is pleased to announce that the ETSI STQ Conference: Communications for All - Supporting Diversity and Accessibility through Quality of End-to-end Network Transmission and Devices in Human-to-human and Human-to-machine Communication, will take place face-to-face in ETSI Premises, Sophia Antipolis, France on 13-14 May 2025. 

The event is free of charge, open to all upon mandatory registration. The agenda is online. Register now! 

 About the event

This face-to-face conference aims at bringing together communities that have not been well-connected to standards development in speech and multimedia transmission until now. ETSI TC STQ recognizes the need to bring more inclusivity to technical standards on the quality of network transmission and devices on speech and multimedia in human-to-human and human-to-machine communication, to ensure that diverse groups have input into the work of STQ.  

Standardization of measurement and evaluation methods for speech and multimedia devices and networks is crucial to ensure that all users receive high quality of service and high quality of experience.  Previous work in ETSI TC STQ has focused on human perception of speech and audio, as well as network-enabled services.  However, with some exceptions, various aspects of accessibility still need to be addressed. 

In order to bridge this gap, this conference will provide a venue for interested advocates and communities to present and discuss issues of relevance, that so far have not been at the centre of technical standards development. The Programme Committee encourages a wide range of inputs and views to help inform and guide future work on diversity and accessibility.

Target Audience

The event is addressed to:

  • Affected / relevant user groups,
  • Research bodies,
  • Regulators, 
  • Manufacturers,
  • Systems Integrators, 
  • Service providers,
  • Network Operators

The agenda is now avalailable.

Additional information to attendees: should you have accessibility needs, please contact us and we will do our best to accommodate them.
