Conferencing Quality


Motivation & Project Description

  • Current quality prediction models have been developed for 2 party conversations via telephone or Voice over IP, respectively.
  • For 3 or more participants (3+) conference calls, such models have not been designed and evaluated.
  • Furthermore, knowledge about Quality of Experience (QoE) in conferencing scenarios is limited.

Goal: to investigate effects on QoE between 2 participant calls and 3+ participant conferences

Expected Outcome:

  • Identify conferencing typical changes of system paramters (e.g. spatial audio reproduction)
  • that better explain conferencing typical effects on QoE (e.g. speaker separation effort)
  • to improve quality prediction models.

Time Frame:
