Multidimensional Speech QoE

Lupe [1]

Perceptual analysis and evaluation of Quality of Experience (QoE) for speech services

Motivation & Project Description

  • Perceptual analysis and evaluation of the Quality of Experience (QoE) for important speech services:

    • Speech Transmission: Super-wideband speech quality dimensions
    • Speaker Characterization: User specific perception (age, gender, personality)
    • Speech Generation Factors: Text-to-speech (TTS) quality features
    • Interaction Factors: Multi-party conferencing quality aspects

  • Focus: Evaluating dimensions of QoE and their interaction

Expected Outcome:

  • Super-wideband E-model for network planning and monitoring
  • Improvement of DIAL (former ITU-T Rec. P.863 candidate by France Télécom R&D, Kiel University, and T-Labs)
  • ITU-T contributions and recommendations (ITU-T SG 12, Q.8/12, Q.9/12, and Q.18/12)
  • Automatic user characterization similar to (manual) professional assessment centers
  • Recommendations for TTS synthesis and multiparty conferencing system development
  • Scientific publications
