Summary

Recommendation ITU-T P.1120 will provide guidance to systems architects, developers, and test engineers of integrated automotive speakerphones that operate around super-wideband (50‑14,000Hz) and/or fullband (20-20,000Hz) audio bandwidths.

Guidance is provided on the system level (i.e., mouth/ear-to-network reference point).

Subjective (i.e., perceptual) testing for validating a design under real life condition is provided in this Recommendation.
