Package: mcvqoe-mouth2ear
Mouth-to-Ear Latency MeasurementPurposeThe purpose of this software is to measure the mouth-to-ear (M2E) latency of a
push-to-talk network. M2E latency characterizes the time between speech input
into on communications device and its output through another. M2E latency has
been identified as a key metric of quality of experience (QoE) in communications.
NIST's PSCR group developed this software to measure and quantify the M2E latency
of Push To Talk (PTT) devices.OBTAINING SOFTWAREMouth-to-ear latency measurement software available at:https://github.com/usnistgov/mouth2earMCV QoE GUI software available at :https://github.com/usnistgov/mcvqoeCore MCV QoE library available at :https://github.com/usnistgov/mcvqoe-baseMORE INFORMATIONData available at:https://doi.org/10.18434/M31865Paper available athttps://doi.org/10.6028/NIST.IR.8206Hardware Requirements2 computers able to run Python (only one needed for one location measurements)2 audio interfaces (only one needed for one location measurements)2 timecode generators with IRIG-B outputs (not needed for one location measurements)QoE hardware2 push-to-talk communications devices for testingCables to connect test devices and timecode generators (if used) to audio interfacesInstallation and SoftwareTo install this package runpip install mcvqoe-mouth2earAlternatively, to install themcvqoe-mouth2earpackage, clone this repository and run the
following from the root of the git repository:pip install .Themcvqoe-basepackage is required for install, it can be found athttps://github.com/usnistgov/mcvqoe-base.It is also recommended to install themcvqoepackage which has the measurement GUI to make measurements easier and more intuitive to run.
