    "description": "Example measurement results from the Mission Critical Voice (MCV) Quality of Experience (QoE) access delay measurement system. Access delay and mouth-to-ear latency combine to describe end-to-end access time. In particular access delay describes the minimum amount of time a transmitting user must wait between pressing PTT on a device and starting to speak to ensure that the start of their message is not lost.",

Access time generally describes time associated with the initialization and assignment of channels upon user request to speak and has been identified as a key component of quality of experience (QoE) in communications. NIST?s PSCR division developed a method to measure and quantify the access time of any push to talk (PTT) communication system.",
