Mission Critical Voice Quality of Experience Mouth-to-Ear Latency Measurement Method

The 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 one 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 Public Safety Communications Research group developed this software to measure and quantify the M2E latency of Push To Talk (PTT) devices.
