I retest our app in a controlled environment: one single speaker, quiet room with no noise, spoke with a normal sentence (less than 15 words) in 5 seconds but that still caused the framework to enter “processing speech…” to almost 50 seconds with high CPU utilization. During this period, the framework does not generate any output, nor does it handle any input (iphone UI is still functioning though). This is re-producable.
