-Consider the word _hotdog_. You can't hear the t, but the articulation is complete. So instead of hearing ˈhɑtˌdɔg or ˈhɑˌdɔg, you hear ˈhɑ·ˌdɔg – the · represents a stop created by the t sound's complete articulation without any audible output. Try the same with _network_ ˈnetˌwərk – the t applies the same principle. (Note, some people pronounce the t in this context using a _glottal stop_.)
