As shown in the diagram above, if continuous playback is carried out, input the PLAY command for the second
phrase within 10 ms (tcm) after NCR goes “H”. This will make it possible to start playing the second phrase
immediately after the playback of the first phrase finishes. Phrases can thus be played back continuously
without inserting silence between phrases.
