For the echo playback of multiple phrases, the sampling frequency of each phrase must be the same.
If a phrase with a different sampling frequency is mixed, the voice of channel 2(ECHO) will be played
fast or slow because the sampling frequency of channel has priority. Figure 5 shows the timing.

ECHO PLAYBACK OF A SINGLE PHRASE WITHIN A PHRASE STRING
Table14 shows an edit data example to apply echo to "is" in the four phrases of "Today's", "weather",
"is" and "sunny".
