Button control mode is flexible to trigger and free to set any button to re-trigger .There are 15 trigger ways. Including trigger Impulse Repetition , trigger pluse Without Repetition , invalidation keys, no cycle Level , Recycled Level , Non-Maintained Cycle Level, Non-Cycle for The Last One ,Non-Cycle for The Next One , Cycle for The Last One , Cycle for The Next One, Volume +, Volume -, play / pause, stop, play / stop, etc .
One-wire serial control mode and three-wire serial control mode, not only can control voice play, stop, loop play and volume size by the MCU, but also can direct triggering any voice in address bit from 0 to 219.
Widely range of applications. Almost related to all the voice places, such as Stop devices, annunciators , reminder, alarm clock, learning machine, intelligent home appliances, therapeutic equipment, electronic toys, telecommunications, reversing radar and a variety of automatic control devices, etc. Technology meet up to the requirements of industries application.
