I have an Arduino UNO connected to DFR0760 Speech Synthesis V2 that will not changing voices no matter

which voice I select to compile for. No error messages just the same female voice. I can change volume no problem.

Below is the program that I am using taken from V2 lib I2C example. Please advise:

/*Use text control identifier*/
//Voice volume identifier
