function: generate(text_arr = [""], save_path = None)
arguments: 
text_arr (array) : an array of strings
save_path (string, optional) : location where generated wav files will be stored if save_path is not None, if the path is not valid, the wav files will be saved in current directory
returns:
if save_path is None, instead of saving an array of tuples containing geenrated speech signals and the sampling rate will be returned
if save_path is not None, then a list containing the file paths (relative) will be returned
