#change the text
text="The election was won by businessman and politician, Moshood Abiola, but Babangida annulled the results, citing concerns over national security."

# change the language and voice
prompt=audio_tokenizer.create_prompt(text,lang="english",speaker_name="idera")

            #num_beams=5,# using a beam size helps for the local languages but not english
        )
