Titles read: "MACHINE MADE VOICES!"
Hollywood, California, United States of America.
In a Hollywood CBS recording studio we see American film star actress Lucille Ball telling us she has just travelled cross-country by train. She holds two small amplifiers against her throat and mouths some words. The amplifiers transform the sound of a steam train coming from a record into 'steam train words' picked up by Lucille's larynx. I cannot make out all of them - the last are "Hello everybody".
Three technician men sit at a table wearing headphones and making notes. Lucille does another demonstration - this one seems to be 'cow words' - very difficult to decipher. I guess it was still in the early stages!
