467: Talking Books at 90 - The First Recorded Voices (and the equipment used)

From the phonautograph to a smart speaker, today's Read On not only looks at the history of 90 years of RNIB Talking Books recording (and the equipment used), but goes back to the invention of recording as a whole. 

We hear the first recorded voices, about the format war between cylinder and disc, about the phonautograph, the phonograph, the graphophone and the gramophone, to single track magnetic tape, DAISY CDs and Alexa Skills and more in this 169 year trek through the history of recording the human voice.
