「瑪麗有隻小棉羊」是愛迪生錄製的第一句話，當他聽到機器重放這句話時，他很驚訝。1878年，愛迪生創建了專門販售此一新機器的愛迪生說話留聲機公司(Edison Speaking Phonograph Company)。

愛迪生建議將留聲機應用在其他方面，如：寫信及聽寫、盲人專用留聲書、家庭記錄(錄製家中成員的聲音)、音樂盒及玩具、報時時鐘或將留聲機與電話做結合，這樣一來就可以記錄通話內容。時至今日，有多少用途已經應用在現今社會中？

"Mary had a little lamb" were the first words that Edison recorded on the phonograph and he was amazed when he heard the machine play them back to him. In 1878, Edison established the Edison Speaking Phonograph Company to sell the new machine.

Edison suggested other uses for the phonograph, such as: letter writing and dictation, phonographic books for blind people, a family record (recording family members in their own voices), music boxes and toys, clocks that announce the time, and a connection with the telephone so communications could be recorded. How many of these uses have become a reality today?
