Shortly after the invention of the synthesizer technology to reproduce human speech with tuned voices stored in ROM's (integrated circuits) Texas Instruments introduced the Language Tutor. About one year later this product was renamed to Language Translator and the selling price was reduced. An even cheaper variant called Language Teacher lacked the speaker and gave the translation only on the display. 

An easy accessible "Solid State Speech™ Module" contained the software to translate from e.g. English, French and Spanish to German. LanguageTeacher_GER.jpg (52762 Byte)
