Dr. Greer’s relentless efforts towards the disclosure of classified UFO/ET information have inspired millions of supporters around the world.

Déjà Entendu ("Already heard" in French) allows iOS, iPadOS and macOS owners to dive into translate, transcribe and create flash cards from images, recordings or sound samples on their device. It is not a cloud service. So you can be assured that any use of the on-device content analysis that Apple Intelligence performs stays private to you. Import your class notes provided by teachers or translate mp3 files and audio clips that you've made or that you've purchased previously. New options for speeding or slowing pronunciation guides is introduced with the updated version along with options for direct speech input to the transcription tool. Social channels for extra How To instructions are accessible from the Home Tab. We hope you enjoy learning more of the languages that inspire you through our apps!
