Interprete ES⇄EN is an OS-level simultaneous interpreter for video calls. I understand English, but in a live interview or meeting I freeze when I have to speak it, and most of the jobs I want are remote and in English. You speak Spanish (or Spanglish) into your normal microphone, and the other side hears fluent English. They speak English, and you read their words as Spanish subtitles and hear them in Spanish. It runs beside the call app, at the level of Windows, so the only setting is picking "CABLE Output" as the microphone. Nothing to install on the other side. Tested with Google Meet; Zoom, Teams and other apps take a microphone the same way, but were not tried. Meta end to end: Muse Voice Transcribe hears both sides live; Muse Spark translates each clause with the whole conversation and a glossary as context, and also guides the setup through tool calls; Meta's open-weight MMS-TTS speaks English and Spanish locally on the CPU. The English starts about 4 seconds after I start speaking, and in a 10-minute Google Meet call, 212 of 213 clauses played. The video shows a real interview in Google Meet. Windows 11.
