Live Translated Captions
SpeechSpeak into the mic: on-device captions appear instantly, and a second track renders them live in another language.
Why On-Device?
Recognition, detection, and translation all run locally — captions work offline and the audio never leaves the microphone's device. A babel fish in a browser tab.
