A language translation system, comprising:

• one or more processors;
• a wearable head device including a microphone system and a see-through display, the wearable head device in communication with the one or more processors;
• a speaker adapted to produce sound intensity such that a person at a conversational distance can hear the sound at a conversational level, the speaker in communication with the one or more processors;
• and
• wherein the one or more processors are adapted to:
• receive a spoken utterance of a person wearing the wearable head display,
• convert the spoken utterance into a language other than a first spoken language represented by the spoken utterance, forming translated language,
• communicate the translated language to the speaker, and,
• display a visual representation of the translated language via the see-through display;
• wherein the speaker produces sound less than 80 db at a distance of 5 feet from the speaker.
