Voice Interface Takes Users' Hands Off Scopes

By speaking verbal commands into a collar-mounted microphone, users of the firm's Infiniium oscilloscopes can have both hands free for probing of fine-pitch circuit boards while maintaining control of measurements, on-screen waveform views and printing of waveforms. The optional voice-control facility is useful when: probing multiple signals concurrently; working under potentially dangerous circumstances with high voltages; or when operating scopes in potentially unsafe areas such as environmental test chambers.A natural-language, English command set enables users to adjust all primary controls. The scheme is speaker- and gender-independent, so users don't have to train the scope to recognize their individual voices. The voice-control option was designed using Lernout & Hauspie's ASR1600 phonetic speech-recognition engine.
