A voice-activated signal generator is a device to produce output signals responsive to spoken commands. The device accepts only predetermined commands and responsively generates specific output signals such as a pulse, a series of pulses, a voltage level, or a periodic waveform. The device is suitable for triggering an oscilloscope, or controlling a circuit under test, or activating another instrument. The invention also enables safely controlling a hazardous system such as a high voltage system, hands-free and with precise timing determined by the user. Also disclosed are fast, compact, robust algorithms for analyzing spoken commands, and particularly for detecting voiced and unvoiced sound, and for identifying commands by comparing the order of sound intervals in the spoken command to templates that represent the predetermined commands. The device may have one output or multiple outputs in parallel, all controlled by voice commands with precision output timing. |
