Abstract
A computer system has a power-down mode to conserve energy. The computer system includes a speech transducer for capturing speech; a low-energy consuming power-up indicator coupled to said speech transducer, said power-up indicator detecting speech directed at said speech transducer and asserting a wake-up signal to a powered-down processor; and a voice recognizer coupled to said speech transducer and said wake-up signal, said voice recognizer waking up from the power-down mode when said wake-up signal is asserted.
Claims10
A computer system having a power-down mode to conserve energy, comprising:
- a speech transducer for capturing speech;
- a low power wake-up indicator coupled to said speech transducer, said wake-up indicator detecting speech directed at said speech transducer and asserting a wake-up signal to a powered-down processor, the low power wake-up indicator having a low pass filter and a power comparator coupled to the low pass filter;
- and
- a voice recognizer coupled to said speech transducer and said wake-up signal, said voice recognizer waking up from the power-down mode when said wake-up signal is asserted.
A computer system having a power-down mode to conserve energy comprising:
- a speech transducer for capturing speech;
- a neural network coupled to said speech transducer, said neural network detecting speech directed at said speech transducer and asserting a wake-up signal to a powered-down processor;
- and
- a voice recognizer coupled to said speech transducer and said wake-up signal, said voice recognizer waking up from the power-down mode when said wake-up signal is asserted.
