Abstract
An electronic device includes an appended module coupled to a core having a standby state comprising a first power supply circuit, a first clock and a circuit that recognizes multiple vocal commands timed by the first clock. The appended module includes a second power supply circuit independent of the first power supply circuit, a second clock independent of the first clock and having a frequency lower than that of the first clock, digital unit timed by the second clock including a sound capture circuit that delivers a processed sound signal, and a processing unit configured in order, in the presence of a parameter of the processed sound signal greater than a threshold, to analyze the content of the processed sound signal and to deliver, when the content of the sound signal comprises a reference pattern, an activating signal to the core that can take it out of its standby state.
