    [0001] An electronic device comprising a wakeup module of an electronic device separate from a treatment core Embodiments of the invention relate to electronic devices comprising a processing core and a separate module intended to wake up from a voice command. the electronic apparatus, for example a cellular mobile telephone, in which the device is implanted. Electronic devices, including cellular mobile phones, connected watches and connected glasses, are increasingly equipped with modules for performing speech recognition. This function makes it possible to control the electronic device vocally. In order for the device to detect voice commands at any time, it is desirable to monitor and detect the signals of the environment of the device and in particular of its sound environment. Battery-powered electronic devices such as cellular mobile phones face a problem of optimizing power consumption during continuous monitoring of the sound environment for possible voice commands. To save the battery of an electronic device, the latter generally comprises a standby mode in which the power supply is kept to a minimum to keep a minimum of electronic elements in operation. However, when the electronic device is in standby, it must go out of sleep before it can perform the process related to the voice command. A user usually wants to be able to access device features quickly. It is thus necessary to be able to quickly leave the state of standby to answer a command of the user. One possibility is to provide a reactivation button.
    [0002] Similarly, when the electronic device is not in standby, but in an active state, the electronic device does not distinguish itself from a voice command sent to it from a voice command to a destination. other device. It is therefore necessary to provide a method for distinguishing when a voice command is addressed to the apparatus. An example of a known method for detecting the surrounding sound environment is the continuous audio process, or "continuous audio processing" in English, for waking a telephone. This type of method is known as "Always ON Audio" or "AON Audio" because the voice recognition audio means are kept powered and in continuous operation. The major disadvantage of such a system is the high energy consumption given the continuous power supply of the voice recognition means. According to one embodiment, there is provided an electronic device whose architecture minimizes the energy consumption of an electronic device in which it is mounted, the apparatus further comprising a voice command recognition system. According to one aspect, there is provided an electronic device comprising a processing core and an auxiliary module coupled to the core and distinct from said core, the core comprising a first power supply circuit, a first clock and multiple voice command recognition means 25 clocked by the first clock. According to a general characteristic of this aspect, the core has a standby state and the annex module comprises: a second supply circuit independent of the first supply circuit, a second clock independent of the first clock and having a frequency less than that of the first clock, a digital processing block clocked by the second clock comprising at least a first capture means 3030177 3 of a first sound signal, and configured to deliver a processed sound signal, and a processing unit configured to, in the presence of a parameter of the processed sound signal greater than a threshold, analyzing the content of the processed sound signal and delivering, when the content of the sound signal comprises a reference pattern, an activation signal to the heart able to release it from his waking state. Since the second supply circuit intended to supply the auxiliary module is independent of the first supply circuit intended to supply the core or the remainder of the electronic elements of the apparatus, the second supply circuit can be sized and configured to 'feed that the annex module. Thus, the energy consumption is minimized by adapting the second power supply circuit to the annex module. By providing a second clock only for the auxiliary module with a frequency lower than the frequency of the first clock intended to clock the heart and / or the other electronic elements of an electronic device comprising the device, the energy consumption of the module is scaled down. Indeed, the lower the frequency of a clock, the lower the energy consumption. Thus, by clocking the auxiliary module using a low frequency clock, the electrical energy necessary for supplying the auxiliary module is reduced in particular with respect to the core whose elements are clocked by a higher clock. frequency. The necessary power supply being reduced, the second power supply circuit can be all the more reduced compared to the power supply circuit of the heart. The parameter of the processed sound signal may be, for example, the average level of the sound signal, or its peak factor, or the level of this signal at different frequencies, without these examples being limiting. The first capture means may be a digital or analog microphone.
    [0003] 3030177 4 Since the auxiliary module is intended for the output of the standby mode of the electronic device in which the electronic device is installed, the processing unit can be configured to wake up the electronic device, in particular the heart of the device, only In response to detecting a reference pattern such as a keyword. The second clock may advantageously be less precise than the first clock. Indeed, a clock requiring less precision consumes less power. Advantageously, the processing unit may have a standby state and may be configured to exit its standby state in the presence of the processed sound signal level above the threshold. By putting the processing unit of the annex module on standby, the energy consumption of the annex module can be reduced as long as a processed sound signal does not exceed a detection threshold corresponding for example to a sound level threshold of the signal processed. Thus, for example, when the processing unit is in standby, only the digital processing block and a comparator configured to compare the sound level of the processed sound signal with a sound level threshold 20 are fed and clocked by the second clock. especially in decibel. The processing unit is therefore released from its standby state only in the case where a sufficiently strong sound has been picked up by the digital processing block. In this embodiment, the annex module preferably comprises a local interconnection circuit capable of coupling the processing unit to said second clock to make it leave its idle state. When the processing unit is in standby, it is coupled to the second supply circuit which supplies it, and decoupled from the second clock so as to minimize its electrical consumption. Advantageously, the digital block may comprise a single capture means, the processed sound signal corresponding to the sound signal captured by the only digital capture means.
    [0004] The capturing means is preferably a digital microphone positioned on the electronic apparatus so as to perceive the voice commands emitted by the user's mouth. Alternatively, the digital block may include a first capture means and at least one additional capture means disposed at a location separate from the first capture means and configured to capture an additional sound signal, and processing means configured to reduce the ambient noise from the first sound signal and the additional sound signal so as to deliver the processed sound signal. The first capture means may be a digital microphone disposed for example on the front of a telephony device, facing the mouth of a user for example, so as to capture the user's commands.
    [0005] The additional capture means may be digital microphones mounted on the back side of the cellular mobile telephone so as not to be facing the user's mouth. This arrangement allows the additional microphones to pick up environmental sounds that can pollute the sound signal from the mouth of the speaker and may interfere with the detection of voice control in the signal. In the case where a plurality of additional capture means are used, the additional sound signals are advantageously combined with weighting coefficients so as to obtain an equivalent additional sound signal which is then in particular subtracted from the first sound signal. In another aspect, there is provided an electronic apparatus comprising an electronic device as defined above. The electronic apparatus preferentially forms a cellular mobile telephone. Other advantages and characteristics of the invention will appear on examining the detailed description of an embodiment and an embodiment of the invention, in no way limiting, and the appended drawings, in which: FIG. 1 represents, schematically, an electronic apparatus comprising an electronic device according to one embodiment of the invention; FIG. 2 shows a flowchart of a control method of the electronic device of FIG. 1 according to one embodiment of the invention. In Figure 1 is schematically shown an electronic apparatus comprising an electronic device according to one embodiment of the invention.
    [0006] In the embodiment shown, the electronic apparatus 1 is a cellular mobile telephone comprising reception transmitting means which may comprise an antenna 1. The electronic apparatus 1 comprises a battery 2, a first coupled general power supply circuit 3 to the battery 2 and to the electronic elements of the apparatus 1, and in particular to an electronic device 4. The electronic device 4 comprises an electronic processing core 5 and an electronic module 6 separate from the heart 5. The core 5 comprises a first power supply circuit 7 20 connected as input to the general power supply circuit 3, a first clock 8 having a first clocking frequency and means 9 for recognizing multiple voice commands clocked by the signal of the first clock 8 and powered by the first power supply circuit 7. The means 9 for recognizing multiple voice commands comprise in particular a microphone processor configured to recognize a plurality of different voice commands and issue these commands to a microprocessor of the apparatus 1 for controlling the functions related to the commands.
    [0007] The annex module 6 comprises a second power supply circuit 10 connected at the input to the general power supply circuit 3 and independent of the first power supply circuit 7 of the core 5. The additional module 6 further comprises a second clock 11 independent of the first clock 8 and having a second clocking frequency lower than the first clocking frequency of the first clock 8 of the heart 5. The lower the frequency of a clock, the less this clock consumes electrical energy. In fact, the second clock 11, and therefore the annex module 6, consumes less electrical energy than the core 5 in operation. The annex module 6 furthermore comprises a digital processing block 12 powered by the second supply circuit 10 and clocked by the second clock 11. The digital processing block 12 comprises a first digital microphone 13 fixed on a front face 10 of the device 1 so as to be next to the mouth of a user and to receive voice commands from the user. The digital processing block 12 also includes a second digital microphone 14 fixed on a rear face of the apparatus 1 so as not to face the user's mouth and to pick up the surrounding noise. Microphones 13 and 14 may also be analog microphones coupled to an analog / digital conversion means. The digital processing block 12 comprises processing means 15 able to receive the sound signal captured by each of the two digital microphones 13 and 14 and to deliver a processed sound signal as far as possible free of ambient noise. In the case of a digital processing block 12 comprising only a single digital microphone, the processed signal delivered by the digital processing block corresponds to the sound signal captured by the single digital microphone. In the illustrated embodiment, the processing means 15 are configured to deliver a processed sound signal whose ambient noise has been reduced or suppressed, from the sound signal 30 captured by the first digital microphone 13 placed on the front face of the sound. 1 and the sound signal captured by the second digital microphone 14 placed on the rear face of the device 1 to capture the ambient noise. The processing means 15, including in particular subtraction means, thus deliver a clean processed sound signal from the ambient noise in which there remains essentially the voice command of the user if there is one. The digital processing block 12 thus continuously records via the two digital microphones 12 and 13 of the low frequency sound. The processing means 15 of the digital processing block 12 comprise a decimation input stage of the sound signals received from the digital microphones 13 and 14 in order to create samples of sound signals to be processed and possibly analyzed. The annex module 6 further comprises a comparator 16 and a processing unit 17, for example a microcontroller, configured to analyze the contents of the processed sound signal. The input of the comparator 16 is connected to the output of the digital processing block 12 to receive the processed sound signal, and the output of the comparator 16 is connected to a control input of the processing unit 17. Comparator 16 compares for example, the sound level of the sound signal processed at a detection threshold corresponding to a sound level in decibels. The processing unit 17 has a standby state in which its clock input is blocked so that the processing unit 20 is no longer clocked by the signal of the second clock and does not work. The processing unit 17 still remains powered by the second power supply circuit 10 during its standby state. When the processed sound signal is above the threshold, the comparator 16 outputs an activation signal to the processing unit 17. The activation signal controls the unblocking of the clock input of the processing unit 17. The standby output of the processing unit 17 is therefore characterized by a resumption of its timing by the signal of the second clock 11. At the same time as the activation signal of the processing unit 17, the comparator also transmits the processed sound signal 17 for analysis by the processing unit 17. In a variant, the digital processing block 12 could deliver the processed sound signal to both the comparator 16 and the processing unit 17, the comparator 16 then delivering only the activation signal of the processing unit 17 when the sound level of the processed sound signal is greater than the detection threshold. If the processed sound signal has a sound level below the threshold, the activation signal is not delivered which causes the processing unit 5 does not go out of its standby state and the sound signal is not processed. not analyzed by the processing unit 17. In another variant, the comparator 16 can deliver the activation signal to a local interconnection circuit included in the annex module 6 only, the processing unit 17 and the second 10 clock 11 being connected via the interconnection circuit. When the processing unit 17 has come out of its standby state, it analyzes the processed sound signal received. The analysis comprises a search for a reference pattern corresponding, for example, to the sound signal of a key word for waking the apparatus 1. The search is made in a conventional manner, for example by frequency comparison of the sound signal with the frequency signature. of the reference motif. If the reference pattern is detected, the processing unit 17 delivers a reactivation signal of the electronic device 1 and in particular of the core 5.
    [0008] The electronic device 4 comprises an interconnection circuit 18 making it possible to connect the output of the processing unit 17 of the annex module 6 to the processing unit 9 of the core 5 to control the activation of the core 5. In the figure 2 is a flowchart of a method of controlling the electronic device 4 of FIG. 1 according to an embodiment of the invention. In a first step 100, the sound is continuously captured using the two digital microphones 13 and 14. In a following step 102, the captured audio signals are decimated to obtain successive samples of constant size. Then, in a step 104, the sound signal is processed to reduce the ambient noise from the sample of the sound signal captured by the second digital microphone 14 and the corresponding sample of the sound signal captured by the first digital microphone 13. The processed sound signal is thus cleaned of the ambient noise and essentially comprises the voice command of the user if there is one.
    [0009] In a following step 106, the processed sound signal is then compared with an activation threshold of the processing unit 17. If the sound level of the processed sound signal is below the activation threshold, it returns to the step initial 100 to analyze the next sample.
    [0010] On the other hand, if the sound level of the sound signal processed is greater than the activation threshold, the processing unit 17 is woken up in a step 108. The alarm, ie the reactivation, of the unit processing 17 is performed by resuming the timing of the processing unit 17 by the signal of the second clock 11; In a next step 110, the processing unit 17 searches for the presence of the reference pattern in the processed sound signal. If the reference pattern is not detected in the processed sound signal, the processing unit 17 is switched back to its standby state and ceases to be clocked by the second clock 11, and returns to the initial step 100. On the other hand, if the reference pattern is detected in the processed sound signal, the processing unit 17 delivers, in a step 114, an activation signal of the heart 5. The core 5 is then activated as well as the means for recognizing multiple voice commands.
    [0011] This device makes it possible to have an electronic device configured to receive a wakeup voice command from the apparatus before receiving voice commands to request the apparatus to perform certain specific functions. Thus, to request the device, while in standby, to perform a function, it is sufficient to transmit the single voice command followed by a voice command to perform the desired function. This can be done, for example, from a wake-up keyword and a request phrase for the function to be performed.
    [0012] The architecture of the electronic device furthermore makes it possible to perform these functions while minimizing the energy consumption of the apparatus, by enabling reduced standby operation still allowing the reception of a wakeup voice command, and so on. to increase the life of the electronic device between two refills.
