DETAILED DESCRIPTION
All of the processes described may be embodied in, and fully automated via, functional code modules executed by one or more general purpose computers or processors. The code modules may be stored in any type of computer-readable medium or other storage device. Some or all of the methods may alternatively be embodied in specialized computer hardware or electronic apparatus.
FIG. 1 is a block diagram of one embodiment of a mobile electronic device 100 comprising a seeking system 10 for locating the mobile electronic device 100. In this embodiment, the mobile electronic device 100 further includes a storage system 20, a processor 30, a voice command input unit 40, and a ringing circuit 50. When the mobile electronic device 100 is in a silent mode, and a received call is regarded as a missed call, the seeking system 10 may receive a voice command input by a user via the voice command input unit 40. Furthermore, the seeking system 10 may compare the input voice command with a pre-recorded standard voice command. If the input voice command satisfies a voice identification standard, the seeking system 10 may activate the ringing circuit 50 to play a predetermined ring tone. In other words, when a user misplaces his phone, he can first call his phone from another phone to listen for the ring tone. If the phone is in a silent mode, the unanswered call activates the seek function of the phone, where the user can speak a pre-determined command, for the phone to respond with a ring tone, thus making the phone easier to find.
In one embodiment, the standard voice command and the voice identification standard may be audio files that are stored in the storage system 20. The storage system 20 also stores one or more computerized codes of the seeking system 10. The processor 20 executes the one or more computerized codes of the seeking system 10, to provide function of the seeking system 10 described above.
Depending on the embodiment, the mobile electronic device 100 may be a mobile phone, a personal digital assistant, or any other suitable portable electronic device. The storage system 20 may be a read only memory (ROM), an electrically erasable, programmable, read only memory (EEPROM), a random access memory (RAM), or any other kind of memory. The voice command input unit 40 may be a microphone or any other electronic device that may record and/or recognize voice commands.
FIG. 2 is a block diagram of function modules of the seeking system 10 in FIG. 1. In one embodiment, the seeking system 10 includes a setting module 110, a detecting module 120, an activation module 130, and a voice identification module 140.
The setting module 110 receives the standard voice command input by the user. The standard voice command may be audio files that have been pre-recorded using the voice command input unit 40. For example, the standard voice command may be the phrase, “one, two, three, four.” It may be understood that the user may be a manufacturer of the mobile electronic device 100, or a buyer of the mobile electronic device 100. If the standard voice command is input by the manufacturer or other users, the buyer may listen to a record of the standard voice command, so as to control pronunciation when speaking to the voice command input unit 40 so as to input the standard voice command correctly.
The setting module 110 further receives the voice command identification input by the user. In one embodiment, the voice command identification standard defines a similarity degree between characteristics of any voice command and the characteristics of the standard voice command For example, the similarity degree may be set as 30%. The characteristics of a voice command may comprise a frequency, amplitude, a volume and a pulse width of the voice command.
The detecting module 120 detects if the mobile electronic device 100 receives a new call, and detects if the new call is regarded as a missed call.
The activation module 130 activates the voice identification module 140, in response that the new call detected by the detecting module 120 is regarded as a missed call.
The detecting module 120 further detects a voice command, such as a current pronunciation of “one, two, three, four” input by the user via the voice command input unit 40.
The voice identification module 140 compares the characteristics of the voice command with the characteristics of the standard voice command, determines if the voice command satisfies the voice command identification standard. For example, the voice identification module 140 compares each character (e.g., the frequency) of the voice command with a corresponding character (e.g., the frequency) of the standard voice command, to determine if the similarity degree between each characteristic of the voice command and the corresponding characteristic of the standard voice command is more than or equal to 30%.
The activation module 130 activates the ringing circuit 50 to play a predetermined ring tone (e.g., a song) in response that the voice command satisfies the voice command identification standard (e.g., degree of similarity >=30%), so that the user may find the mobile electronic device 100 according to the predetermined ring tone. After playing of the ring tone, for example, the user may pausing the playing of the ring tone once the mobile electronic device 100 has been located, so that the activation module 130 will shut down the voice identification module 140 automatically.
FIG. 3 is a flowchart of one embodiment of a method for locating the mobile electronic device 100 having the seeking system 10 in FIG. 1. Depending on the embodiment, additional blocks may be added, others removed, and the ordering of the blocks may be changed.
In block S301, the setting module 110 receives a standard voice command and a voice command identification input by the user of the mobile electronic device 100. For example, the standard voice command may be the phrase “one, two, three, four.” As mentioned above, the voice command identification standard defines a similarity degree between characteristics of any common voice command and the characteristics of the standard voice command. For example, the similarity degree may be set as 30%. The characteristics of a voice command may comprise a frequency, amplitude, a volume and a pulse width of the voice command.
In block S303, the detecting module 120 detects a missed call received by the mobile electronic device. Because the mobile electronic device 100 is in a silent mode, an incoming call may be regarded as a missed call.
In block S305, the activation module 130 activates the voice identification module 140.
In block S307, the detecting module 120 detects a voice command, such as a current pronunciation of “one, two, three, four” input by the user via the voice command input unit 40. For example, the voice command input unit 40 may be a microphone.
In block S309, the voice identification module 140 compares characteristics of the voice command with characteristics of the standard voice command For example, the voice identification module 140 respectively compares a frequency, amplitude, a volume and a pulse width of the voice command with a frequency, amplitude, a volume and a pulse width of the standard voice command.
In block S311, the voice identification module 140 determines if the voice command satisfies the voice command identification standard. For example, the voice identification module 140 determines if the similarity degree between each characteristic of the voice command and a corresponding characteristic of the standard voice command is more than or equal to 30%. If the common voice command satisfies the voice command identification standard (e.g., the degree of similarity >=30%), the procedure goes to block S313. Otherwise, if the voice command does not satisfy the voice command identification standard (e.g., degree of similarity <30%), the procedure ends.
In block S313, the activation module 130 activates the ringing circuit 50 to play a predetermined ring tone, such as a song, for example.
In block S315, after playing of the predetermined ring tone, for example, the user may pausing the playing once the mobile electronic device 100 has been located, the activation module 130 shuts down the voice identification module 140 automatically.
According to above embodiments, even if a mobile electronic device is in a silent mode, a user of the mobile electronic device can locate the mobile electronic device via calls and voice commands. Furthermore, the seeking function is shut down upon the condition that no call is received by the mobile electronic device, so as to save power of the mobile electronic device.
It should be emphasized that the above-described inventive embodiments are merely possible examples of implementations, and set forth for a clear understanding of the principles of the present disclosure. Many variations and modifications may be made to the above-described inventive embodiments without departing substantially from the spirit and principles of the present disclosure.
