 【Background technique】

Currently, voice response systems have applications on some mobile devices. The technical idea of a general voice response system is to set a microphone for picking up a human voice on the mobile device to respond to the user's voice input, and a function key for initiating a voice response.

When working, first press the "Speech Response Function Key" to wake up the mobile terminal and inform the mobile device to activate the voice response function. When the user speaks a word to the mobile device's microphone, the mobile device records the spoken words and then compares them with the pre-stored voice data. If the same or similarity is above the required level, a voice response is triggered.

 【detailed description】

Referring to FIG. 1, FIG. 1 is a flowchart of an embodiment of a voice response method according to the present invention. The method includes:

Step S101: detecting a calling voice from the outside world;

The mobile device detects the external calling voice in real time through a voice pickup device such as a microphone.

Step S102: When the size of the calling voice of the outside exceeds the preset voice reference value for starting the voice response function, it is searched whether there is a calling voice sample that matches the calling voice;

The voice reference value can be expressed by the magnitude of the current or voltage, and of course other ways. Whether the size of the external call voice exceeds the preset voice reference value for starting the voice response function, and the corresponding measurement current or measurement voltage obtained by comparing the external call voice conversion can be compared with the preset function for starting the voice response. The current or voltage is carried out. For example, when the measured voltage corresponding to the external calling voice exceeds the preset voltage for starting the calling voice function, the voice response function is activated to find whether there is a calling voice sample matching the calling voice; when the external calling voice corresponds to When the measured current exceeds the preset current for initiating the calling voice function, the voice response function is activated to find whether there is a calling voice sample that matches the calling voice. In the following embodiments, the voice reference value is represented by a voltage as an example.

After the voice response function is activated, the calling voice function or other means can be used to continue to obtain the calling voice of the outside world, and the calling voice is converted into a calling voice signal that the mobile device can recognize; specifically, the external calling voice that continues to be acquired can be converted into a measurement. The voltage, in turn, converts the measured voltage into a calling voice signal that the mobile device can recognize.

When matching is performed, it is usually to find whether there is a calling speech sample that matches the speech feature of the calling speech signal. The matching here refers to that the similarity of the speech features of the calling voice signal reaches a preset similarity or above, and the preset similarity is set according to the user's needs, such as 85% or 75%, etc., Make restrictions. When there is a calling voice sample matching the calling voice, step S103 is performed; otherwise, returning to step S101 to continue detecting the calling voice of the outside world.

In the actual application process, it is possible to start the voice response function when the call is halfway, that is, after starting the voice response function, the call voice of the other half may be acquired, and only the remaining part is obtained. Calls voice and converts and matches. The conversion here includes two steps of converting the acquired call voice into a measurement voltage, and then converting the measurement voltage into a call voice signal that the mobile device can recognize. After converting the measurement voltage corresponding to the external calling voice into the calling voice signal recognizable by the mobile device, the mobile device searches for a calling voice sample that matches the voice feature of the calling voice signal.

On the other hand, there may be cases where the voice response function is activated at the end of the call voice. Since there are too few call voices that are subsequently acquired, there may be no matching. In this case, the response may not be performed, or may be performed by other means, for example. Set the start alarm sound, etc., prompting the user to make a call voice again.

Step S103: Perform a pre-stored response operation corresponding to the calling voice sample;

When there is a calling speech sample that matches the calling speech, a pre-stored response operation corresponding to the calling speech sample is performed. The response operation may be to play a pre-stored response voice corresponding to the call voice sample or perform an action corresponding to the call voice sample.

For example, the pre-stored call voice sample is "Dear", and the pre-stored response operation corresponding to the call voice sample is the voice playing "I am here." Then when the external voice is "Dear," the mobile device plays the voice "I am here." The owner of the mobile device can quickly find his mobile device. For example, the pre-stored call voice sample is “calling XXX call”, and the corresponding response operation is to automatically dial XXX. When the external voice is "calling a XXX call", the action of dialing the XXX call is performed.

It can be understood that the first embodiment of the present invention activates the following voice feature matching process by causing the mobile device to detect the calling voice from the outside world, so that the mobile device performs the pre-stored response operation corresponding to the calling voice sample, instead of using the prior art. The way the button is triggered makes the use of the mobile device more user-friendly, more convenient, and easier to use; the second is to sense the change of the external voice strength, only when the external voice size reaches the preset voice reference value for starting the voice response function. Only when the wake-up voice response function is controlled, the dynamic response is realized, and the power loss caused by the voice response function is turned on for a long time, so that the power consumption of the mobile device is lower.

In addition, the mobile device responds to the user's call to respond to a variety of ways, bringing more fun to the user's life.

Referring to FIG. 2, another embodiment of the voice response method of the present invention includes:

Step S201: setting a call voice sample and a response operation corresponding to the call voice sample and saving;

Setting a calling voice sample and a response operation corresponding to the calling voice sample on the mobile device side and saving the same in the mobile device;

Step S202: setting a voice reference value for starting the voice response function and saving;

A voice reference value for starting the voice response function is set in advance, and the voltage is used as a voice reference value. Assuming that the voltage is 350mV when the person utters a call, the voltage for starting the voice response function can be set to 350mV. Of course, the voltage for starting the voice response function can also be set according to the user's own requirements, for example, the setting is lower than 350mV or slightly higher. The voltage at 350 mV is the voltage used to activate the voice response function. In the actual application process, if the mobile device system itself already has a default voltage for starting the voice response function, the setting procedure of the voltage for starting the voice response function is not required, and the mobile device system is directly used by default. The voltage at which the voice response function is activated is used as a voltage for starting the voice response function;

It should be noted that the sequence of the above steps S201 and S202 can be reversed, that is, the voice reference value for starting the voice response function can be set and saved, and then the calling voice sample is set and corresponding to the calling voice sample. Respond to the operation and save;

Step S203: detecting a calling voice from the outside world;

Step S204: When the size of the calling voice of the outside exceeds the preset voice reference value for starting the voice response function, it is searched whether there is a calling voice sample that matches the calling voice;

Step S205: Perform a pre-stored response operation corresponding to the calling voice sample;

In the above manner, by setting a call voice sample and a response operation corresponding to the call voice sample in the mobile device in advance, the user can set these parameters according to personal preference, so that the voice response is more personalized, and the response manner is also based on the user. The personal settings have become more flexible and give users a richer experience.

In another embodiment, the specific steps of setting the calling voice sample and the response operation corresponding to the calling voice sample and saving are as shown in FIG. 3, as shown in the figure, including the following sub-steps:

Sub-step S301: receiving an instruction to record a call voice sample;

The mobile device receives an instruction to record a call voice sample generated from a user operation;

Sub-step S302: recording an external sound as a call voice sample;

After receiving the instruction to record the calling voice sample, the mobile device records an external sound as a call voice sample according to the instruction. The calling voice sample may be a name that the user takes for his mobile device, or may be another voice. For example, shouting "Dear" or "Love Machine" to the microphone of the mobile device as a call sample, or calling a mobile action command to the microphone of the mobile device, such as "calling a XXX call", etc. The present invention does not limit the specific form and content of the calling voice sample;

Sub-step S303: outputting a prompt to set a response operation corresponding to the calling voice sample;

After the call voice sample is recorded, the mobile device outputs a prompt for setting a response operation corresponding to the call voice sample;

Sub-step S304: receiving a response operation setting corresponding to the calling voice sample input according to the prompt;

The input operation is performed according to the prompt of the response operation corresponding to the call voice sample corresponding to the output of the sub-step S303, and the mobile device receives the input response operation setting corresponding to the call voice sample, and the response operation corresponds to the corresponding call voice sample, such as calling the voice. The sample is "Dear" or "Love Machine", and the response operation can be set to "哎" or "I am here" in response to the sound. Of course, you can also set some spoiled sounds or a piece of music as the answering sound; The voice sample is an action instruction such as “calling a XXX call”, and the response operation may be set to perform a corresponding response action such as dialing a XXX call;

Sub-step S305: saving the calling voice sample and the response operation setting corresponding to the calling voice sample;

The recorded call voice sample and the response operation settings corresponding to the call voice sample are saved to the mobile device to complete the setting.

It is worth mentioning that the above setting process is only an implementation manner of the setting process of the present invention. In practical applications, the recording of the calling voice sample operation and the response operation setting corresponding to the calling voice sample are not strictly distinguished, that is, It is said that after receiving the instruction to record the calling voice sample (ie, the above sub-step S301), the response operation setting may also be performed first to perform the calling voice sample recording. Moreover, it is not necessary to call the voice sample recording completion and the response operation setting is completed and then saved, and can be separately saved, that is, the voice sample recording is completed and saved, and then the response operation setting and saving, or the response operation setting is saved first. Then call the recording of the voice sample and save it.

Please refer to FIG. 4 , which is a specific application flowchart of a voice response method according to an embodiment of the present invention. The voice response method of the present invention is applied to a mobile phone, including:

Step S401: receiving an external sound;

The mobile phone continuously receives the sound of the outside world through the microphone.

Of course, before this, you can first set up the phone system. First, in the setting menu of the mobile phone, the voltage for starting the voice response function is set, and the calling voice sample and the response operation setting corresponding to the calling voice sample are set and saved on the mobile phone, and the similarity of the voice matching can also be set and saved. Of course, in the actual application process, if the voltage of the voice response function is limited within the mobile phone system, the voltage does not need to be reset, and the default voltage of the system is directly used as the voltage activated by the voice response function.

Step S402: processing the sound;

After the external sound passes through the mobile phone microphone, it can be converted into the measured voltage or measured current corresponding to the external sound.

The measured voltage corresponding to the external sound is sent to the voltage comparator for comparison.

Step S403: performing voltage comparison;

The mobile phone compares the measured voltage converted by the external sound with a preset voltage for starting the voice response function or the system's default starting voice response function through an internal voltage comparator. If the measured voltage exceeds a preset voltage for starting the voice response function to start the voice response function, step S404 is performed, and if the measured voltage does not exceed the preset voltage for starting the voice response function to start the voice response function, step S406 is performed. ;

Step S404: Start a voice response function, and perform voice matching;

When the measured voltage exceeds the preset voltage for starting the voice response function, the voice response function is activated, and the external sound is continuously received and converted into a sound signal recognizable by the mobile phone, and the voice sample matching the sound signal is searched in the mobile phone. After the voice response function is activated, the voltage comparison can be stopped to save power;

Step S405: If a speech sample whose similarity reaches 85% or more is found, a response operation corresponding to the speech sample is performed, otherwise, the response operation is not performed;

Step S406: No operation is performed;

When the measured voltage does not exceed the preset voltage for starting the voice response function, no operation is performed. For example, if the mobile phone is in the standby state, it continues to be in the standby state and continues to receive the external sound.

In the above manner, the mobile device does not require a button to trigger a voice response, making the use of the mobile device more user-friendly, more convenient, and easier to use. For example, the user can pre-set "Dear" as a call voice sample, and the corresponding response response is "Dear, I am here." When someone shouts "Dear," the mobile device will answer "Dear, I am here", very human; especially in daily life, when a person is at home, he often forgets where his phone is placed, and nothing else. The mobile phone can make a call to its own phone. At this time, as long as the default call voice is shouted out loudly, the phone will automatically initiate a voice response, make a corresponding response or play a preset response music, enabling the user to quickly find their own voice. Telephone; for example, the mobile phone user can set "call Zhang San" as the call voice sample, and the corresponding response is set to directly call Zhang San's phone, as long as the user shouts "call Zhang San" to his mobile phone, the mobile phone It is very convenient to automatically dial the phone number of Zhang San, especially for those who can't see the keyboard or call the phone address book.

Referring to FIG. 5, a schematic block diagram of an embodiment of a mobile device according to the present invention includes a detection module 51, a lookup module 52, and a response module 53, wherein:

The detecting module 51 is configured to detect a calling voice from the outside;

The calling voice of the outside world is continuously detected by the detecting module 51.

The searching module 52 is configured to: when the calling voice size of the outside world exceeds a preset voice reference value for starting the voice response function, whether there is a calling voice sample that matches the calling voice;

When the external call voice size exceeds the preset voice reference value for starting the voice response function, the search module 52 searches for whether there is a call voice sample matching the call voice, and outputs the query result to the response module 53.

The voice reference value preset here for starting the voice response function is a preset reference value for starting the voice response function, and the reference value can be expressed by voltage or current. When the external call voice size exceeds the preset voice reference value for starting the voice response function, the voice response function is activated, and the search module 52 searches for whether there is a call voice sample matching the call voice.

The response module 53 is configured to perform a pre-stored response operation corresponding to the call voice sample when the lookup module 52 finds a call voice sample that matches the call voice sample.

When there is a call voice sample that matches the call voice, the response module 53 performs a pre-stored response operation corresponding to the call voice sample. The response operation may be to play a pre-stored response voice corresponding to the call voice sample or perform an action corresponding to the call voice sample.

For example, the pre-stored call voice sample is "Dear", and the pre-stored response operation corresponding to the call voice sample is the voice playing "I am here." Then when the external voice is "Dear," the mobile device plays the voice "I am here." The owner of the mobile device can quickly find his mobile device. For example, the pre-stored call voice sample is “calling XXX call”, and the corresponding response operation is to automatically dial XXX. When the external voice is "calling a XXX call", the action of dialing the XXX call is performed.

Referring to FIG. 5, another embodiment of the mobile device of the present invention further includes a first conversion module 54 and a determination module 55, wherein:

The determining module 55 is configured to determine whether the size of the calling voice of the outside world exceeds a preset voice reference value for starting the voice response function;

The determining module 55 is specifically configured to determine whether the measured voltage or the measured current corresponding to the external calling voice exceeds a preset voltage or current for starting the voice response function.

The first conversion module 54 is configured to acquire the external call voice from the detection module 51, and convert the external call voice into a corresponding measurement voltage or measurement current, and send the corresponding measurement voltage or measurement current of the call voice to the determination module 55; In this embodiment, an example is described in which the external calling voice is converted into a corresponding measured voltage.

The first conversion module 54 acquires the calling voice of the outside world, converts the calling voice into a corresponding measurement voltage, and sends the corresponding measurement voltage of the calling voice to the determining module 55 for determination.

The determining module 55 is specifically configured to determine whether the measured voltage corresponding to the calling voice exceeds a preset voltage for starting the voice response function, and outputs the determination result to the searching module 52;

The determining module 55 receives the measured voltage corresponding to the calling voice converted by the first converting module 54 and determines whether the measured voltage corresponding to the calling voice exceeds a preset voltage for starting the voice response function to activate the voice response function. When the measured voltage corresponding to the calling voice exceeds a preset voltage for starting the voice response function to initiate the voice response function, the notification finding module 52 searches for a calling voice sample that matches the calling voice.

Referring to FIG. 5, in another embodiment of the mobile device of the present invention, a second conversion module 56 is further configured to convert the calling voice into a calling voice signal that can be recognized by the mobile device, and specifically, the corresponding voice of the calling voice can be measured. The voltage is converted to a calling voice signal that the mobile device can recognize.

When the determination result of the judgment module 55 is that the measured voltage corresponding to the calling voice exceeds the preset voltage for starting the voice response function, the measurement voltage corresponding to the calling voice is sent to the second conversion module 56. The second conversion module 56 converts the measured voltage corresponding to the calling voice into a calling voice signal recognizable by the mobile device, and outputs the converted calling voice signal to the searching module 52.

The searching module 52 is specifically configured to find whether there is a calling voice sample that matches the calling voice signal. That is, it is found whether there is a call voice sample whose similarity with the voice feature of the calling voice signal reaches a preset similarity, and outputs the search result to the response module 53.

The matching here refers to that the similarity of the speech features of the calling voice signal reaches a preset similarity or above, and the preset similarity is set according to the user's needs, such as 85% or 75%, etc., Make restrictions.

The related settings of the voice response are previously performed on the mobile device by the setting module 57, including the response voice setting corresponding to the calling voice sample and the calling voice sample, and the voice reference value for starting the voice response function. For example, when the mobile device system does not limit the rated voltage for starting the voice response function, a voltage threshold is set as the voice reference value for starting the voice response function. In addition, in the actual application, the setting module 57 can also be used to set or adjust the similarity between the external voice and the preset calling voice sample, and the like.

Please refer to FIG. 8 , which is a circuit diagram of a specific application of an embodiment of a mobile device according to the present invention, which is specifically as follows:

In this embodiment, the mobile device is a mobile phone, and the mobile phone includes a sound pickup circuit 83, a voltage dividing circuit 80, a voltage comparator 81, an A/D conversion circuit 82, and a main chip 84. The memory 85:

The main chip 84 is a specific application of the processor of the mobile device embodiment, and the voltage dividing circuit 80 and the voltage comparator 81 together constitute a specific application of the switching circuit of the mobile device embodiment.

Among them, the sound pickup circuit 83 includes a microphone 801 that detects sound from the outside, and an electrostatic device 802 that converts the external sound into a measured voltage.

The voltage dividing circuit 80 further includes a first resistor 807 and a second resistor 808. The first resistor 807 is connected in series with the second resistor 808. One end of the first resistor 807 is electrically connected to the voltage source, and the other end is electrically connected to one end of the second resistor 808. Connected, the other end of the second resistor 808 is grounded for distributing the voltage from the voltage source; the voltage resistor 81 is connected between the first resistor 807 and the second resistor 808, and the first resistor 807 and the second resistor 808 are simultaneously connected. A voltage is generated between the functions for initiating the voice response function.

The voltage comparator 81 further includes a first port 804 electrically coupled to the voltage dividing circuit 80 between the first resistor 807 and the second resistor 808 for receiving the voltage dividing circuit 80 between the first resistor 807 and the second resistor 808. Generating a voltage for initiating the voice response function and inputting the voltage comparator 81; the second port 803 is electrically connected to one end of the electrostatic device 802 for receiving the measured voltage converted by the external voice and inputting the voltage comparator 81; The port 806 is electrically connected to the main chip 84, and is configured to notify the main chip 84 when the measured voltage exceeds a preset voltage for starting the voice response function, and specifically can notify the main chip 84 by a high level or a low level; The fourth port 805 is electrically connected to the A/D conversion circuit 82 for outputting the measured voltage to the A/D conversion circuit 82 when the measured voltage exceeds a preset voltage for activating the voice response function;

The microphone 801 is electrically connected to one end of the electrostatic device 802, and transmits the detected external voice to the electrostatic device 802. The other end of the electrostatic device 802 is electrically connected to the voltage comparator 81 through the second port 803 to measure the external voice. The voltage is output to the voltage comparator 81.

One end of the A/D conversion circuit 82 is electrically connected to the voltage comparator 81, and the other end is electrically connected to the main chip 84 for converting the measurement voltage into a mobile device when the measured voltage exceeds a preset voltage for starting the voice response function. The identifiable call voice signal is sent to the master chip 84.

A response operation setting corresponding to the calling voice sample and the calling voice sample is stored in the memory 85.

The components work in the following ways:

The microphone 801 of the mobile phone receives the external sound, and after the electrostatic device 802 converts the sound into the measured voltage, the voltage V1 converted by the external sound is input to the voltage comparator 81 via the second port 803 through the electrostatic device 802; the voltage dividing circuit 80 includes the first The two resistors, the resistor 807 and the second resistor 808, are divided by two resistors to generate a voltage V2 between the two resistors, and V2 is used as a voltage for starting the voice response function. V2 is input to the voltage comparator 81 via the first port 804; the voltage comparator 81 compares the voltages V1 and V2, and when V1 is greater than V2, the third port 806 notifies the main chip 84 to perform processing.

The main chip 84 is configured to receive the notification of the third port 806, activate the voice response function, and acquire the calling voice signal from the A/D conversion circuit 82, and look in the memory 85 for whether there is a calling voice that matches the voice feature of the calling voice signal. The sample, when there is a call voice sample matching the calling voice signal, controls the pre-stored response operation corresponding to the calling voice sample.

Through the above method, in the original circuit design of the mobile phone, a voltage dividing circuit and a voltage comparator connected to the voltage dividing circuit are added, that is, the dynamic voice response function of the mobile phone can be realized. In general, the voltage V1 generated when a person utters a call is about 350 mV (about 200 mV when a person speaks). Therefore, when designing a circuit, the voltage V2 generated by the voltage division of the voltage dividing circuit can be controlled to be 350 mV as a voltage for starting the voice response function. Of course, in practical applications, the voltage of the voltage V2 is controlled according to the actual parameters of the microphone. Once the voltage generated by the external voice exceeds the voltage V2 generated by this voltage division, the internal voice response function of the mobile phone is awakened.

On the other hand, when there is no external voice around, the power consumption of the voltage divider circuit can be reduced to 0 by the circuit design; when there is external voice, but the external voice is not enough to wake up the voice response function, the voltage divider circuit consumes only about 0.1. -0.2mA, and this power consumption can be further reduced by circuit optimization design, with little impact on standby. In this way, the external voice strength and weakness are sensed. Only when the voltage after the external voice conversion reaches the preset voltage for starting the voice response function, the main chip is notified to start the voice response function, thereby avoiding the long-time activation of the voice response function. The loss of power makes the phone more user-friendly, more convenient and easier to use. At the same time, the added voltage dividing circuit and the voltage divider are all commonly used components, and the manufacturing cost is low.

With the description of the foregoing embodiments, the present invention has the following advantages over the prior art: on the one hand, the mobile device detects the calling voice from the outside to initiate the following voice feature matching process, thereby enabling the mobile device to perform pre-stored and called voices. The corresponding response operation of the sample, instead of the triggering method in the prior art, makes the use of the mobile device more humanized, more convenient, and easier to use; on the other hand, by sensing the change of external voice strength, only when the external voice is converted When the voltage reaches the preset voltage for starting the voice response function, the wake-up voice response function is controlled to achieve dynamic response, and the power loss caused by the long-time voice response function is avoided, so that the power consumption of the mobile device is lower. Moreover, the response mode of the mobile device in response to the user's call is diversified, giving the user a richer experience.

In addition, the implementation method of the voice response method of the present invention only needs to add a voltage dividing circuit and a voltage comparator on the basis of the original mobile device, and the added voltage dividing circuit and the voltage comparator are commonly used. Parts, low manufacturing costs, and possible implementation are simple. When the external voice is not enough to wake up the voice response function, the part of the circuit hardly works. The power consumption is small, and has no effect on the standby time of the mobile device.
