In order to be better understood from technique scheme, below in conjunction with Figure of description and specific embodiment, technique scheme is described in detail.
Embodiment one
By the application embodiment, it is provided that a kind of information processing method, it is applied among electronic equipment, here electronic equipment can be earphone, can also being that mobile phone, panel computer etc. can pass through to be wired or wirelessly connected to the electronic equipment of earphone, at this, just differing one schematically illustrates.In specific descriptions below, it is described in detail for mobile phone.
Refer to Fig. 1, the embodiment of the present application provides a kind of information processing method, is applied among electronic equipment, and described method includes:
S101: gather described electronic equipment the first audio-frequency information in the environment；
S102: judge that whether the first parameter of described first audio-frequency information is more than a values, it is thus achieved that the first judged result；
S103: if described first judged result is yes, performs the first operation, so that the user of described electronic equipment obtains prompting.
Refer to Fig. 2, in the embodiment of the present application, step S102: judge that whether the first parameter of described first audio-frequency information is more than a values, it is thus achieved that the first judged result, particularly as follows:
S201: judge that whether the frequency of the first audio-frequency information is more than the first values, it is thus achieved that the first sub-judged result；
S202: judge that whether the loudness of the first audio-frequency information is more than the second values, it is thus achieved that the second sub-judged result；
S203: based on described first sub-judged result and described second sub-judged result, it is judged that whether the first parameter of described first audio-frequency information is more than the first values, it is thus achieved that the first judged result；
Wherein, if described first sub-judged result and described second sub-judged result are for being, it was shown that described first judged result is yes, it was shown that the first parameter of described first audio-frequency information is more than the first values.
Assume that user has on bluetooth earphone and plays the music A in mobile phone, mobile phone is now to perform to play the task of music, while the sound gathered in current environment, assume that the voice data collected is B (t), it is saved in the memory element in mobile phone, here memory element can be audio data buffer, it is also possible to for the memorizer of sequential core-pulling, it is also possible to be the memorizer of link storage organization or for other the memory element of form.The form of the first audio-frequency information here can be MP3 format, WMA form, ASF form etc., is not specifically limited in this application.
It follows that perform step S102, the first parameter contains frequency and loudness, it is assumed that default frequency values and loudness value scope are as shown in the table:
| Frequency (Hz) | 200-2000 |
| Loudness (dB) | 0-60 |
Table one
nullThen above embodiment，Consider the environment at user place，The first situation，Assume before time tl and t1 user be in a quiet environment，Such as user has on earphone and takes a walk in park，Assume that the voice data collected in the t1 moment is B (t1)，Mobile phone continues to gather the voice data in environment，Assume in the t2 moment，The road of distance users side is sailed a car，Car is blown a whistle and is reminded people around to take care，Duration of blowing a whistle is 0.1s，Now，It is B (t2+0.1) that mobile phone collects voice data now，In the data of the ambient sound B (t2+0.1) gathered，Judge that whether the frequency of this section of acoustic signals is more than the first values，And judge that whether the loudness of this section of acoustic signals is more than the second values，Namely judge whether frequency values and the loudness value of the first audio signal gathered between t2 moment and t2+0.1s moment sudden change occur，Here the first values and the second values can be adjusted according to the needs of those skilled in the art，It is not specifically limited in this application.The false frequency values preset as shown in Table 1 ranges for 200Hz-2000Hz, the loudness value scope 0dB-60dB preset, and it is assumed that car is at distance users 200m place, the car of mobile phone collection blows a whistle sound frequency value scope at 500Hz-800Hz, car sound intensity value of blowing a whistle is 50dB, it can thus be appreciated that, car blows a whistle sound frequency value within the scope of default frequency values 200Hz-2000Hz, car blows a whistle the loudness value of sound in default loudness value 0dB-60dB, so, the first judged result obtained is no, show that the first parameter value of the first audio-frequency information collected is not less than values.When car continues to user's direction running, when distance users 100m place, the car of mobile phone collection blows a whistle sound frequency value scope at 500Hz-800Hz, loudness value 80dB, it follows that car is blown a whistle, sound frequency value is not less than default frequency values, but car is blown a whistle, sound intensity value has exceeded the maximum 60dB of the loudness value preset, so, it is thus achieved that the first judged result be yes, it was shown that the first parameter value of the first audio-frequency information collected has exceeded values.
Then, performing step S103: if described first judged result is yes, perform the first operation, the process of implementing has three kinds of modes:
First kind of way: if described first judged result is yes, by the audio playing unit of described first audio-frequency information output to described electronic equipment.
The second way: if described first judged result is yes, audio playing unit by described first preset audio information or the second audio-frequency information output extremely described electronic equipment different from described first audio-frequency information, wherein, described first preset audio information or described second audio-frequency information are for pointing out the user of described electronic equipment to should be noted that safety；And/or generate and export the first Word message at the display unit of described electronic equipment, wherein, described first Word message is used for pointing out described user to should be noted that safety.
Refer to Fig. 3, Fig. 4 and Fig. 5, the third mode includes step:
S301: if described first judged result is for being, detect whether described electronic equipment is in audio frequency broadcast state, it is thus achieved that the 3rd judged result；
S302: if described 3rd judged result is for being, generate and perform the first control instruction, switches to stopping broadcast state from described audio frequency broadcast state controlling described electronic equipment.
After electronic equipment is in stopping broadcast state, further comprise the steps of:
S401: detection obtains the first operation being in described audio frequency broadcast state for controlling described electronic equipment；
S402: respond described first operation, control described electronic equipment and switch to described audio frequency broadcast state from described stopping broadcast state；Or
S501: judge that whether the current time of described electronic equipment and described electronic equipment enter the first duration between the described stopping broadcast state moment more than the second preset duration, it is thus achieved that the 4th judged result；
S502: if described 4th judged result is for being, generate and perform the second control instruction, switches to described audio frequency broadcast state from described stopping broadcast state controlling described electronic equipment.
In specific implementation process, continue the example above and say, in acquisition the first judged result for after being, the mode performing the first operation has three kinds, and first kind of way is by the audio playing unit of the first audio-frequency information output extremely described electronic equipment collected, such as when user utilizes mobile phone and music listened by earphone, mobile phone collects the sound of blowing a whistle of car, sound of being blown a whistle by the car collected exports in earphone, and now, user can hear the sound of blowing a whistle of car while listening music；The second way is by the second different for sound of blowing a whistle from car audio-frequency informations, such as the prompt tone " please noting safety " preset exports in earphone, now, the screen of mobile phone can also show related text information simultaneously, or adopt the prompting mode prompting user such as mobile phone vibrations to should be noted that safety；The third mode is for whether detection mobile phone is currently in audio frequency broadcast state, when mobile phone is in audio frequency broadcast state, generate and perform a control instruction, audio playing unit is allowed to be in stopping broadcast state, now, the music that user is listening stops playing, thus, user can directly hear the ambient sound in the external world.By any one mode in three kinds of modes, user is appreciated that the just past direction running near oneself of car, and therefore, user selects actively to dodge car, and then ensure that user's safety when using mobile phone and earphone to listen music.
Under a third procedure, also include that mobile phone is in stopping broadcast state in the particular embodiment and revert to audio frequency broadcast state, specifically include two ways, first kind of way is that user clicks the button performing audio frequency broadcasting in mobile phone, making mobile phone continue to play music, user can continue through earphone and listen music；The second way is obtain to stop the moment playing music the first duration to current time at mobile phone, assume that the first duration is 1min, judge whether the first duration has exceeded a preset duration, it is assumed that the first preset duration is 59s, it can thus be appreciated that, first duration has exceeded the first preset duration, mobile phone generates and performs the second control instruction, makes mobile phone switch to audio frequency broadcast state from stopping broadcast state, and then, mobile phone continues to play music, and user can continue through earphone and listen music.
Further, in order to adapt to the needs of different scene, obtaining the early warning effect of higher level, also to when the first judged result obtained is no in the application, the frequency values of the first audio-frequency information namely collected and loudness value have carried out process and the analysis of audio-frequency information not less than the situation of values.
Refer to Fig. 6, after performing step S102, also include step S104: when described first judged result is no, it is judged that whether described first audio-frequency information has the first preset audio information, it is thus achieved that the second judged result；
S105: if described second judged result is for being, performs described first operation, so that the user of described electronic equipment obtains prompting.
Refer to Fig. 7, in step S104, when described first judged result is no, it is judged that whether described first audio-frequency information has the first preset audio information, it is thus achieved that the second judged result, include in specific implementation process:
S701: judge that whether the characteristic parameter of the described first audio-frequency information similarity with the default characteristic parameter of described first preset audio information is more than the 3rd preset value, it is thus achieved that the second judged result；
S702: if described second judged result is for being, it was shown that there is in described first audio-frequency information described first preset audio information.
Wherein, described characteristic parameter at least includes: linear predictor coefficient, short-time energy value and short-time zero-crossing rate.
Such as, it is in a noisy environment in the t1 moment to t2 moment user, such as user has on earphone and walks on road, mobile phone collection to the first voice data in the sound that comprises sufficiently complex, wherein, comprise the sound of multiple sounding body, such as the sound of blowing a whistle of various vehicle, the noise in construction site, voice of people etc., in the t1 moment to t2 moment, one ambulance is about to the road by user place, ambulance speed has reached 120km/h, but the sound frequency that now ambulance is blown a whistle and loudness value are all not less than the frequency values scope preset in mobile phone and loudness value scope, namely above-mentioned first judged result is no.Now, if user dodges not in time, to oneself causing danger, and the timely treatment of the wounded in ambulance will can be hindered.
The embodiment of the present application is in implementation process, after performing step S102, performs step S103: when described first judged result is no, it is judged that whether have the first preset audio information in described first audio-frequency information, it is thus achieved that the second judged result.Here the first preset audio information is the special sound that the user trained is frequently run onto in the environment, such as the sound of warning, being such as alarm song, the tucket of vehicle, explosive sound, it is also possible to for the voice of the people that user specifies, here just differing one schematically illustrates.The first preset audio information in the embodiment of the present application can be sound that off-line training is good or certain sound that user oneself assert, it is stored in the solid-state storage region of electronic equipment, high in the clouds can also be stored in, and the needs according to user are updated periodically.
Continue the example above, it is assumed that the Wave data of the first audio frequency collected in the t1 moment to t2 moment is C (t1), wherein, contains the sound waveform data that ambulance is blown a whistle in the first voice data.After the first voice data preserves with file (.wav) form of waveform, needing the first voice data collected is that C (t1) carries out sub-frame processing by certain time length, such as the first audio signal that will collect, per second it is divided into 50 frames, then each frame duration is 20ms, each frame duration can be limited by certain those skilled in the art as required, and before sub-frame processing, the Wave data C (t1) of the first audio frequency collected can be carried out preemphasis by those skilled in the art as required, the HFS of the first voice data is promoted, the frequency spectrum making signal becomes smooth, improve signal to noise ratio.After sub-frame processing, it is possible to the first voice data is carried out windowing process.Next, according to the analysis and processing method to audio signal, the audio frequency characteristics parameter of each frame is analyzed, the process means adopted in the embodiment of the present application include frequency domain facture and Time Domain Processing method, and the feature of extraction and analysis at least includes: linear predictor coefficient (LPCC), short-time energy and short-time zero-crossing rate.
Linear predictor coefficient has reacted the acoustic characteristic of sound channel, it is possible to understand that be that the sampling of an audio frequency can be approached by the linear combination of several audio sample of past.By the signal gathered is carried out Fourier transformation, the logarithm of delivery, then carry out inverse Fourier transform and obtain linear predictor coefficient.
Short-time energy value is in each frame duration, the energy value of the signal of n-th frame, utilizes short-time energy value can distinguish voiced sound and sore throat relieving from sound, and during voiced sound, short-time energy value is bigger than schwa big short-time energy value.
Short-time zero-crossing rate is in each frame duration, the signal waveform number of times by null value.During voiced sound, energy is several in lower frequency section, has relatively low short-time zero-crossing rate, and during schwa, energy concentrates in upper frequency section, has higher short-time zero-crossing rate.
Certain those skilled in the art can adopt frequency domain analysis and a kind of method in temporal analysis as required, and relate to other audio frequency characteristics parameters of extraction, such as, pitch period, Mel frequency cepstral coefficient (MFCC) etc. are analyzed, and just differing at this one schematically illustrates.
nullThose skilled in the art can be arranged as required to the weighted value utilizing different characteristic parameter for specific sound and ambient sound make a distinction identification，Such as，The weight of linear predictor coefficient is 60%，The weight of short-time energy value be 20% and the weight of short-time zero-crossing rate be 10%，The linear predictor coefficient similarity assuming the sound of blowing a whistle of the one section of ambulance trained in the linear predictor coefficient of 500 frame voice datas and mobile phone in the first voice data now collected is 90%，The energy value similarity of the one section of sound of blowing a whistle trained in 500 frame voice data energy values and mobile phone in the first voice data is 60%，The short-time zero-crossing rate similarity of the one section of sound of blowing a whistle trained in the short-time zero-crossing rate of 500 frame voice datas and mobile phone in the first voice data is 60%，It can thus be appreciated that，The similarity ratio value obtained by different characteristic parameter is 78%，Assume that the 3rd presets when being set to 50%，Then the second judged result is yes，Show the sound of blowing a whistle in the first audio-frequency information gathered with ambulance.Certain those skilled in the art as required, can also arrange the weighted value of certain audio frequency characteristics parameter a kind of and adjust the scope of the 3rd preset value, is not specifically limited in this application.
Then, performing step S302: if described second judged result is yes, perform described first operation, the process of implementing has three kinds of modes to describe in the above example, is here just no longer repeated describing.By any one mode in three kinds of modes, user is when learning that ambulance travels to the position at oneself place with speed soon, the more time can be reserved dodge to user, therefore, user can dodge ambulance in time, and then ensure that user's safety when using mobile phone and earphone to listen music.
Embodiment two
