Embodiment one
Figure 1 shows that the process flow diagram of a kind of information processing method that the embodiment of the present invention provides, described method is applied to an electronic equipment, comprising:
S101, electronic equipment obtain recording request instruction, enable audio collecting device according to described recording request instruction.
The explanation of value be, user is when using different application to record, the operation carried out may be different, and such as, it may be the Home key double-clicking electronic equipment that user wakes the operation that voice assistant carries out up, and when carrying out micro-letter voice, may be long by record button, that is, electronic equipment can call in response to the recording of different application based on user operation, get described recording request instruction, and enable described audio collecting device according to described recording request instruction.
S102, obtain the first acoustic information of the preset duration that described audio collecting device collects, and obtain the first audio frequency parameter based on described first acoustic information.
It should be noted that, described first acoustic information be described electronic equipment before actual recording, the prescoring of acquisition, described electronic equipment can not using described first acoustic information as final recorded message.But owing to experiencing for user, electronic equipment is after enabling audio collecting device, the actual recording carried out immediately, and therefore, in order to avoid omitting too much voice messaging, in specific implementation process, this preset duration should be short as far as possible.In the preferred implementation of the one of the embodiment of the present invention, this preset duration was no longer than 0.2 second.
Further, electronic equipment, after getting described first acoustic information, obtains the first audio frequency parameter based on described first acoustic information, and described first audio frequency parameter is for configuring described audio collecting device.
In a kind of possible implementation of the embodiment of the present invention, described electronic equipment obtains the first audio frequency parameter based on described first acoustic information and specifically comprises:
Described first acoustic information resolved by described electronic equipment, obtains the energy of described first acoustic information; Based on the energy of described first acoustic information, determine that described audio collecting device gathers the first gain parameter of sound, wherein, described first audio frequency parameter comprises described first gain parameter.
It should be noted that, the gain parameter of audio collecting device is relevant to the energy of the sound that described audio collecting device collects, and described energy can be the decibel value of sound.
Illustratively, according in specific implementation process, user is for the demand of acoustic energy, the energy range of sound collection can be pre-set, such as, the sound that user is in 40 to 60 for decibel value has good auditory perception, then the decibel value scope that can preset described first acoustic information is [40,60].Like this, electronic equipment is after getting described first acoustic information, resolve the decibel value obtaining described first acoustic information, if the decibel value of described first acoustic information is not within default described decibel value scope, then described electronic equipment can regulate the gain parameter of described audio collecting device, the decibel value of described first acoustic information is within described default decibel value scope, and the first gain parameter when gain parameter being now defined as described audio collecting device actual recording.
Such as, for micro-letter voice, because user very closely sends speech message apart from Mike usually, now, the energy of described first acoustic information that described electronic equipment gets may be excessive, causes the discomfort of user's sense of hearing, therefore, described electronic equipment when determining that the energy of described first acoustic information exceedes default energy range, can reduce the gain parameter of audio collecting device, reduces the energy gathering sound.And shake TV during micro-letter is shaken, because recording distance may arrive number meter Yuan, now, electronic equipment can when determining that the energy of described first acoustic information is less than preset energy value, increase the gain parameter of described audio collecting device, thus increase the energy of the sound that described audio collecting device collects.
In the implementation that the another kind of the embodiment of the present invention is possible, described electronic equipment obtains the first audio frequency parameter based on described first acoustic information and also comprises:
Described first acoustic information resolved by electronic equipment, obtains the noise information in described first acoustic information; Resolve the frequency spectrum of described noise information, the frequency spectrum of wherein said noise information is used for utilizing noise information described in wave filter filtering in described audio collecting device, and described first audio frequency parameter comprises the frequency spectrum of described noise information.

Above-mentionedly just to illustrate; electronic equipment can also according to described first acoustic information; get other audio frequency parameter; the present invention will not enumerate; other audio frequency parameters got by this first acoustic information that those skilled in the art can expect, also should be belonged within protection scope of the present invention.
In addition, in the optional implementation of the one of the embodiment of the present invention, described electronic equipment can also detect described electronic equipment and whether there is outer playback frequently; If there is described outer playback frequently, then determine the filtering parameter of echo cancellation filter, wherein, described audio collecting device comprises described echo cancellation filter, described echo cancellation filter is for filtering playback except as noted frequently, and described first audio frequency parameter comprises the filtering parameter of described echo cancellation filter.
Illustratively, if there is audio external play device in described electronic equipment, then this electronic equipment is before the described audio collecting device of configuration, detect described audio external play device and whether there is outer playback frequently, if described audio external play device exists outer playback frequently, then described electronic equipment can determine the echo cancellation algorithm enabling described audio collecting device.
Further, electronic equipment is after determining to enable echo cancellation algorithm, frequently the filtering parameter of echo cancellation filter can be determined by described first acoustic information and described outer playback, if the duration of described first acoustic information is too short, electronic equipment cannot determine the filtering parameter of effective echo cancellation filter, now, described electronic equipment also can determine the filtering parameter adopting the echo cancellation filter given tacit consent in this echo cancellation algorithm, the sound of described outer playback frequency and the collection of described audio collecting device is constantly restrained by echo cancellation filter, avoid occurring echo.
S103, configure described audio collecting device based on described first audio frequency parameter.
Particularly, with reference to the above-mentioned specific descriptions to step S102, described first acoustic information resolved by electronic equipment, by the energy to the first acoustic information, the analysis of noise spectrum etc. can determine the gain parameter of audio collecting device, the audio frequency parameters such as filter parameter, therefore, described electronic equipment obtains after described first audio frequency parameter through above-mentioned steps S103, utilizes described first audio frequency parameter to configure described audio collecting device.

Wherein, described second acoustic information is described electronic equipment after the described audio collecting device of configuration, before receiving recording command for stopping in this period of time, utilizes the acoustic information that described audio collecting device collects to described electronic equipment.
What deserves to be explained is, for certain some audio frequency parameter, electronic equipment can regulate in real time in Recording Process, such as, filter parameter in noise cancelling alorithm, because environmental noise is change, therefore filter parameter also constantly updates change in sound collection process, in addition, if there is described outer playback frequently, described electronic equipment can also carry out time synchronized based on the sound of described outer playback frequency and described audio collecting device collection, adjust the filtering parameter of described echo cancellation filter, and the described audio collecting device after utilizing filtering parameter to adjust gathers sound, obtain described second acoustic information.
But for other audio frequency parameters, electronic equipment carries out calculating needs longer delay time, such as, many Mikes strengthen the directed recording parameter in algorithm, for this type of audio frequency parameter, electronic equipment can complete calculating in this Recording Process, and upper once record time use.
Therefore, in a kind of possible implementation of the embodiment of the present invention, described electronic equipment is after getting described second acoustic information, the second audio frequency parameter is determined based on described second acoustic information, wherein, described second audio frequency parameter for configure described audio collecting device next time receive recording request instruction record time parameter.

It should be noted that, when the energy of noise information is not less than the energy of voice messaging, the noise cancelling alorithm of audio collecting device cannot effectively abate the noise, now, electronic equipment can be enabled many Mikes and strengthen algorithm, by detecting the position of sound source, orientation recording is carried out for sound source, because electronic equipment detects sound source position, and the parameter calculating directed recording needs the longer time, therefore, described electronic equipment can next time enable described audio collecting device carry out sound collection time, the directed recording parameter calculated is utilized to configure described audio collection parameter.
Based on described second acoustic information, described electronic equipment determines that the second audio frequency parameter can also comprise:
Described electronic equipment obtains the energy of described second acoustic information the second acoustic information after treatment; Based on the energy of described second acoustic information, determine that described audio collecting device gathers the second gain parameter of sound, wherein, described second audio frequency parameter comprises described second gain parameter.
Particularly, the sound that described audio collecting device collects according to described first gain parameter, after noise elimination and/or echo cancellor, its energy can reduce, like this, although the energy of the sound that described audio collecting device collects according to described first gain parameter is in default energy range, but after generation energy abatement, the energy of described second acoustic information may not be in default energy range, that is, the decibel value of described second acoustic information may be less than normal, have impact on recording effect, therefore, described electronic equipment can after described second acoustic information of acquisition, the second gain parameter of described audio collecting device is determined further according to the energy of described second acoustic information, to ensure that described audio collecting device gathers acoustic information according to described second gain in next time,
Above-mentionedly just to illustrate; electronic equipment can also according to described second acoustic information; get other the second audio frequency parameter; the present invention will not enumerate; other audio frequency parameters got by this second acoustic information that those skilled in the art can expect, also should be belonged within protection scope of the present invention.
Further, electronic equipment is after getting described second audio frequency parameter, when enabling described audio collecting device next time, described second audio frequency parameter is utilized to configure described audio collecting device, so that described audio collecting device can obtain than the better recording effect of described second acoustic information based on described second audio frequency parameter.
It should be noted that, described electronic equipment may repeatedly enable described audio collecting device within the of short duration time, such as, user repeatedly sends micro-letter voice at short notice, in this case, described electronic equipment can only when first time enables described audio collecting device, described first acoustic information is obtained based on described audio collecting device, described audio collecting device is enabled at least one time afterwards, described electronic equipment can keep the audio frequency parameter of audio collecting device constant, or described audio collecting device can be configured according to described second audio frequency parameter.
Particularly, described electronic equipment can after enabling described audio collecting device at every turn, start timing, if electronic equipment is in preset time range, again enable described audio collecting device, the audio frequency parameter of described audio collecting device then can be kept constant, or configure described audio collecting device according to described second audio frequency parameter; If described electronic equipment exceedes described time range, again enable described audio collecting device, then described electronic equipment obtains the first acoustic information based on described audio collecting device again, and obtain the first audio frequency parameter based on described first acoustic information, configure described audio collecting device based on described first audio frequency parameter.
Above-mentionedly just to illustrate, such as, described electronic equipment can also obtain the mark of the application program calling recording each time, if in preset time range, according to the mark of application program, described electronic equipment determines that same application repeatedly calls described audio collecting device, then described electronic equipment can only when first time enables described audio collecting device, described first acoustic information is obtained based on described audio collecting device, described audio collecting device is enabled at least one time afterwards, described electronic equipment can keep the audio frequency parameter of audio collecting device constant, or described audio collecting device can be configured according to described second audio frequency parameter.The present invention does not limit this.
