Referring to FIG. 1 , FIG. 1 is a schematic flowchart of a method for reminding arrival at a station provided by an embodiment of the present application. The arrival reminder method is applied to the electronic device provided by the application, and the electronic device includes a processor, a dedicated speech recognition chip and a microphone. As shown in FIG. 1 , the process of the arrival reminder method provided by the embodiment of the application may be as follows:

In 101, the processor receives an arrival reminder request, and determines a target public transportation station that needs to perform arrival reminder according to the arrival reminder request.

It should be noted that the types of public transportation involved in the following embodiments include but are not limited to subways, buses, and the like.

In this embodiment of the present application, the processor is a processor suitable for general processing tasks, such as a processor of an ARM architecture. Dedicated speech recognition chips are special-purpose chips designed for speech recognition, such as digital signal processing chips designed for speech recognition, application-specific integrated circuit chips designed for speech recognition, etc. The processor, with lower power consumption, is suitable for the processing of speech recognition tasks. Among them, any two of the dedicated speech recognition chip, the processor and the microphone establish a communication connection through a communication bus (such as an I2C bus) to realize data interaction. Specifically, the model of the processor and the model of the dedicated speech recognition chip can be selected by those of ordinary skill in the art according to actual needs. For example, the processor models that can be selected include but are not limited to Snapdragon 855+, Snapdragon 845, Snapdragon 820, Snapdragon 810, and Snapdragon 710.

In addition, the microphone included in the electronic device may be a built-in microphone or an external microphone (which may be a wired microphone or a wireless microphone).

When the electronic device is in a bright screen state, the processor receives an arrival reminder request input by the user. For example, the processor receives the arrival reminder request input by the user through the arrival reminder interface provided by the public transportation application running in the foreground.

Exemplarily, please refer to FIG. 2 , the arrival reminder interface shown in FIG. 2 includes all the public transportation stations that a public transportation route passes through, that is, the public transportation station 1 to the public transportation station 9 shown in the figure. The "alarm clock" control associated with any public transportation station by the user receives an arrival reminder request corresponding to the public transportation station, and the arrival reminder request carries the station identifier (eg, the station name of the station) of the corresponding public transportation station.

After receiving the input arrival reminder request, the processor parses out the site identifier carried in the arrival reminder request, and sets the public transportation station corresponding to the site identifier as the target public transportation station for which arrival reminder is required.

In 102, the target number of public transportation stations that the electronic device needs to pass through to reach the target public transportation station is acquired by the processor.

After determining the target public transportation station that needs to be reminded of arrival, the processor further acquires the target number of the public transportation stations that the electronic device needs to pass through to reach the target public transportation station.

The processor first obtains the base station identifier of the current base station that is currently connected with the electronic device for mobile communication, and determines the public transportation station corresponding to the current base station according to the preset correspondence between the base station identifier and the public transportation station, which is recorded as the current public transportation station. traffic stop.

It should be noted that a base station provides a network access service for an electronic device, and its location is usually fixed. When the electronic device establishes a mobile communication connection with a certain base station, the location of the electronic device can be determined. Based on this, in the embodiment of the present application, the base station is pre-associated with the nearest public transportation station, and the corresponding relationship between the base station identifier and the public transportation station is further established. The base station identifier is used to uniquely characterize the base station, and can be selected as a parameter of the base station identifier by those of ordinary skill in the art according to actual needs.

After determining the current public transportation station, the processor obtains the pre-stored route information from the current public transportation station to the target public transportation station, and determines that the electronic device is connected by the current public transportation station according to the route information, the current public transportation station and the target public transportation station. The target number of public transport stops the station needs to pass through to reach the target public transport stop.

For example, for the public transportation route from public transportation station 1 to public transportation station 9 shown in FIG. 2, assuming that the target public transportation station is public transportation station 9, if the determined current public transportation station is public transportation station 3, the processor may It is determined that the target number of public transport stops that the electronic device needs to pass through to reach the target public transport stop is six.

In 103, the microphone is controlled by a dedicated speech recognition chip to collect external audio signals.

After determining the target number of public transport stations that the electronic device needs to pass through to reach the target public transport station, the processor instructs the dedicated speech recognition chip to start passing station detection, that is, to detect whether to pass the public transport station.

Correspondingly, according to the instructions of the processor, the dedicated speech recognition chip controls the microphone to collect the external audio signal for the detection of passing station.

In 104, the audio signal is recognized by the dedicated speech recognition chip and the processor, and the number of stops where the electronic device has passed the public transportation stops is obtained.

Among them, the dedicated speech recognition chip and processor perform stop-pass detection according to the collected audio signal, that is, to identify whether the collected audio signal is an audio signal passing through a public transportation station, and if so, it is determined that the electronic device passes through a public transportation station. Thereby, the number of stops where the electronic device has passed the public transportation stops can be obtained.

Exemplarily, the dedicated speech recognition chip first identifies whether the audio signal is an audio signal passing through a public transportation station, and when it is recognized that the audio signal is an audio signal passing through a public transportation station, the audio signal is provided to the processor, and the processor is used again. It is identified whether the audio signal is an audio signal passing through a public transportation stop, and if so, it is determined that the electronic device passes through a public transportation stop.

For example, the dedicated speech recognition chip can determine whether the audio signal includes the audio features of the public transportation station, and if so, it can determine that the aforementioned audio signal is an audio signal passing through the public transportation station; and the processor can directly compare the audio signal provided by the microphone with the pre-collected audio signal. The audio signals of the public transportation station are compared, and when the two are consistent, it is determined that the audio signal is the audio signal passing through the public transportation station.

In 105, when the aforementioned number of stations is consistent with the number of target stations, a preset arrival reminder operation is performed by the processor.

Among them, the processor determines in real time whether the number of stations where the electronic device has passed public transportation stations is consistent with the number of target stations. The target public transportation station of the arrival reminder, at this time, the processor executes the preset arrival reminder operation. The types of arrival reminder operations are not specifically limited in the embodiments of the present application, and can be set by those of ordinary skill in the art according to actual needs, including but not limited to arrival reminder methods such as audio, video, image, and text. For example, the processor may play a preset arrival reminder alarm tone, and use the arrival reminder alarm tone to remind the user that he has arrived at the station.

As can be seen from the above, the present application receives the arrival reminder request through the processor, and determines the target public transportation station that needs to be reminded according to the arrival reminder request, and obtains the information of the public transportation station that the electronic device needs to pass through to reach the target public transportation station. The number of target stations, and then control the microphone to collect external audio signals through the special speech recognition chip, and the collected audio signals are recognized by the special speech recognition chip co-processor to obtain the number of stations where the electronic equipment has passed the public transportation station, and finally when the When the number of sites is the same as the number of target sites, a preset arrival reminder operation is performed by the processor. Compared with the related art, the arrival reminder can be realized without satellite positioning, which can effectively reduce the power consumption of the electronic device to realize the arrival reminder.

In one embodiment, the audio signal is recognized by a dedicated speech recognition chip and a processor to obtain the number of stations where the electronic device has passed public transportation stations, including:

(1) Identify whether the audio signal includes the frequency component corresponding to the public transportation station through a dedicated speech recognition chip;

(2) when recognizing that the audio signal includes the aforementioned frequency components, identify by the processor whether the audio signal is a preset audio signal corresponding to a public transportation station;

(3) The number of sites is obtained according to the number of recognition times when the processor's recognition result is yes.

It should be noted that there are specific sound signatures for different types of public transport stops.

For example, for a bus station, when the bus passes through the bus station, there is a sound feature of the door opening/closing (ie, the door opens at the station, and the door closes when leaving the station); for a subway station, when the subway passes the subway station, Then there is the sound feature of the prompt tone of the subway door opening/closing (the same is to open the door at the station and close the door at the departure station).

Illustratively, taking a subway station as an example, please refer to FIG. 3 . FIG. 3 is a spectrogram of the prompt sound when the subway door is opened. According to the spectrogram, it can be seen that the prompt sound of the subway door opening and closing is composed of multiple frequency components. Correspondingly, the correspondence between subway stations and corresponding frequency components can be established in advance. In the same way, the corresponding relationship between public transport stations and corresponding frequency components can be established.

Therefore, when the audio signal is recognized, the dedicated speech recognition chip can recognize whether the audio signal includes the frequency component corresponding to the public transportation station. If so, it can be preliminarily determined that the electronic device has passed a public transportation station, and the audio signal is provided to the processor for further identification by the processor. Wherein, the processor identifies whether the audio signal is a preset audio signal corresponding to a public transportation station, and if so, it can be determined that the electronic device has passed a public transportation station.

Therefore, the processor can obtain the number of stations where the electronic device has passed the public transportation station according to the number of times of recognition that the identification result is yes, wherein the processor can directly use the number of times the identification result is yes as the number of times the electronic device has passed the public transportation station number of sites.

For example, the processor recognizes multiple audio signals provided by the dedicated speech recognition chip at different times. If the number of times the recognition result is yes is N, it means that the number of stations where the electronic device has passed public transportation stations is also N.

In one embodiment, before identifying whether the audio signal includes the frequency component corresponding to the public transportation station by using a dedicated speech recognition chip, the method further includes:

The human voice frequency components in the audio signal are filtered out through a dedicated speech recognition chip.

Wherein, before the audio signal is identified, the human voice frequency components in the audio signal can be extracted and filtered, so as to reduce the interference caused by the human voice frequency components to the identification.

In one embodiment, identifying whether the aforementioned audio signal includes the frequency component corresponding to the public transportation station by using a dedicated speech recognition chip, including:

Whether the duration of the aforementioned frequency component in the aforementioned audio signal reaches a preset duration is identified by a dedicated speech recognition chip, and if yes, it is determined that the aforementioned frequency component is included in the aforementioned audio signal.

In the embodiment of the present application, when recognizing whether the audio signal provided by the microphone includes the frequency component corresponding to the public transportation station, the dedicated speech recognition chip can identify whether the duration of the frequency component corresponding to the public transportation station in the audio signal reaches a preset duration Duration, when it is recognized that the aforementioned frequency components persist in the audio signal for a predetermined duration, it is determined that the audio signal includes frequency components corresponding to the public transportation station.

It should be noted that different types of public transportation stations have different corresponding frequency components.

For example, taking a subway station as an example, it corresponds to 7 different frequency components, these 7 different frequency components correspond to corresponding preset durations, and the preset durations corresponding to different frequency components are different. Whether the durations of the seven frequency components corresponding to the subway station in the audio signal provided by the microphones have reached their respective preset durations, and if they are all reached, it can be determined that the audio signal includes the frequency components corresponding to the subway station, and it can be determined that the electronic device has passed a subway station.

In one embodiment, identifying whether the duration of the aforementioned frequency components in the audio signal reaches a preset duration by using a dedicated speech recognition chip, including:

(1) The above-mentioned audio signal is subjected to non-overlapping framing processing by a dedicated speech recognition chip to obtain a plurality of audio frames;

(2) Fourier transform is performed on the audio frame by a special speech recognition chip, and according to the Fourier transform result, whether the amplitudes of the aforementioned frequency components in the continuous audio frames within the preset duration all reach the preset amplitude, yes Then, it is determined that the duration of the aforementioned frequency component in the aforementioned audio signal reaches a preset duration.

In the embodiment of the present application, when identifying whether the duration of the aforementioned frequency components in the audio signal reaches a preset duration, the dedicated speech recognition chip first performs non-overlapping frame division processing on the audio signal provided by the microphone to obtain multiple audio frames.

For example, please refer to FIG. 4, the dedicated speech recognition chip performs non-overlapping frame division for the audio signal x(n) provided by the microphone, the length of each frame is N, and m audio frames are obtained by dividing the frame into frames, and each audio frame can be expressed as x _m (n). Among them, non-overlapping framing can be generally understood as framing to obtain that there is no overlap between two adjacent audio frames.

After obtaining multiple audio frames by framing, the dedicated speech recognition chip further performs Fourier transform on each audio frame obtained by framing, and identifies the frequency components of the corresponding public transportation stations within a preset time period according to the Fourier transform results. Whether the amplitudes in the consecutive audio frames of the frequency components all reach the preset amplitude, and if so, it is determined that the duration of the frequency component in the audio signal reaches the preset duration. The preset duration can be set by those of ordinary skill in the art according to actual needs, which is not specifically limited in this embodiment of the present application.

其中abs[]表示求取绝对值。对于频率成分f'，若频率成分f'在预设时长t内的连续音频帧每帧的幅值

均达到预设幅值α时，则确定频率成分f'在音频信号中的持续时长达到预设时长t。For example, perform fast Fourier transform on the audio frame x _m (n) to obtain the corresponding Fourier transform result X _m (n)=FFT[x _m (n)], then the frequency resolution of the Fourier transform is f _s /N, where f _s is the sampling frequency of the audio signal, and N is the length of the audio frame. For any frequency component f, its position in the Fourier transform result X _m (n) is i=Nf/f _s , which can be expressed as X _m (i). Then, for the frequency component f' of the corresponding public transportation station, in each audio frame, the amplitude of the frequency component f' is

Where abs[] means to find the absolute value. For the frequency component f', if the frequency component f' is within the preset duration t, the amplitude of each frame of consecutive audio frames

When both reach the preset amplitude α, it is determined that the duration of the frequency component f' in the audio signal reaches the preset duration t.

In one embodiment, identifying by the processor whether the audio signal is a preset audio signal corresponding to a public transportation station includes:

(1) calling the pre-trained audio recognition model corresponding to the preset audio signal by the processor;

(2) Identifying whether the audio signal is a preset audio signal corresponding to a public transportation station according to the audio recognition model.

It should be noted that, in the embodiment of the present application, an audio recognition model corresponding to a preset audio signal is pre-trained, and it is configured to classify the input audio signal to be recognized to obtain a classification of the audio signal to be recognized as the preset audio signal. As a result, or a classification result that the audio signal to be identified is not the preset audio signal is obtained.

Exemplarily, preset audio signals corresponding to public transport stations may be collected in advance, and the spectrograms thereof may be extracted as training samples, and a convolutional neural network may be used for training according to the training samples to obtain an audio recognition model.

Correspondingly, when the processor identifies whether the audio signal is the preset audio signal corresponding to the public transportation station, the processor can call the pre-trained audio recognition model corresponding to the preset audio signal, and use the audio provided by the special speech recognition chip. The signal is input into the audio recognition model for classification, and the recognition result that the audio signal is the aforementioned preset audio signal is obtained, or the recognition result that the audio signal is not the aforementioned preset audio signal is obtained.

In one embodiment, receiving a station reminder request by the processor includes:

(2) According to the preset correspondence between the base station identifier and the public transportation station, determine the public transportation station corresponding to the base station identifier through the processor;

(3) When the aforementioned public transportation station is the target public transportation station, a preset arrival reminder operation is performed by the processor.

In the embodiment of the present application, when the processor recognizes that the number of stations that the electronic device has passed through the public transportation station is the same as the number of target stations, it does not immediately execute the preset arrival reminder operation, but firstly informs the public transportation station that the electronic device actually arrives at. The traffic station is identified, and the preset arrival reminder operation is performed only when the public transport station actually reached by the electronic device is consistent with the target public transport station.

Wherein, when it is recognized that the number of stations where the electronic device has passed the public transportation station is consistent with the number of target stations, the processor first obtains the base station identifier of the base station that establishes a mobile communication connection with the electronic device, that is, obtains the network for the electronic device.
