Patent Application
20150074524
Information handling devices (“devices”), for example laptop and desktop computers, smart phones, e-readers, etc., are often used in a context where virtual assistant is available. An example of a virtual assistant is the SIRI application. SIRI is a registered trademark of Apple Inc. in the United States and/or other countries.
A virtual assistant may perform many functions for a user, e.g., executing search queries in response to voice commands. Users often “wake” the virtual assistant by way of an input, e.g., audibly saying the virtual assistant's “name”. Thus, a virtual assistant is activated by a user and thereafter may respond to queries presented by the user.
In summary, one aspect provides a method, comprising: operating an audio receiver and a memory of an information handling device to store audio; receiving input activating a virtual assistant of the information handling device; and after activation of the virtual assistant, processing the audio stored to identify one or more actionable items for the virtual assistant.
Another aspect provides an information handling device, comprising: an audio receiver; one or more processors; and a memory device accessible to the one or more processors and storing code executable by the one or more processors to: operate the audio receiver and a memory to store audio; receive input activating a virtual assistant of the information handling device; and after activation of the virtual assistant, process the audio stored to identify one or more actionable items for the virtual assistant.
A further aspect provides a program product, comprising: a storage device having computer readable program code stored therewith, the computer readable program code comprising: computer readable program code configured to operate an audio receiver and a memory of an information handling device to store audio; computer readable program code configured to receive input activating a virtual assistant of the information handling device; and computer readable program code configured to, after activation of the virtual assistant, process the audio stored to identify one or more actionable items for the virtual assistant.
The foregoing is a summary and thus may contain simplifications, generalizations, and omissions of detail; consequently, those skilled in the art will appreciate that the summary is illustrative only and is not intended to be in any way limiting.
For a better understanding of the embodiments, together with other and further features and advantages thereof, reference is made to the following description, taken in conjunction with the accompanying drawings. The scope of the invention will be pointed out in the appended claims.
It will be readily understood that the components of the embodiments, as generally described and illustrated in the figures herein, may be arranged and designed in a wide variety of different configurations in addition to the described example embodiments. Thus, the following more detailed description of the example embodiments, as represented in the figures, is not intended to limit the scope of the embodiments, as claimed, but is merely representative of example embodiments.
Reference throughout this specification to “one embodiment” or “an embodiment” (or the like) means that a particular feature, structure, or characteristic described in connection with the embodiment is included in at least one embodiment. Thus, the appearance of the phrases “in one embodiment” or “in an embodiment” or the like in various places throughout this specification are not necessarily all referring to the same embodiment.
Furthermore, the described features, structures, or characteristics may be combined in any suitable manner in one or more embodiments. In the following description, numerous specific details are provided to give a thorough understanding of embodiments. One skilled in the relevant art will recognize, however, that the various embodiments can be practiced without one or more of the specific details, or with other methods, components, materials, et cetera. In other instances, well known structures, materials, or operations are not shown or described in detail to avoid obfuscation.
One of the current problems with virtual assistants (VA) is that they cannot be “always on” due to power consumption limits. So when a query or command for the VA happens in conversation with others, the query or command (“action item”) needs to be restated to the VA after waking the VA up, e.g., by stating the VA's name or providing another activating input. In other words, currently virtual assistants are not “always on” but rather are activated, at which point (i.e., thereafter) a query or command may be issued to the VA for processing and execution of a related action.
Accordingly, an embodiment implements a buffering mechanism for an audio receiver, e.g., an on-board microphone. A predetermined amount of audio is stored, e.g., the last “x” seconds of audio data, such that a running buffer of audio data is continuously available. For example, the buffer or memory storing the audio data may be thought of as a running or circular buffer. Thus, when the VA is activated or triggered, it can process the buffer contents looking for action items (e.g., audio data previously associated or keyed to queries or commands). In an embodiment, the mechanism may be read from (e.g., by the application processor after waking up the VA) and written to (e.g., as the microphone collected audio data continues to come in) at the same time.
The illustrated example embodiments will be best understood by reference to the figures. The following description is intended only by way of example, and simply illustrates certain example embodiments.
Referring to
There are power management chip(s) 230, e.g., a battery management unit, BMU, which manage power as supplied for example via a rechargeable battery 240, which may be recharged by a connection to a power source (not shown). In at least one design, a single chip, such as 210, is used to supply BIOS like functionality and DRAM memory.
System 200 typically includes one or more of a WWAN transceiver 250 and a WLAN transceiver 260 for connecting to various networks, such as telecommunications networks and wireless base stations. Commonly, system 200 will include a touch screen 270 for data input and display. System 200 also typically includes various memory devices, for example flash memory 280 and SDRAM 290.

In
The system, upon power on, may be configured to execute boot code 190 for the BIOS 168, as stored within the SPI Flash 166, and thereafter processes data under the control of one or more operating systems and application software (for example, stored in system memory 140). An operating system may be stored in any of a variety of locations and accessed, for example, according to instructions of the BIOS 168. As described herein, a device may include fewer or more features than shown in the system of
Information handling devices, as for example outlined in
As described herein, an embodiment implements a buffering mechanism to collect a predetermined amount of audio, where the amount of predetermined audio stored may be modified, e.g., according to various factor(s). Thus, rather than having to repeat audio that contained an action item (e.g., a query or command) spoken prior to activating the VA, according to an embodiment when the VA is activated or triggered, it can process the buffer contents looking for action items (e.g., audio data previously associated or keyed to queries or commands). This avoids unnecessary repetition of commands and queries to the VA.
In
Thus, the buffering mechanism may operate in a low power or always on mode or a threshold may be implemented at 320 to only record into the buffer when there is detectable microphone activity; that is, to not waste power recording silence. Examples of techniques that may accomplish this are instantaneous power or crest factor threshold detection. Because the contents of the buffer may be fragmented in time (e.g., with periods of silence between periods of activity/recording), the contents may be time-stamped or otherwise processed to ensure appropriate management of the buffer contents.
In an embodiment, the predetermined amount of audio stored at 330 may be varied according to various factor(s). For example, the length of the buffer may vary dynamically by the context encountered. Thus, if a particularly lengthy discussion is taking place, the buffer may be made longer automatically to capture additional audio. Also, the length of the buffer may be reduced according to various factor(s). Some reasons for not using the full memory capacity of the buffer all the time or reducing the size of the buffer would be: power consumption, processing delay after triggering, and privacy concerns, etc.
As part of the monitoring of the ambient audio to detect audio at 320, a determination may be made as to whether a VA has been activated at 340. The VA may be activated in a variety of ways, for example via use of audio input data, e.g., speaking the VA's “name” or other predetermined word or phrase. Additionally, an embodiment may use other detected input, e.g., a discreet gesture or tapping pattern, as a VA activation trigger sensed at 340. For example, instead of talking to his or her VA, a user could give a signal to activate the VA and/or to process the audio buffer at 350 with a tap gesture while the device, e.g., phone, was still in the user's pocket. Notably, the user may activate the VA with or without processing stored audio.
In addition to always processing the stored audio on VA activation, an embodiment may selectively process the stored audio on VA activation. For example, an embodiment may utilize as part of the triggering analysis for processing of the buffer contents use of a unique symbol, e.g., a handwritten symbol sensed by a touch sensitive surface. For example, drawing a star symbol, a common note-taking symbol to indicate a key point, may trigger the buffer to be transcribed. Further actions, as described herein, may automatically flow from this, such as saving the stored audio as transcribed text as an action executed at 370. For example, this might be done in a meeting as a supplement to the user's own notes.
In an embodiment, the trigger mechanism of 340 for activating the VA and processing the stored audio in the buffer (to identify actionable items at 350) may include the use of key word(s) or phrase(s) associated with VA activation and or indications to search the stored audio content. For example, use of pronouns like “that” may be pre-associated with or keyed to an action of searching the buffer contents for actionable items. For example, if the following audio received: User A: “User B, will you pick up some milk on the way home today?”; User B: “Smartphone, remind me about that”, an embodiment may perform the following.
Upon VA wake-up at 340 by the “Smartphone” keyword, the command to “remind me about that” tells the VA to process the microphone buffer looking for candidates for actionable items, in this case a reminder, e.g., a candidate for a calendar entry, containing words or phrases indicative of who (“you”), what (“pick up milk”), when (“on the way home today”), and/or where. Thus, an embodiment may utilize initial commands received by a VA to help identify actionable items stored in buffered audio and thereafter executing actions at 370 based on the actionable items identified at 360. Similarly, other actions may be executed at 370. Some non-limiting examples include transferring the raw audio data to another location, transcribing the audio into text and transferring the transcribed text to another application, e.g., a calendar entry, and initiating higher-level processing, e.g., speech analysis, speaker identification, etc. of stored audio and correlation with device contacts, etc.
Therefore, an embodiment may ascertain a trigger or symbol waking or activating the VA at 340 and process the stored audio to identify actionable items automatically at 350. After identifying actionable item(s) at 360, an embodiment may take or execute additional actions at 370, e.g., automatically preparing a calendar entry, adding a reminder to a to-do list, executing a search based on a query identified in the stored audio, etc.
By storing audio content on a rolling basis, noting that the amount of predetermined audio may be modified (either dynamically, automatically, or via user input), an embodiment will have buffered audio contents that may be leveraged in a backward-looking analysis to identify VA commands, queries, etc. This reduces the need to re-state actionable items, e.g., commands, to the VA post-activation. Thus, a user is free to continue discussions, tasks, etc., without re-stating such commands, queries, etc.
