Definitions
- the present invention relates to a voice control for a cooking stove.
- the invention relates to voice control of a cooker with multiple cooking zones.
- a cooking stove can be controlled based on an acoustic voice command.
- a voice recognition service can be used for this purpose, such as that known from Google, Amazon or Microsoft.
- the voice service can be accessed from a device that is independent of the cooktop, or it can be integrated into the cooktop. For example, a user can pronounce the voice command near the stove and the service can decode the voice information contained therein. Based on the results, the cooker can be controlled.
- a typical cooking range includes four cooking zones, several of which may be in use during the preparation of a meal.
- the voice command must contain an identification of the cooking zone.
- a user may find it counterintuitive to refer to a cooking zone by a predetermined designation such as 1, 2, 3, and 4. Referencing using a location such as "front left panel” can be perceived as cumbersome and time-consuming.
- a method for voice control of a cooker comprises the steps of detecting a voice command in the area of the cooker, the voice command relating to cookware standing on the cooker; determining the cookware; and driving the cooker to heat the cookware according to the voice command.
- a user can use a voice command that specifies the cookware to be heated in natural language.
- the voice command may not refer to the stove itself, but to its use to heat the cookware.
- a numerical indication or an indication of the location of the cooking utensil with respect to the cooker is preferably not required.
- the user can operate the stove more intuitively.
- An adjustment of the heating of the cookware crockery can be done easily and quickly.
- the risk of inadvertently controlling the heating of another cookware can be reduced.
- the cooking process can be made safer and the user can be less distracted by operating the cooker.
- the cooker preferably includes a household appliance that is set up in particular for use as a kitchen appliance in a household kitchen.
- the cooker is further preferably set up for the individual heating of several cookware. It is preferred that the cooker comprises different cooking zones.
- the cooking zones can be of different sizes and/or powerful and, in some embodiments, are permanently positioned on a stove surface. Each cooking zone can be set up to heat a piece of cookware placed on it.
- a cooking zone assigned to the cooking utensil can be determined, and the cooking zone determined can be controlled in order to heat the cooking utensil. If the user verbally references a specific pot, for example, and it is known which cooking zone this pot is assigned to, the assigned cooking zone can be controlled in a corresponding manner.
- the voice command also includes an indication of heating to be performed.
- This cue can be an absolute energy intake or relate to warming and be expressed on a scale from 0.5 to 3 or from 1 to 9, for example.
- a change in heating can also be specified in the voice command, for example if the heating is to be increased or decreased by a specified number of levels.
- the heating of cookware can also be switched off using a voice command.
- Another voice command can be provided for switching off the entire cooker with all the cooking zones.
- a cooking zone may be predetermined or dynamically formed by the cooktop design. For example, multiple cooking zones can be configured to behave like a common, larger cooking zone.
- the cooktop may also include a plurality of cooking zones that are dynamically grouped to appropriately heat cookware placed on the cooktop. If the cookware is moved on a surface of the cooker, the cooking zone can follow it.
- the voice command characterizes the cookware.
- the voice command may refer to a frying pan, casserole, small saucepan, large saucepan, or copper kettle.
- a property of the cookware, by means of which the cookware can be identified, can be derived from the reference of the voice command to the cookware.
- the property can relate, for example, to a size, in particular a diameter or a height, a design, a material, a color or a purpose.
- the cooking utensil and a cooking zone can be assigned manually, preferably before or at the beginning of a cooking process, or it can be determined automatically.
- the cooker comprises an induction cooker and the cookware is determined based on an inductive property.
- An electromagnetic alternating field can be generated and the influence of the cookware on the alternating field can be determined.
- the inductive property can indicate, for example, a size or a material of the cooking utensil.
- the cooking utensil can be unambiguously determined on the basis of its inductive properties, with this determination being able to be assigned to a linguistic designation in advance or created by the user.
- the cooking utensil can be recognized optically. If the voice command includes an optically recognizable property of the cookware, the cookware can be determined on the basis of this property.
- a cookware can be identified by its usual kitchen-technical designation. For example, a pot, a steam cooker, a simmering pot, a pan, a casserole or a wok can be visually distinguished from one another and recognized. Cookware can also be differentiated based on optical qualities such as color or size, which can be specified in the voice command.
- the voice command characterizes the content of the cookware, so that the cookware can be determined based on its content.
- the user can express that the soup should be heated more or the pudding should only be kept warm carefully.
- An association between the content and the cooking utensil or between the content and a cooking zone can be carried out manually, for example, preferably at the start of a cooking process. Automatic determination is also possible.
- the two variants can also be executed in combination with one another if the voice command includes both an indication of the cookware and its contents.
- the contents of the cooking utensil are optically scanned and the cooking utensil is identified on the basis of its contents.
- a cooking zone can also be inferred directly from the contents of a cooking utensil, which can be controlled to change the heating of the contents.
- the content can be described verbally using visually recognizable qualities, for example a color, a function or a consistency can be specified. Another distinction can be made based on a set of content.
- the content is expressed verbally based on the product to be achieved by the cooking process.
- the voice command can refer to a roast, even though a piece of meat in a cookware must first be cooked to be properly labeled as such.
- a designation and possible synonyms must be known.
- possible optical qualities can be assigned to the designation.
- the food can be identified using machine learning methods. The optical impression of the food can be analyzed holistically.
- a heuristic is applied to resolve imprecise or ambiguous phrasing in the voice command as correctly as possible.
- the heuristics can take place as part of the speech recognition or as part of the analysis of the content. If the voice command refers to a soup, for example, but the cookware available on the cooker does not contain any soup, you can select the cookware whose contents come closest to the soup, for example dumpling or pasta water. Such a replacement can only be carried out if the described content and the present content have a predetermined minimum similarity.
- a control device for a cooking range comprises means for detecting a voice command in the region of the cooking range; a device for heating a cookware standing on the cooker; and a processing device.
- the processing device is set up to determine a piece of cooking utensil on the cooker, to which the voice command relates; and control heating of the particular cookware.
- a method described herein can be carried out partially or entirely by means of the control device.
- the processing device can comprise a programmable microcomputer or microcontroller and the method can be present in the form of a computer program product with program code means that can be executed thereon.
- the computer program product can also be stored on a permanently installed or removable computer-readable data medium. Additional features or advantages of the method can be transferred to the device or vice versa.
- the control device can also have a sensor, such as a camera, an infrared sensor or an ultrasonic sensor, for scanning an object standing on the stove include, wherein the processing device is set up to recognize the object.
- a sensor such as a camera, an infrared sensor or an ultrasonic sensor
- control device can have an interface for connecting to the service.
- the service can be implemented in particular as a server or offer, for example in a cloud.
- an external service can be used to analyze a locally recorded voice command and convert it into another form. This other form can in particular include the spoken text of the voice command in written form.
- a cooking range includes a control device as described herein.
- FIG. 1 shows a system with a cooker with a control device
- Figure 2 is a flow chart of a method for controlling a cooking range.
- FIG. 1 shows a system 100 with a cooker 105 and a control device 110.
- the cooker 105 is set up to heat cookware 115 in a controlled manner.
- a content 120 which usually comprises a meal or an intermediate product for preparing a meal.
- the cooking utensil 115 can be assigned a cooking zone 125 which is set up to cause the cooking utensil 115 to heat up.
- the cooking zone 125 can comprise, for example, an induction coil, an infrared lamp, a heating resistor or a similar device.
- a cooking zone 125 can be designed to be permanently predefined or configurable. For example, several adjacent cooking zones 125 can be connected to form one cooking zone 125.
- a cooking zone 125 can be assigned to each cooking utensil 115 for this purpose.
- the control device 110 includes a processing device 130, which is set up to control the cooker 105 in general or the at least one cooking zone 125 directly, a microphone 135 for detecting a voice command in the area of the cooker 105, and preferably a sensor 140 for scanning a cookware 115 or its content 120.
- the sensor 140 preferably works without contact and more preferably optically.
- it may include a camera that may be mounted in a position vertically above the cookware 115 .
- the camera 140 can be mounted in the area of an extractor hood that is mounted above the stove 105 .
- the camera 140 may individually or repeatedly provide images of the cooktop 105, cookware 115 placed thereon, and/or content 120 therein.
- the processing device 130 can be set up to track a change in a cooking utensil 115, for example if a pot lid has been put on or taken off in the meantime, or if a content 120 is filled in or removed.
- a change in the position of a cookware 115 on the cooker 105 or a change in an association between the cookware 115 and the cooking zone 125 can also be determined on the basis of the scanning by the processing device 130 .
- a voice command captured by the microphone 135 can be brought into a form that can be processed further by machine by recognizing the voice command. For this purpose, spoken words of the voice command can each be converted into their written representation. Speech recognition can be performed locally by the processing device 130 or by a remote service.
- the controller 110 includes an interface 145 for connection to a network 150 to reach a remote location 155 .
- the remote location 155 can be implemented, for example, as a server or service in a cloud.
- the network 150 can in particular include a mobile radio network or the Internet. Other networks are also possible. It is proposed that the control device 110 detects and evaluates a voice command spoken in the area of the stove 105 .
- the voice command relates to a cooking utensil 115 standing on the cooker 105 .
- the control device 110 should identify the cooking utensil 115 referenced in the voice command or a cooking zone 125 assigned to it and preferably control it according to another content of the voice command in order to bring about a corresponding heating of the cooking utensil 115.
- the assignment of a term used in the voice command to a piece of cooking utensil 115 or a cooking zone 125 can take place with respect to a scanning of the cooker 105 and in particular the cooking utensil 115 or its contents 120 located thereon.
- a voice command in the area of the stove 105 is detected.
- a linguistic content of the voice command can be determined.
- a local analysis can be carried out or an external service, for example on the part of the remote location 155, can be used.
- the result of the voice recognition is a representation of the voice command that can be further processed by a machine, especially in the form of a transcription. If the voice command can be unequivocally recognized, the method 200 can proceed to the execution of a step 250, as described in more detail below.
- the voice command relates to a cooking utensil 115 on the stove 105 .
- An example could be “pan”.
- a characteristic can be determined which is associated with the term used in the voice command.
- a shape or a size of a pan can be derived from the spoken information.
- a cooking utensil 115 on the cooker 105 can be determined, which meets the previously determined characteristic.
- further information can be found from the voice command can be used, for example when a size, shape, appearance or color of the cooking utensil 115 is specified.
- a fuzzy search may be used in determining the cookware 115 based on the voice command.
- a heuristic can be used to resolve an ambiguous or contradictory statement. The resolution may be done using external sources, for example an external service that provides a thesaurus to map a characteristic of an existing cookware 115 to a characteristic of a cookware 115 referenced in the voice command.
- the process of elimination may be used to identify the cookware 115 . If, for example, a Reine is referred to, while only pans and a wok are arranged on the cooker 105, the wok can be determined to be sufficiently similar to the Reine.
- a query can be sent to a user of the cooking stove 105 .
- the inquiry can be made in such a way that the user can recognize which existing cooking vessels 115 are at risk of being mixed up. If, for example, there are two differently sized pans and a pot on the cooker 105, and the user only refers to one pan in his voice command, the query can be related to which of the pans is meant.
- a cooking zone 125 assigned to the cooking utensil 115 can be determined. This assignment can be static or dynamic.
- step 210 after step 210 has been carried out, it can be determined in a step 235 that the voice command relates to the contents 120 of a cookware 115 on the cooker 105 .
- a characteristic of the referential content 120 can be determined. This step can be analogous to step 220 and the characteristic can be a type, a color or a surface texture of the content 120, for example. ok
- a content 120 of a piece of cooking utensil 115 on the stove 105 is determined, which has a characteristic corresponding to the voice command. For example, a cooking utensil with a temperature typical of a content, or a cooking utensil with a content having a typical color can be determined.
- the cooking utensil 115 can be determined on the basis of the content 120, and the assigned cooking zone 125 can be determined on this basis in step 230.
- the assigned cooking zone 125 can also be determined directly on the basis of the determined content 120.
- heating of the cooking utensil 115 or its content 120 to be controlled can be determined.
- the information can be provided, for example, in the form of an amount of energy, a temperature to be set, or with reference to a predetermined scale.
- a relative indication may be supported to heat the cookware 115 more or less.
- the cooking zone 125 can be controlled to heat the cooking utensil 115 appropriately. It is preferred that feedback is given to the user for this purpose.
- the feedback may carry a direct reference to the cooking zone 125 , for example in the form of a numeric indication visually indicated on the cooking range 105 .
- indirect referencing can also be used, preferably the same indirect referencing that was used in the voice command. The user can only confirm the feedback before the stove 105 is controlled.
