Description of Related Art
There is an increased demand for systems which react on user speech in-put in a graphical way in order to improve the input interfaces of electronic devices and the handling of electronic devices in general. In every speech input system recognition errors or ambiguities of the language lead to a multitude of possibilities what the user could have said and which input command is related to the received speech input.
In known speech input systems many solutions are known how to handle recognition errors and ambiguities of the language, wherein e.g. either the command which is deemed to be the most probable is executed, the system asks the user to repeat the command if the ambiguities are too large or the system presents the user a list of possibilities of commands associated with the speech input. Further, speech input systems are known which show a preview of the impact of the user command identified by the system.
The known methods for identifying the speech input have either the disadvantage that the wrong command might be executed, that the recognition errors occur a plurality of times if the command has to be repeated or the differences between the listed possibilities is low so that it is difficult for the user to distinguish the offered commands to be executed. Consequently, the known systems are either less reliable or complicated for the user.
The “background” description provided herein is for the purpose of generally presenting the context of the disclosure. Work of the presently named inventor(s), to the extent it is described in this background section, as well as aspects of the description which may not otherwise qualify as prior art at the time of filing, are neither expressly or impliedly admitted as prior art against the present invention.
It is an object to provide an electronic device for identifying commands from a user having a higher reliability and which is less complicated for the user. It is a further object to provide a method for identifying commands of a user having an improved reliability and which is less complicated for the user, as well as a corresponding computer program for implementing the method and a non-transitory computer-readable recording medium for implementing the method.
According to a further aspect there is provided an electronic device, comprising:
According to an aspect there is provided a method for identifying commands of a user, comprising:
According to still further aspects a computer program comprising program means for causing a computer to carry out the steps of the method disclosed herein, when said computer program is carried out on a computer, as well as a non-transitory computer-readable recording medium that stores therein a computer program product, which, when executed by a processor, causes the method disclosed herein to be performed are provided.
Preferred embodiments are defined in the dependent claims. It shall be understood that the claimed method, the claimed computer program and the claimed computer-readable recording medium have similar and/or identical preferred embodiments as the claimed device and as claimed in the dependent claims.
One aspect of the present disclosure is to identify the input signals received from an input interface and to determine a plurality of possible commands on the basis of the input signals. The actions, consequences, results or effects associated with the determined possible commands are provided to the user so that the user can easily distinguish the effects of the commands and easily choose which of the commands or actions shall be executed. Preferably, one of the possible commands is finally selected on the basis of a user input signal, which may be a manual or a speech input signal. Since the effects associated with the different possible commands are presented to the user, the reliability of the identification of the commands is increased and since the user also sees the impact of the command a rollback of the consequences due to executing wrong commands can be avoided. Further, since the consequences of the different possible commands are provided to the user the step of identifying the command can be skipped so that the method in general is less complicated for the user.
The different output information presented to the user are preferably displayed on a display unit so that the user can visually check the effect of the possible input command and the possible effects or results are displayed corresponding to a confidence parameter so that the actions corresponding to the most probable identified input commands can be highlighted and the use of the identification method is less complicated.
It is to be understood that both the foregoing general description of the invention and the following detailed description are exemplary, but are not restrictive, of the invention.
A more complete appreciation of the disclosure and many of the attendant advantages thereof will be readily obtained as the same becomes better understood by reference to the following detailed description when considered in connection with the accompanying drawings, wherein:
Referring now to the drawings, wherein like reference numerals designate identical or corresponding parts throughout the several views,
The user interface comprises a speech interface 12 for receiving speech commands of the user. The speech interface comprises a microphone for detecting the audio signal surrounding the user interface 10. The user interface 10 comprises a central processing unit 14, which is connected to the speech interface 12, wherein the audio signals received by the speech interface 12 are provided to the central processing unit 14 for speech detection. The central processing unit 14 detects the speech received from the speech interface 12 and determines a plurality of input commands which correspond to expressions identified from the speech received by the speech interface 12.
The central processing unit 14 determines effects, actions or results corresponding to the plurality of determined input commands and provides the effects or actions to output interfaces of the user interface 10 in general. One of the output interfaces is a display screen 16 which is provided for displaying information to the user. If the effects or actions corresponding to the input commands are related to visual actions, the central processing unit 14 displays the corresponding effect or action on the display screen 16 as described in the following. In the case that the effect or action is an audio signal, e.g. playing different music, the central processing unit 14 provides a corresponding signal to speakers 18 of the user interface 10 and provides the corresponding audio signals to the user.
On the basis of the effects or actions corresponding to the input commands determined from the speech input signal, the user can select one of the effects or actions by means of an input signal in general and the central processing unit 14 executes the corresponding effect or action selected by the user. The input signal may be provided to the central processing unit 14 by means of an input device 20 which can be formed as a keyboard or can be a speech signal received and determined by the speech interface 12.
By means of the user interface 10, the actions or effects corresponding to the plurality of input commands determined from the speech input signal received by the speech interface 12 can be easily provided to the user and the user can easily select the effect or action which was intended by the speech signal. Since the action and effect is provided to the user, the reliability of the interface is improved and the handling of the user interface is more comfortable.
Within the images or pictures of the effects or actions 22-28 showing a snapshot of the desktop or a program or application surface or window, the result of the input command may be highlighted in order to show the result of the input command explicitly. For example if the deletion of an icon on the desktop is the result of the command, the respective location of the removed icon is highlighted by e.g. a colored circle or if the result would be the deletion of an e-mail in an e-mail program, the removed e-mail may be highlighted in the list of e-mails by a respective colored frame or circle 32, 34 as shown as an example in
The user can select the so-displayed effects or actions 22-28 by a manual input signal via the input unit 20 or by a speech input command e.g. by spelling a number of the respectively displayed effect or action 22-28.
If the respective effect or action 22-28 is displayed, the user can select the effect or action 22-28 by means of a manual input via the input device or by a speech input signal received by the voice interface 12.
