An ambient lighting system for automobiles configured to illuminate a passenger compartment, comprises: an optical system in turn comprising: a plurality of RGB LED light sources; a structural support on which the light sources are placed; and a contact surface on which a user can interact, and through which light rays can exit. The ambient lighting system also includes: a control unit configured to control the RGB LED light sources in order to present light animations; and a touch sensor configured to detect touch of the contact surface in a defined region, which is configured to define, along the optical system at least one soft key. The ambient lighting system further includes: a voice command recognition system electronically connected to the control unit and configured to recognize voice commands; and a projector configured to project an image, such as a symbol and/or logo, on the contact surface.

A method for operating a voice trigger is provided. In some implementations, the method is performed at an electronic device including one or more processors and memory storing instructions for execution by the one or more processors. The method includes receiving a sound input. The sound input may correspond to a spoken word or phrase, or a portion thereof. The method includes determining whether at least a portion of the sound input corresponds to a predetermined type of sound, such as a human voice. The method includes, upon a determination that at least a portion of the sound input corresponds to the predetermined type, determining whether the sound input includes predetermined content, such as a predetermined trigger word or phrase. The method also includes, upon a determination that the sound input includes the predetermined content, initiating a speech-based service, such as a voice-based digital assistant.

Disclosed herein are a text input apparatus for improving speech recognition performance and a method using the same. The text input method may include arranging all characters on an input screen including multiple key input areas in consideration of usage frequency of respective characters and usage association between the characters, setting input schemes for all the characters in consideration of positions of the multiple key input areas and positions of characters arranged in each key input area, and inputting characters through touch-based input corresponding to the input schemes.

An agent system includes a first memory and a first processor coupled to the first memory. The first processor analyzes contents of a verbal question, and carries out pre-processing that replaces vocabulary, which is used in the contents of the question, with homogenized vocabulary, and generates response information based on results of analysis. In a case in which there exists substitution vocabulary that has replaced original vocabulary in the pre-processing, the first processor changes the response information such that it can be recognized that the substitution vocabulary in the response information is synonymous with the original vocabulary, and outputs the response information.

This disclosure describes techniques for identifying users that are enrolled for use of a user-recognition system. To be identified using the user-recognition system, a user may first enroll in the system by stating an utterance at a first device having a first microphone. In response, the first microphone may generate first audio data. Later, when the user would like to be identified by the system, the user may state the utterance again, although this time to a second device having a second microphone. This second microphone may accordingly generate second audio data. Because the acoustic response of the first microphone may differ from the acoustic response of the second microphone, however, this disclosure describes techniques to apply a relative transfer function to one or both of the first or second audio data prior to comparing these data so as to increase the recognition accuracy of the system.

A microphone unit has a transducer, for generating an electrical audio signal from a received acoustic signal; a speech coder, for obtaining compressed speech data from the audio signal; and a digital output, for supplying digital signals representing said compressed speech data. The speech coder may be a lossy speech coder, and may contain a bank of filters with centre frequencies that are non-uniformly spaced, for example mel frequencies.

An input display device includes: a processor to execute a program; and a memory to store the program which, when executed by the processor, results in performance of steps including: receiving an input of a track by a receiving unit; generating a track image showing the track; acquiring a character string; and displaying the character string acquired in the acquiring to be superimposed on the track image. When the character string is acquired in the acquiring before the track image is generated, the displaying the character string is stood by.

In an approach to controlling voice command execution via boundary creation, one or more computer processors determine one or more devices included in an Internet of Things platform. One or more computer processors receive, from a user, an indication of a boundary around two or more devices of the one or more devices. One or more computer processors create a boundary around the two or more devices of the one or more devices. One or more computer processors receive a voice command from the user associated with the two or more devices of the one or more devices. One or more computer processors transmit the voice command to the two or more devices of the one or more devices within the boundary.
