  • Publication number: 20240005917
    Abstract: Disclosed are a speech interaction method, computer readable storage medium, and electronic device, improving processing efficiency in multi-channel speech interaction scenarios with low resource consumption and processing delay. The method includes: obtaining at least one channel of audio signal; recognizing the at least one channel of audio signal using a preset speech recognition model, to obtain a first type of recognition result; determining stored recognition data from a buffer; generating a second type of recognition result based on the stored recognition data; processing the first and second type of results using the model, to obtain at least one statement recognition result corresponding to the at least one channel of audio signal; performing semantic parsing on the statement recognition result, to obtain at least one parsing result; and generating, based on the at least one parsing result, an instruction for controlling a speech interaction device to perform a corresponding function.

  • Publication number: 20240004606
    Abstract: Disclosed in the embodiments of the present disclosure are an audio playback method and apparatus, a computer readable storage medium, and an electronic device. The method includes: acquiring intention determination data collected for at least one user within a target space; determining that at least one user has a target vocal intention based on the intention determination data, and then determining feature information representing a current feature of the at least one user; and extracting and playing an audio corresponding to the feature information from a preset audio library. According to the embodiments of the present disclosure, it is achieved to automatically perform a determination on the target vocal intention of the user by the electronic device, without triggering an audio playing operation by the user, the steps of performing the audio playing operation by the user being omitted, and the convenience of the audio playing operation being improved.

  • Patent number: 11183179
    Abstract: Disclosed is a method and an apparatus for recognizing speech, and the method comprises: separating an input audio signal into at least two separated signals; generating a denoised signal at a current frame; performing a preliminary recognition on each interesting signal at the current frame; and performing a recognition decision according to a recognition score of each interesting signal at the current frame. The method and apparatus of the present disclosure deeply integrate an array signal processing and a speech recognition and use multiway recognitions such that a good recognition rate may be obtained even in a case of a low signal-to-noise ratio.

  • Publication number: 20100149190
    Abstract: An apparatus for providing an input order independent character input mechanism may include a processor. The processor may be configured to receive an input comprising an element corresponding to a portion of a character being entered by a user independent of an order for inputting the element based on the portion of the character corresponding to the element, wherein receiving an input comprises receiving at least one radical. The processor may additionally be configured to retrieve at least one candidate character for the character being entered based at least in part on the received element. The processor may also be configured to provide a selection of candidate characters including the at least one candidate character to the user. Associated methods and computer program products may also be provided.
