Abstract: A method and an apparatus for recognizing a voice are provided. The method may include: inputting a target voice into a pre-trained voice recognition model to obtain an initial text output by at least one recognition network in the voice recognition model, the recognition network including a plurality of preset types of processing layers, and at least one type of processing layer of the recognition network being obtained by training based on a voice sample in a preset direction interval; and determining a voice recognition result of the target voice, based on the initial text.

Abstract: The present disclosure discloses a control method and a control apparatus for speech interaction. The detailed implementation solution of the control method for the speech interaction includes: collecting an audio signal; detecting a wake-up word in the audio signal to obtain a wake-up word result; and playing a prompt tone and/or executing a speech instruction in the audio signal based on the wake-up word result.

Abstract: The disclosure provides a method for processing a speech signal, an electronic device and a storage medium. The method includes: obtaining a speech signal to be processed and a reference speech signal; obtaining a frequency-domain speech signal to be processed and a reference frequency-domain speech signal by respectively preprocessing the speech signal to be processed and the reference speech signal; obtaining a frequency-domain speech signal ratio by inputting the frequency-domain speech signal to be processed and the reference frequency-domain speech signal into a complex neural network model; and obtaining a target frequency-domain speech signal based on the frequency-domain speech signal ratio and the frequency-domain speech signal to be processed, and obtaining a target speech signal by processing the target frequency-domain speech signal.
