A method and an apparatus for determining an echo, and a storage medium. The implementation solution includes: obtaining an echo estimation result by performing echo estimation on an original audio signal; obtaining an optimization processing result by performing optimization processing on the echo estimation result, the optimization processing includes at least one of amplitude dimension optimization processing, phase dimension optimization processing, or time domain dimension optimization processing; and determining an echo of the original audio signal using the optimization processing result.

Method and apparatus for determining echo, and storage medium

The disclosure provides a speech control method, a speech control apparatus, an electronic device, and a storage medium. The method includes: acquiring target audio data sent by a client, the target audio data including audio data collected by the client within a target duration before wake-up and audio data collected by the client after wake-up; performing speech recognition on the target audio data; and controlling the client based on an instruction recognized from a second audio segment of the target audio data in response to recognizing a wake-up word from a first audio segment at beginning of the target audio data; in which, the second audio segment is later than the first audio segment or has an overlapping portion with the first audio segment.

Speech control method, electronic device, and storage medium

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.

Control method and control apparatus for speech interaction, storage medium and system

Embodiments of the present disclosure disclose a method, apparatus and device for training a network, and a storage medium, relate to the field of artificial intelligence technology such as deep learning and speech analysis. A semantic prediction network comprises: an encoder network and at least one decoder network; and a particular solution is: acquiring a first speech feature of a target speech sample; the target speech sample being a synthesized speech sample or a real speech sample, the synthesized speech sample being attached with a sample syllable label and a semantic label comprising a value of the domain, and the real speech sample being attached with a sample syllable label; and jointly training an initial semantic prediction network and a syllable classification network using the first speech feature of the target speech sample, to obtain a trained semantic prediction network.

Control method and control apparatus for speech interaction

The present disclosure provides a method and an apparatus for waking up via a speech. The method includes: obtaining audio data currently collected by an electronic device through an audio-video interface on a hardware abstraction layer of the electronic device; performing noise reduction processing on the collected audio data to generate audio data to be detected; performing wake-up phrase detection on the audio data to be detected to determine whether the audio data to be detected includes a wake-up phrase; and performing wake-up processing on the electronic device in response to determining that the audio data to be detected comprises the wake-up phrase.
