The present disclosure provides a method for voice enhancement, including: obtaining a first signal and a second signal of a target voice, the first signal being a signal of the target voice collected based on a first position, and the second signal being a signal of the target voice collected based on a second position; determining a first coefficient by processing, based on a position of the target voice, the first position, and the second position, the first signal and the second signal; determining, based on the first signal and the second signal, a plurality of parameters related to a plurality of sound source directions; determining, based on the plurality of parameters and the position of the target voice, a second coefficient; and obtaining a voice-enhanced first output voice signal corresponding to the target voice by processing the first signal and/or the second signal.

Methods and systems for voice enhancement

A voice activity detection method and system and a voice enhancement method and system are provided. A voice presence probability of a target voice signal present in microphone signals may be determined by calculating a linear correlation between a signal subspace where the microphone signals are located and a target subspace where the target voice signal is located. The voice enhancement method and system may be used to calculate filter coefficients based on the voice presence probability, so as to perform voice enhancement on the microphone signals. The calculation accuracy of the voice presence probability is improved, and the voice enhancement effect is also improved.

Open acoustic device

The present disclosure provides an acoustic device including a microphone array, a processor, and at least one speaker. The microphone array may be configured to acquire an environmental noise. The processor may be configured to estimate a sound field at a target spatial position using the microphone array. The target spatial position may be closer to an ear canal of a user than each microphone in the microphone array. The processor may be configured to generate a noise reduction signal based on the environmental noise and the sound field estimation of the target spatial position. The at least one speaker may be configured to output a target signal based on the noise reduction signal. The target signal may be used to reduce the environmental noise. The microphone array may be arranged in a target area to minimize an interference signal from the at least one speaker to the microphone array.

Acoustic devices

A fishing reel is provided. The fishing reel includes one or more sensors that can obtain data of the fishing reel in a first movement. The fishing reel also includes a computing device. The computing device can estimate a casting posture of a user of the fishing reel from a plurality of casting postures, based on the data of the fishing reel and a model classifying the plurality of casting postures. The casting posture corresponds to the first movement. The computing device can control an operation of the fishing reel based on the casting posture of the user, and transmit data of the casting posture to a separate device.

Intelligent fishing reel

Embodiments of the present disclosure disclose an earphone including a fixing structure, a first microphone array, a processor, and a speaker. The fixing structure is configured to fix the earphone near a user's ear without blocking the user's ear canal and including a hook-shaped component and a body part. The first microphone array is located in the body part and is configured to pick up environmental noise. The processor is located in the hook-shaped component or the body part and is configured to estimate a sound field at a target spatial position using the first microphone array and generate a noise reduction signal based on the estimated sound field. The target spatial position is closer to the user's ear canal than any microphone in the first microphone array. The speaker is located in the body part and is configured to output a target signal according to the noise reduction signal.
