Embodiment Construction

[0029] Various example embodiments will now be described more fully with reference to the accompanying drawings, in which some example embodiments are shown.

[0030] Refer below figure 1 with Image 6 The speech enhancement method and device according to the embodiments of the present invention are described.

[0031] figure 1 A flowchart showing a speech enhancement method according to an embodiment of the present invention.

[0032] In step S10, voice data to be enhanced is received.

[0033] As an example, the speech data to be enhanced may be disturbed speech data. For example, the voice data to be enhanced may be data mixed with noise and voice, but the present invention is not limited thereto.

[0034] For example, the interference encountered by actual speech can usually be divided into the following categories: (1) Periodic noise, such as electrical interference, interference caused by the rotating part of the engine, etc.; (2) Impulse noise, such as noise interf...

Abstract

The invention provides a speech enhancement method and device, and the voice enhancement method includes the steps: receiving to-be-enhanced speech data; separating at least one speech stream from theto-be-enhanced speech data based on a long-term and short-term memory neural network; recognizing a target speech stream corresponding to the predetermined speech from at least one speech stream based on a time delay neural network; enhancing the target speech stream; and outputting the enhanced target voice stream. The speech enhancement method and device separate the enhanced speech data by thelong-term and short-term memory neural network, and then recognizes the target speech stream from the separated result through the time delay neural network, and then only enhances the target speechstream, so that the target speech is clear, thereby achieving the effect of noise reduction and effectively improving the user experience.

Description

technical field [0001] The present invention generally relates to the communication field, and more specifically, relates to a voice enhancement method and device. Background technique [0002] Speech enhancement refers to the technology of extracting useful speech signals from the noise background to suppress and reduce noise interference when the speech signal is interfered or even submerged by various noises. Its essence is speech noise reduction. Speech enhancement involves a wide range of applications, including: voice calls, conference calls, scene recording, military eavesdropping, hearing aid equipment, and voice recognition equipment. [0003] At present, the following two methods are generally used for speech enhancement: (1) On the basis of the original sound, noise reduction is directly performed for different types of noise. For example, direct noise reduction for types of noise such as car horns, wind, sirens, etc. However, it is usually difficult to eliminat...
