Problems solved by technology

In addition, the voice of the traditional telephone channel only uses 8k sampling rate, which belongs to narrowband voice, and the sound quality is damaged and there is an upper limit
Obviously, if you continue to use the traditional encoding method to process broadband or ultra-wideband voice, you need to increase the bit rate and double the traffic consumption

Embodiment Construction

[0039] In order to enable those skilled in the art to better understand the solutions of the embodiments of the present invention, the embodiments of the present invention will be further described in detail below in conjunction with the drawings and implementations.

[0040] Aiming at the problem that the traditional encoding method needs to increase the code rate and consume a lot of traffic when processing broadband or ultra-wideband voice, the embodiment of the present invention provides a voice signal sending method and system, and a voice signal receiving method and system, which are applicable to various Coding of similar speech (such as ultra-wideband speech with 16KHz sampling rate, narrowband speech with 8KHz sampling rate, etc.), under the premise of ensuring the minimum loss of sound quality in speech recovery, it can realize signal transmission with extremely low bit rate.

[0041] Such as figure 1 As shown, it is a flow chart of the voice signal sending method of...

Abstract

The invention discloses a speech signal sending method and system. The sending method includes: determining the text content corresponding to the continuous speech signal to be sent; determining the speech synthesis parameter model of each synthesis unit according to the text content; splicing the text content of each synthesis unit The speech synthesis parameter model obtains the speech synthesis parameter model sequence; determines the sequence number string corresponding to the speech synthesis parameter model sequence; sends the sequence number string to the receiving end, so that the receiving end restores the continuous voice according to the sequence number string Signal. The invention also discloses a voice signal receiving method and system. Utilizing the present invention can realize the signal transmission of extremely low code flow rate under the premise of ensuring the minimum sound quality loss of voice restoration.

Description

technical field [0001] The present invention relates to the technical field of signal transmission, in particular to a voice signal sending method and system, and a voice signal receiving method and system. Background technique [0002] With the popularity of the Internet and the promotion of portable devices, various chat software based on handheld devices have emerged as the times require. The natural humanization of voice interaction cannot be surpassed by other interaction methods, especially in the application of hand-held small-screen devices that are not conducive to handwriting key input. In this regard, many products support the voice interaction function, which transmits the voice signal received by a certain terminal to the destination terminal. For example, the WeChat product launched by Tencent supports the voice message transmission function of VoiceMessage. However, the amount of voice signal data directly transmitted is often huge, which brings a relatively ...
