Problems solved by technology

[0002] Because some people will forget to press the key lock and accidentally make a call and enter the voice mailbox or forget to press the disconnect button after the call, causing the call to continue, and the user must pay an unnecessary fee after receiving the bill costs, resulting in a certain amount of waste
[0003] In addition, the current VAD (Voice Activity Detection) technology is relatively mature, but the previous VAD technology was used in the recording function. It only records when someone is talking, and automatically stops recording when no one is talking. This technology has not been used in the function of the mobile phone to automatically hang up the phone

Embodiment Construction

[0012] The purpose of the present invention is to use the VAD technology to automatically hang up the call when the inactive sound frame lasts for more than a period of time during the call between the two parties. First, the theoretical basis of the present invention will be described below.

[0013] VAD technology: use speech characteristic parameters (energy, zero-crossing rate, sum of vocal tract cross-sectional area parameters, pitch cycle and spectrum distortion) to calculate the quantization value of the input sound frame, and use this quantization value to make the next step of active sound frame and non- The judgment of the active sound frame. Wherein the active sound frame refers to the dialogue voice (Active voice) in the conversation between the two parties during the call; and the inactive sound frame refers to the sound of pause or background noise (Inactive voice) in the conversation between the two parties during the call.

[0014] like figure 1 Shown is a fl...

Abstract

The invention discloses an automatic hanging-up method, which comprises the following steps of: a, setting a hanging-up critical time; b, in a call of a mobile phone, clearing a value N of a timer; c, acquiring remote voices and local voices; d, calculating a remote voice parameter quantitative value and a local voice parameter quantitative value respectively; e, judging whether the local voices and the remote voices are all inactive frames or not according to the obtained remote voice parameter quantitative value and the obtained local voice parameter quantitative value, entering a step f if the local voices and the remote voices are all inactive frames, otherwise returning to the step b; f, setting the value N of the timer to be N+1; and g, when the time N of the timer is more than the set critical time, controlling the automatic hanging-up of the mobile phone. The invention also provides an automatic hanging-up system. By the method and the system, automatic hanging-up can be realized so as to avoid unnecessary wastes.

Description

technical field [0001] The invention relates to a method and system for automatically hanging up a phone. Background technique [0002] Because some people will forget to press the key lock and accidentally make a call and enter the voice mailbox or forget to press the disconnect button after the call, causing the call to continue, and the user must pay an unnecessary fee after receiving the bill costs, resulting in a certain amount of waste. [0003] In addition, the current VAD (Voice Activity Detection) technology is relatively mature, but the previous VAD technology was used in the recording function. It only records when someone is talking, and automatically stops recording when no one is talking. This technology is not used in the function of the mobile phone to hang up the phone automatically. Contents of the invention [0004] In view of the above, it is necessary to provide a method for automatically hanging up the phone, which uses VAD technology to automatical...
