At the critical time, the mobile phone is controlled to automatically hang up the call, avoiding certain waste. [Embodiment] [0009] The object of the present invention is to use the VAD technology to automatically hang up a call when the inactive voice frame of the two parties continues for more than a period of time. The theoretical basis of the present invention will first be described below. [0010] VAD technology: using the speech characteristic parameters (energy, zero-crossing rate, channel cross-sectional area parameter, and pitch period and spectral distortion) to calculate the quantized value of the input sound box, and use the quantized value to make the next activity sound. The judgment of the box and the inactive sound box. The active sound box refers to the active voice in the conversation between the two parties during the call; and the inactive voice frame refers to the pause (inactive voice) in the conversation between the two parties during the conversation. [0011] As shown in FIG. 1, it is a method flow chart for determining whether it is an active sound box or an inactive sound box. First, the speech characteristic parameters P1, P2, . . . , Pn of the input signal are calculated, and secondly, by comparing the corresponding upper and lower limit values, the values f 1, f2, . . . fn of the corresponding output result are obtained. For example, for the speech characteristic parameter P1., the corresponding upper and lower limit values are THlu and ΤΗ, respectively. If P1 is greater than THl/^, the signal is determined to be an active sound box, and the obtained output result is Π The value is 1; if P1 is smaller than TH1/Temple, the signal is judged to be an inactive sound box, and the obtained output result fl is -1; if P1 is greater than TH and less than ^, the signal is still determined as For an inactive sound box, the resulting output result fl has a value of zero. The values f, ..., fn of the respective output results are respectively multiplied by their corresponding weighting values α 1, α 2 ... 098144352 Form number Α 0101 Page 6 / Total 17 pages 0982075816-0 201125347 «η, then summation, then Obtaining ^, which is the Fr=(«Ufl+aW2...an*fn) of the quantized value of the speech parameter; judging whether the obtained 疋No J; the maximum and final threshold value Fa, if less than, then judging It is an inactive sound box; if it is not smaller than Fth, it is turned off as the active sound box. [0012] [0015] [0015] FIG. 2 is an architecture diagram of a preferred embodiment of the present invention having a handset that automatically hangs up the telephone. The automatic hang-up telephone system operates in On the phone 1. The automatic hang up telephone system 2 includes a setting module 2, a timer 202, an obtaining module 204, a computing module 2〇6, a determining module 208, and a processing module 21 (referred to as the invention) The module refers to a computer program segment that performs a special function, and is more suitable for describing the execution process of the teaching body in the computer than the program. Therefore, the following software modules are described in the present invention. 200, configured to set a critical time T for hanging up the phone. The critical time T of the hanging call is a threshold for determining whether the mobile phone 1 automatically hangs up the phone. For example, the critical time for hanging up the phone may be set to 5 seconds, or 10 seconds. The setting module 200 is further configured to respectively set a final threshold value of the local sound and the far-end sound. The final n-limit value is used to determine whether the local sound and the far-end sound are inactive sounds. The threshold of the frame is used to start timing when both the local sound and the far-end sound are inactive. The time of the timing is N'N initial value is 〇. [0016] The acquisition module 204 is used. For getting the catching sound and the local sound.

When the obtained far-end speech parameter quantized value and the local S-sound parameter quantized value are both smaller than their corresponding final thresholds, the determining module 208 turns off both the local and the far-end sounds. The inactive sound box, on the other hand, determines that the local sound and the far end sound are not both inactive sound boxes. The determining module 208 is further configured to determine the timing when the local sound and the far end sound are both inactive sound boxes. Whether the timing time N of the device is greater than the critical time τ of the set hanging telephone, that is, whether the duration N when the local sound and the far-end sound are both inactive sound boxes is greater than the set hanging telephone The critical time T.
