Optionally, preset reference audio characteristic value sequence calculates corresponding DTW distance for terminal by DTW algorithm。
In actual applications, if reference audio characteristic value sequence is set to include the sequence of N number of crest and trough, so, feature according to DTW algorithm, crest and the quantity of trough that no matter extraneous tone audio frequency characteristics value sequence and first the machine tone audio frequency characteristics value sequence include are how many, a DTW distance is calculated according to extraneous tone audio frequency characteristics value sequence and preset reference audio characteristic value sequence, calculate the 2nd DTW distance with according to first the machine tone audio frequency characteristics value sequence and reference audio characteristic value sequence, all include N number of crest and namely trough is all normalized to N。
Owing to a DTW distance and the 2nd DTW distance have identical element number, namely there is identical crest and trough quantity, therefore, it can compare a DTW distance with the 2nd DTW distance。Specifically, the similarity of a DTW distance and the 2nd DTW distance is calculated, it is possible to pass through range formulaCalculate。Wherein, XiIt it is a DTW distance；YiIt it is the 2nd DTW distance。XiAnd YiThe sequence vector that respectively N number of DTW distance is constituted。
It addition, the calculated DTW distance of terminal, it is the audio-frequency fingerprint of extraneous tone, the calculated 2nd DTW distance of terminal, is the audio-frequency fingerprint of first the machine tone。And audio-frequency fingerprint is the one group of unique identification calculated according to audio signal, and similar audio frequency should have similar audio-frequency fingerprint。Therefore, in audio identification field, usually by comparing two audio-frequency fingerprints corresponding to audio frequency to determine that whether the two audio frequency is similar。That is, terminal is by calculating the similarity of a DTW distance and the 2nd DTW distance, the similarity of extraneous tone audio frequency characteristics value sequence and first the machine tone audio frequency characteristics value sequence can be calculated, thus judging that whether extraneous tone is similar with first the machine tone。
In practical application, terminal calculates a DTW distance according to extraneous tone audio frequency characteristics value sequence and preset reference audio characteristic value sequence；The 2nd DTW distance is calculated, it is possible to determined that module processes by the audio-frequency fingerprint arranged in terminal according to first the machine tone audio frequency characteristics value sequence and reference audio characteristic value sequence。Terminal calculates the similarity of a DTW distance and the 2nd DTW distance and can be processed by the similarity calculation module arranged in terminal。

Intelligible, owing to second the machine tone through Audio Processing is different from first the machine tone, therefore, when receiving employing first the machine tone and carrying out the communication information reminded, play second the machine tone, to be different from the extraneous tone of other terminal。
Alternatively, with reference to shown in Fig. 4, after step 103, method also includes step 107, particularly as follows:
Step 107: after preset time period, adopts first the machine tone to carry out the communication information reminded if receiving, then communication information is reminded by playing first the machine tone。
Understandably, after preset time period, illustrate that distance terminal gets the extraneous tone similar to first the machine tone and pass by the long period, it is believed that terminal current place environment is absent from the extraneous tone similar to first the machine tone, therefore, when terminal receives and adopts first the machine tone to carry out the communication information reminded, it is possible to continue through broadcasting first the machine tone and communication information is reminded。
Alternatively, with reference to shown in Fig. 5, after step 102, method also includes step 105-step 106, particularly as follows:
Step 105: when similarity is more than predetermined threshold value, other the machine tone that at least one except first the machine tone is preset carry out Audio Processing and obtain the 3rd the machine tone；
Step 106: in preset time period, adopts other the machine tone to carry out the communication information reminded if receiving, then by broadcasting the 3rd the machine tone, communication information is reminded。
In reality, terminal often presets the tone of corresponding different communication message when dispatching from the factory。For example, manufacturer terminal A, preset incoming call tone is A1, preset note tone to be A2, preset notice tone be A3, preset alarm clock tone are A4。Terminal 1 and terminal 2 all have vendor A to produce, so when terminal 1 does not change the notice tone carried, it is that any one tone in A4 is similar to terminal 2 when terminal 1 A2 that recognizes in surrounding that to be A1, note tone to the incoming call tone of self be, notice tone are A3, alarm clock tone, so, terminal 1 also have with other tone of terminal 2 bigger be probably similar。Therefore, other the machine tone that at least one except first the machine tone is preset are carried out Audio Processing and obtain the 3rd the machine tone by terminal needs。
