The yield value of set of frequency is not identical, after audio devices detect that the second audio mode is different from the first audio mode, selects
Second audio mode of user setting plays the audio data.And record the second audio mode, next time analysis for
When the corresponding spectrum analysis data of former first audio mode, the second audio mode, i.e. human voice patterns of usage record are played pair
The audio data answered.If audio devices detect that the first audio mode is identical as the second audio mode, i.e., user does not change first
Audio mode then records and uses the corresponding audio data of the first audio mode playback.
In addition, if operating terminal does not send the instruction for changing audio mode or sends the finger for the first audio mode that determines
It enables, then uses the first audio mode.For example, user is satisfied with the result of broadcast of the first audio mode, then without changing audio mould
The operation of formula, or sent by mobile phone and the confirmation of the first audio mode is instructed, audio devices then record and use this first
The corresponding audio data of audio mode playback.
