With reference to figure 3, Fig. 3 is the schematic flow sheet of play parameter Automatic adjustment method second embodiment of the present invention.
Based on above-mentioned first embodiment, the play parameter Automatic adjustment method that the present embodiment proposes is after step S30, alsoIncluding：
S50：When not finding target play parameter corresponding with the current speech feature, issue the user with parameter and setPut prompt message；
It is understood that phonetic feature corresponding to the user of voice signal is not each sent in intelligent sound boxThere are the play parameter being associated, such as the first user for using intelligent sound box, it is pre- not get user before intelligent sound boxIf play parameter, can not naturally also complete the play parameter of user preset being associated with the current speech feature gotThis operation.
Now, be improve user experience, intelligent sound box can be sent to the user for being not provided with play parameter prompt message withUser is prompted to carry out parameter setting, its specific prompting mode can also pass through the man-machine of intelligent sound box by voice broadcastInteractive panel display corresponds to word to remind user to carry out parameter setting, and the present embodiment is not any limitation as to this.
In the specific implementation, when intelligent sound box does not find target play parameter corresponding with the current speech featureWhen, by default prompting mode, such as voice broadcast user can be reminded to play out the setting of parameter.
Step S60：The parameter setting instruction of user's input is received, default broadcasting ginseng is extracted from the parameter setting instructionNumber；
It is understood that user is after the parameter setting prompt message that intelligent sound box is sent is received, still can basisSelf-demand chooses whether to carry out parameter setting, when intelligent sound box does not receive the parameter setting of user's input in preset timeDuring instruction, then give tacit consent to active user and refuse to carry out parameter setting, now play parameter can be arranged to initial play by intelligent sound boxParameter, the initial play parameter can be the play parameter set when intelligent sound box equipment is dispatched from the factory, and the preset time can be withSet according to actual conditions, such as 30 seconds, 40 seconds or 60 seconds etc., the present embodiment is not any limitation as to this.
When intelligent sound box receives the parameter setting instruction of user's input in preset time, the parameter setting is referred toOrder is parsed, and obtains the default play parameter included in the parameter setting instruction.
Not have to regulation play parameter manually, institute when the user of first setting play parameter is reused the intelligent sound boxStating method also includes：The default play parameter and the current speech feature are associated, and to described pre- after associationIf play parameter and the current speech feature are stored.
In the specific implementation, intelligent sound box is opened or using audio amplifier for first, and the user of play parameter setting is carried out,Phonetic feature corresponding to the active user that will can be extracted creates user account, so for active user automatically as log-on messageThe play parameter of user preset is associated with the phonetic feature extracted afterwards, by the default play parameter after association and instituteCurrent speech feature is stated to be bound and preserved with the user account or account ID newly created.
To realize quick lookup to play parameter, in the phonetic feature to the play parameter of user preset with corresponding extraction, can be by establishing mapping table or database, by the default play parameter after association and described current after being associatedPhonetic feature is stored into the mapping table or database.
It should be noted that the mapping relations, it is mutually " right either between classification and classification between two elements to refer toShould " relation, you can with by pre-establishing this mapping relations, by the one of which element in the mapping relations orClassification, precisely rapidly find corresponding element or classification.The present embodiment is by establishing mapping table, after associationThe default play parameter and the current speech characteristic storage into the mapping table, so as to make intelligent sound boxWhen extracting phonetic feature, corresponding play parameter is rapidly searched according to the mapping table.
Step S70：Setting is played out according to the default play parameter.
