Step S101, browser is set up for obtain N the link that needs the voice document of reporting from server; N is positive integer.
Concrete, starting after navigation, browser is set up N different link, and the link of foundation is for obtaining M the voice document that next needs report from server.
In this preferred embodiment, the method that browser establishes the link is:
First, take HTML5 navigation as example, browser reads successively M voice document in the address of server from default configuration file, and described configuration file comprises more than one that voice document is in the address of server, M is positive integer, and the concrete numerical value of M can be configured according to demand; These voice documents refer to the voice document that starts next to need report from current location.
Then, browser using voice document in the address of server the property value as the source attribute (as SRC attribute) of the audio tag (as audio label) of self, the source attribute assignment of the audio tag that is browser with described voice document in the address of server, obtains thereby realize setting up from server the link that needs the voice document of reporting; Wherein, an audio tag is just equivalent to a link, in each audio tag (as SRC attribute), only configure an address, this voice document comprises URL(Uniform Resource Locator in the address of server, URL(uniform resource locator)) and the keyword of voice document, the play content of voice document can be summarized in the keyword of voice document, as title and the suggestion content etc. on the turning to of car, Distance Remaining, next road; The number N of audio tag is positive integer, and concrete numerical value can be configured according to demand.For example,, just like subaudio frequency label: <audio id=" media " src=" http://server.com/audio UTF-8 & text=1 kilometer is kept to the right " >.Like this, just can in audio tag, configure the voice document that need to obtain in the address of server, browser just can, according to the different address of configuration from the different voice document of server request, obtain voice document to realize from server in advance; If browser according to configuration M voice document after the complete corresponding voice document of address acquisition of server, also need to continue to read in configuration file lower M voice document in the address of server, then by address configuration in audio tag, continue to obtain voice document from server according to the address in audio tag, until navigation finishes.
