我目前正在做一些關於Webkit語音識別的RnD,我想創建一個特定於應用程序的語法文件。 根據W3C定義,我寫了下面的代碼。但它似乎並沒有顯示出對這些詞的認可有了改進的結果。你能否提供一些幫助。?Web Speech API語法是否向開發人員公開?
var recognition = new webkitSpeechRecognition(); recognition.grammars.addFromUri(「voice/api_grammar/weight.grxml」);
語法文件是一個簡單的文件,看起來像下面這樣。
<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE grammar PUBLIC "-//W3C//DTD GRAMMAR 1.0//EN"
"http://www.w3.org/TR/speech-grammar/grammar.dtd">

<item repeat="0-3">
<ruleref uri="#alternatives"/>
</item>
</rule>
<rule id="sequence">
<example>

</example>
<example>

</example>
<example> <!-- this example is actually wrong but that is legal -->
warm sunny cloudy "Yorktown Heights" New York "United States"
</example>
<ruleref uri="#repeat"/> <ruleref uri="#ruleref"/>
<ruleref uri="#Token"/> <ruleref uri="#TOKEN"/>
</rule>
</grammar>
任何人都可以提供一些關於上述q的支持嗎?如果需要更多的描述,它當然可以完成。謝謝。 –
