我做了很多研究并尝试了离线袖珍狮身人面像，但它正在接受周围的声音，并对我的应用程序做出不同的反应。是否有任何适用于 kitkat 4.4 的 Google 离线应用程序。我从 2 周开始尝试它。感谢您的宝贵回答。
详细信息：当活动开始时，第一个文本必须在完成后阅读内容（文本到语音），阅读语音识别必须采取语音并按照命令例如：（下一个、上一个、前进、选项、1、2、3， 4等）。根据命令，它必须在 onresult 方法中识别并对其做出反应。
错误：我听到一些声音后出现错误
06-18 19:54:00.159: V/onBeginningOfSpeech(3360): onBeginningOfSpeech
06-18 19:54:01.024: V/onPartialResult(3360): option

06-18 19:54:01.111: V/onResult(3360): onResult
但是，如果我关闭互联网，它就无法离线工作。
在pocketsphinx中，它对正确的单词没有反应。如果我说“下一个”，它会靠近另一个人的语音内容附加“密钥”，这给我带来了很多问题。是否有任何解决方案或库可以离线使用。任何离线谷歌离线语音支持。

更新：
如果你使用addKeywordSearch
File digitsGrammar = new File(context.getFilesDir(), "digits.gram");
recognizer.addKeywordSearch(DIGITS_SEARCH, digitsGrammar);
然后在 digit.gram 中只写
option one /1e-1/
option two /1e-1/
option three /1e-1/
option four /1e-1/
back /1e-1/
previous /1e-1/
next /1e-1/
或者
如果您使用的是 addGrammarSearch
File digitsGrammar = new File(context.getFilesDir(), "digits.gram");
recognizer.addGrammarSearch(DIGITS_SEARCH, digitsGrammar);
然后在 digit.gram
#JSGF V1.0;
grammar digits;
<digit> = option one |
option two |
option three |
option four |
back |
previous |
next;
public <digits> = <digit>+;
