我已經(jīng)安裝了PocketSphinx演示程序，并且在Ubuntu和Eclipse下運(yùn)行良好，但是盡管嘗試了一下，但仍無(wú)法弄清楚如何添加多個(gè)單詞的識(shí)別。我只想讓代碼識(shí)別單個(gè)單詞，然后我就可以在代碼中識(shí)別它們switch()，例如“上”，“下”，“左”，“右”。我不想識(shí)別句子，只能識(shí)別單個(gè)單詞。任何幫助，將不勝感激。我發(fā)現(xiàn)其他用戶也有類似的問(wèn)題，但到目前為止，沒(méi)人知道答案。讓我感到困惑的一件事是，為什么我們根本需要使用“喚醒”常量？private static final String KWS_SEARCH = "wakeup";private static final String KEYPHRASE = "oh mighty computer";...recognizer.addKeyphraseSearch(KWS_SEARCH, KEYPHRASE);有wakeup什么關(guān)系嗎？我已經(jīng)取得了一些進(jìn)步（？）：使用，addGrammarSearch我可以使用.gram文件列出我的單詞，例如up,down,left,right,forwards,backwards，如果我只說(shuō)那些特定的單詞，這似乎很好用。但是，任何其他字詞都將導(dǎo)致系統(tǒng)將所陳述的內(nèi)容與“最近”字詞進(jìn)行匹配。理想情況下，如果.gram文件中沒(méi)有說(shuō)出的單詞，我不希望被識(shí)別...

您可以使用addKeywordSearch哪個(gè)用于歸檔密鑰短語(yǔ)。每行一個(gè)短語(yǔ)，例如//中的每個(gè)短語(yǔ)都有閾值
up /1.0/
down /1.0/
left /1.0/
right /1.0/
forwards /1e-1/
必須選擇閾值以避免錯(cuò)誤警報(bào)。

正在為PocketSphinx演示更新Antinous修訂，以使其能夠在Android Studio上運(yùn)行。這就是我到目前為止
