使用

使用和語音識別完全一致

初始化靈云的語音能力和語法識別

// 靈云語音工具類 mInitTts = new HciUtil(this); // 初始化靈云語音 boolean isInitHci = mInitTts.initHci(); if (isInitHci) { // 初始化成功……// 語音識別mAsrUtil = new AsrUtil(this); }

語法識別

/*** 語音識別（語音轉文字）** @param view view*/ public void asr(View view) {mAsrUtil.start(new AsrUtil.OnAsrRecogListener() {@Overridepublic void onAsrRecogResult(AsrRecogResult asrRecogResult) {StringBuilder stringBuffer = new StringBuilder();ArrayList<AsrRecogItem> asrRecogItemArrayList = asrRecogResult.getRecogItemList();for (AsrRecogItem asrRecogItem : asrRecogItemArrayList) {String result = asrRecogItem.getRecogResult();Log.i(TAG, "onAsrRecogResult: " + result);stringBuffer.append(result).append("\n");}showDialog("識別結果", stringBuffer.toString());}@Overridepublic void onError(int errorCode) {Log.i(TAG, "onError: " + errorCode);}@Overridepublic void onVolume(int volume) {Log.i(TAG, "onVolume: " + volume);}}); }

離線語音識別

在在線語法識別的基礎上，離線的語法識別只需要將CapKey替換，并且添加離線資源即可

離線資源的下載

下載完解壓離線資源

將里面所有的文件重命名，前面加lib，后面加.so，然后導入工程

修改CapKey為asr.local.grammar.v4

注意，靈云的離線語音功能第一次使用需要聯網激活，激活以后才可以使用離線功能。
