我向文本应用程序阿拉伯语发表了演讲。语音文本的结果将与数组中的现有文本进行比较。使用字符串算法 macthing Jaro-Winkler 距离我一直在计算所有文本输入的手册以及数组中的文本,结果是 1.0。但是当应用程序按照比较的结果运行时是不计算的。
此文本数组数据:
int [] soal={R.raw.alikhlas,R.raw.alfalaq,R.raw.alkafirun};
String [] jawaban={"لم يلدولم يولد","ومن شرغاسق اذاوقب","ولاانتم عبدون مااعبد"};
将数组和输入语音转换为文本
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
super.onActivityResult(requestCode, resultCode, data);
switch (requestCode) {
case REQ_CODE_SPEECH_INPUT: {
if (resultCode == RESULT_OK && null != data) {
ArrayList<String> result = data
.getStringArrayListExtra(RecognizerIntent.EXTRA_RESULTS);
String hasil = result.get(0);
JaroWinkler jw = new JaroWinkler();
String angka = String.valueOf(jw.similarity(hasil,jawaban[0]));
txtSpeechInput.setText(result.get(0) + "\n"+angka);
}
这个算法 Jaro Winkler 距离
