Android 调用谷歌原生语音识别

刺骨的言语ヽ痛彻心扉 2022-09-16 11:08 309阅读 0赞

前提：

1.安装谷歌语音搜索APP

2.需要越狱连接外网

废话不多说，直接上代码

public void onClick(View v) \{  
//开启语音识别功能  
Intent intent = new Intent(  
RecognizerIntent.ACTION\_RECOGNIZE\_SPEECH);  
//设置模式，这里设置成自由模式  
intent.putExtra(RecognizerIntent.EXTRA\_LANGUAGE\_MODEL,RecognizerIntent.LANGUAGE\_MODEL\_FREE\_FORM);  
//提示语音开始文字  
intent.putExtra(RecognizerIntent.EXTRA\_PROMPT,"Please start your voice");  
//开始进行语音识别，这里先检测手机(模拟器)是否支持语音识别并且捕获异常  
try \{  
startActivityForResult(intent, RESULT\_SPEECH);  
txtText.setText("");  
\} catch (ActivityNotFoundException a) \{  
Toast t = Toast.makeText(getApplicationContext(),  
"Opps! Your device doesn't support Speech to Text",  
Toast.LENGTH\_SHORT);  
t.show();  
\}  
\}  
\});

使用onActivityResult接收返回的结果

@Override  
protected void onActivityResult(int requestCode, int resultCode, Intent data) \{  
super.onActivityResult(requestCode, resultCode, data);  
switch (requestCode) \{  
case RESULT\_SPEECH: \{  
if (resultCode == RESULT\_OK && data != null) \{  
ArrayList<String> text = data  
.getStringArrayListExtra(RecognizerIntent.EXTRA\_RESULTS);  
//这里集合列表中第一个值为匹配度最高的值  
txtText.setText(text.get(0));  
\}  
break;  
\}  
\}  
\}
