以下是关于Android语音到文本示例的完善且全面的答案:
Android语音到文本示例是一个应用程序,它可以将用户的语音输入转换为文本。这是一种非常有用的功能,可以帮助用户更轻松地与应用程序进行交互,而不需要手动输入文本。以下是一些关键点,可以帮助您实现这个功能:
以下是一个简单的示例代码,演示如何使用腾讯云语音识别API将语音转换为文本:
import com.tencentcloudapi.asr.v20190614.AsrClient;
import com.tencentcloudapi.asr.v20190614.models.SentenceRecognitionRequest;
import com.tencentcloudapi.asr.v20190614.models.SentenceRecognitionResponse;
import com.tencentcloudapi.common.Credential;
import com.tencentcloudapi.common.exception.TencentCloudSDKException;
public class VoiceToTextActivity extends AppCompatActivity {
private static final int REQUEST_RECORD_AUDIO_CODE = 1;
private Button recordButton;
private TextView resultTextView;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_voice_to_text);
recordButton = findViewById(R.id.record_button);
resultTextView = findViewById(R.id.result_text_view);
recordButton.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
if (ContextCompat.checkSelfPermission(VoiceToTextActivity.this, Manifest.permission.RECORD_AUDIO) != PackageManager.PERMISSION_GRANTED) {
ActivityCompat.requestPermissions(VoiceToTextActivity.this, new String[]{Manifest.permission.RECORD_AUDIO}, REQUEST_RECORD_AUDIO_CODE);
} else {
startRecording();
}
}
});
}
private void startRecording() {
// Start recording audio
// ...
// Convert audio to text
convertAudioToText(audioFilePath);
}
private void convertAudioToText(String audioFilePath) {
// Create credentials
Credential cred = new Credential("secretId", "secretKey");
// Create client
AsrClient client = new AsrClient(cred, "ap-shanghai");
// Create request
SentenceRecognitionRequest req = new SentenceRecognitionRequest();
req.setProjectId(0L);
req.setSubServiceType(2L);
req.setEngSerViceType("16k_zh");
req.setSourceType(0L);
req.setVoiceFormat("mp3");
req.setUsrAudioKey("test");
req.setData("data");
req.setDataLen(0L);
// Call API
try {
SentenceRecognitionResponse resp = client.SentenceRecognition(req);
String result = resp.getResult();
resultTextView.setText(result);
} catch (TencentCloudSDKException e) {
e.printStackTrace();
}
}
@Override
public void onRequestPermissionsResult(int requestCode, @NonNull String[] permissions, @NonNull int[] grantResults) {
if (requestCode == REQUEST_RECORD_AUDIO_CODE) {
if (grantResults.length > 0 && grantResults[0] == PackageManager.PERMISSION_GRANTED) {
startRecording();
} else {
Toast.makeText(this, "Permission denied", Toast.LENGTH_SHORT).show();
}
}
}
}
