synthesizeToFile失败：在Android中使用文字转语音时不绑定到TTS引擎， [英] synthesizeToFile failed: not bound to TTS engine , when using TextToSpeech in android

问题描述

我使用 Android的文字转语音API ，我想保存转换text2speech作为SD卡存储的文件，但我得到了错误：

  synthesizeToFile失败：不绑定到TTS引擎
 

我的code使用TTS是：

 公共无效的onActivityResult（INT申请code，INT结果code，意图意图）{
        如果（要求code == MY_DATA_CHECK_ code）{
            如果（结果code == TextToSpeech.Engine.CHECK_VOICE_DATA_PASS）{
                TTS =新的文字转语音（这一点，这一点）;                如果（getIntent（）！= NULL）{
                    如果（getIntent（）。getExtras（）！= NULL）{
                        。STRING D = getIntent（）getExtras（）的getString（数据）;                        串数据[] = d.split（ - ）;
                        BOOKNAME =数据[0];
                        loadPage（数据[0]，的Integer.parseInt（数据[1]））;
                    }
                }
                Log.d（TTS，数据加载）;            }
            其他{
                意图installTTSIntent =新的Intent（）;
                installTTSIntent.setAction（TextToSpeech.Engine.ACTION_INSTALL_TTS_DATA）;
                startActivity（installTTSIntent）;
            }
        }
    }
 

，其中里面的 loadPage（）函数的调用如下 synthesizeToFile 功能：

 字符串tempDestFile = appTmpPath.getAbsolutePath（）+/+文件名;
tts.synthesizeToFile（speakTextTxt，myHashRender，tempDestFile）;
 

解决方案

您必须等到的OnInit 调用之前，你可以叫讲话，synthesizeToFile 等...放在的OnInit 你的 loadPage 方法检查成功后有

I am using Android TextToSpeech API, I want to save the convert text2speech as a file on the SD-card memory, but I got the error:

 synthesizeToFile failed: not bound to TTS engine

My code to use TTS is :

public void onActivityResult(int requestCode, int resultCode, Intent intent) {


        if (requestCode == MY_DATA_CHECK_CODE) {
            if (resultCode == TextToSpeech.Engine.CHECK_VOICE_DATA_PASS) {
                tts = new TextToSpeech(this, this);

                if(getIntent() != null){
                    if(getIntent().getExtras()!=null){
                        String d = getIntent().getExtras().getString("data");

                        String data[] = d.split("-");
                        bookName = data[0];
                        loadPage(data[0], Integer.parseInt(data[1]));
                    }
                }
                Log.d("TTS","Data is loaded");

            }
            else {
                Intent installTTSIntent = new Intent();
                installTTSIntent.setAction(TextToSpeech.Engine.ACTION_INSTALL_TTS_DATA);
                startActivity(installTTSIntent);
            }
        }
    }

where inside the loadPage() function a call the synthesizeToFile function as below :

String tempDestFile = appTmpPath.getAbsolutePath() +"/"+ fileName;
tts.synthesizeToFile(speakTextTxt, myHashRender, tempDestFile);

解决方案

You have to wait until after onInit is called before you can call speak, synthesizeToFile etc... put your loadPage method in onInit after checking for success there.
