我正在开发翻译应用程序，我需要说出用户翻译的内容。通过关注华为Text to Speech Doc，我得到了错误。

                        Log.d(TAG, "onEvent: Pause");
                        break;

                    // Pay attention to the following callback events when you focus on only synthesized audio data but do not use the internal player for playback:
                    case MLTtsConstants.EVENT_SYNTHESIS_START:
                        // Called when TTS starts.
                        Log.d(TAG, "onEvent: SynStart");
                        break;
                    case MLTtsConstants.EVENT_SYNTHESIS_END:
                        // Called when TTS ends.
                        Log.d(TAG, "onEvent: SynEnd");
                        break;
                    case MLTtsConstants.EVENT_SYNTHESIS_COMPLETE:
                        // TTS is complete. All synthesized audio streams are passed to the app.
                        boolean isInterruptedCheck = bundle.getBoolean(MLTtsConstants.EVENT_SYNTHESIS_INTERRUPTED);
                        Log.d(TAG, "onEvent: SynComplete");
                        break;
                    default:
                        break;
                
            
        );
       mlTtsEngine.speak("test", MLTtsEngine.QUEUE_APPEND);
    

目前，我只是为测试目的设置字符串“test”。我必须从模型中获取文本并将其设置为口语。我在有关扬声器错误的文档中看不到类似的内容。我已经搜索了 ErrorCode on Huawei。

public static final int ERR_ILLEGAL_PARAMETER

参数无效。

常数值：11301

LogCat：调试

LogCat：错误 任何帮助将非常感激。谢谢。

【参考方案1】：

我用英语设置了错误的人。所以改变这条线的代码

.setPerson(MLTtsConstants.TTS_SPEAKER_FEMALE_ZH)

与

.setPerson(MLTtsConstants.TTS_SPEAKER_MALE_EN)

工作得很好。
