Android同时进行语音识别和录音

发布于 2024-12-01 11:27:02 字数 8793 浏览 1 评论 0原文

我的应用程序使用 AsyncTask 中的 MediaRecorder 类记录音频，并使用 Google API 将语音转换为文本 - 识别器意图 - 使用此问题中的代码： 如何在 Android 手机中使用语音识别而不出现烦人的对话框

我有还尝试在线程中录制音频，但这是更糟糕的解决方案。它会导致更多问题。我的问题是我的应用程序在模拟器上正常工作。但模拟器不支持语音识别，因为缺乏语音识别服务。在我的设备上，当我开始录制音频和语音识别时，我的应用程序崩溃了 - “意外停止”。但是，当我关闭 wifi 时，应用程序可以像在模拟器上一样正常工作。

在 AndroidManifest 中录制音频需要：

<uses-permission android:name="android.permission.RECORD_AUDIO" />

并且语音识别需要：

<uses-permission android:name="android.permission.RECORD_AUDIO" />
<uses-permission android:name="android.permission.INTERNET" />

我想这是单音频输入的问题吗？我该如何解决这个问题？ Google 语音识别器需要在主 UI 线程中工作，因此我无法在异步任务中执行此操作。所以我在异步任务中有录音。我不知道为什么这会引起问题。

我已将设备连接到 Eclipse 并使用 USB 调试。这是我在 LogCat 中的执行：

My application records audio using MediaRecorder class in AsyncTask and also use Google API transform speech to text - Recognizer Intent - using the code from this question : How can I use speech recognition without the annoying dialog in android phones

I have tried also to record audio in Thread, but this is worse solution. It causes more problems. My problem is that my application works properly on emulator. But emulator don't supports speech reocognition because of lack of voice recognition services. And on my device my application has crash when I starts recording audio and speech reognizing - "has stopped unexpectedly". However when I have wifi turned off, application works properly like on emulator.

Recording audio requires in AndroidManifest:

<uses-permission android:name="android.permission.RECORD_AUDIO" />

and speech recognition requiers:

<uses-permission android:name="android.permission.RECORD_AUDIO" />
<uses-permission android:name="android.permission.INTERNET" />

I suppose this is problem with single audio input? How can I resolve this problem?
Google Speech Recognizer requiers to work in main UI thread, so I can't for example do it in Async Task. So I have audio recording in Async Task. I don't have idea why this causes problems.

I have connected my device to Eclipse and I have used USB debugging. And this is execption I have in LogCat:

一袭水袖舞倾城 2024-12-08 11:27:02

我得到了一个运行良好的解决方案，可以进行语音识别和录音。这是我创建的一个简单 Android 项目的链接，用于展示该解决方案的工作原理。另外，我在项目中放置了一些打印屏幕来说明该应用程序。

我将尝试简要解释我使用的方法。我在该项目中结合了两个功能：Google Speech API 和 Flac 录音。

Google Speech API 通过 HTTP 连接调用。 Mike Pultz 提供有关 API 的更多详细信息：

“(...)新的 [Google] API 是一种全双工流 API。这意味着它实际上使用两个 HTTP 连接 - 一个 POST 请求将内容作为“实时”分块上传流，以及一个第二个 GET 请求来访问结果，这对于较长的音频样本或流音频更有意义。”

但是，此 API 需要接收 FLAC 声音文件才能正常工作。这让我们进入第二部分：Flac 录音

我通过从名为 AudioBoo 的开源应用程序中提取和改编一些代码和库，在该项目中实现了 Flac 录音。 AudioBoo 使用本机代码来录制和播放 flac 格式。

因此，可以录制 flac 声音，将其发送到 Google Speech API，获取文本，然后播放刚刚录制的声音。

我创建的项目具有使其发挥作用的基本原则，并且可以针对特定情况进行改进。为了使其在不同的场景中工作，需要获得 Google Speech API 密钥，该密钥是通过加入 Google Chromium-dev 小组获得的。我在该项目中留下了一把钥匙只是为了表明它正在工作，但我最终会删除它。如果有人需要更多相关信息，请告诉我，因为我无法在这篇文章中放置超过 2 个链接。

I got a solution that is working well to have speech recognizing and audio recording. Here is the link to a simple Android project I created to show the solution's working. Also, I put some print screens inside the project to illustrate the app.

I'm gonna try to explain briefly the approach I used. I combined two features in that project: Google Speech API and Flac recording.

Google Speech API is called through HTTP connections. Mike Pultz gives more details about the API:

"(...) the new [Google] API is a full-duplex streaming API. What this means, is that it actually uses two HTTP connections- one POST request to upload the content as a “live” chunked stream, and a second GET request to access the results, which makes much more sense for longer audio samples, or for streaming audio."

However, this API needs to receive a FLAC sound file to work properly. That makes us to go to the second part: Flac recording

I implemented Flac recording in that project through extracting and adapting some pieces of code and libraries from an open source app called AudioBoo. AudioBoo uses native code to record and play flac format.

Thus, it's possible to record a flac sound, send it to Google Speech API, get the text, and play the sound that was just recorded.

The project I created has the basic principles to make it work and can be improved for specific situations. In order to make it work in a different scenario, it's necessary to get a Google Speech API key, which is obtained by being part of Google Chromium-dev group. I left one key in that project just to show it's working, but I'll remove it eventually. If someone needs more information about it, let me know cause I'm not able to put more than 2 links in this post.

迟到的答案，但对于第一个例外，您必须在完成您想要的操作后销毁您的 SpeechRecognizer，例如（在 onStop() 或 onDestroy() 中或在您不再需要 SpeechRecognizer 之后直接销毁）：

    if (YourSpeechRecognizer != null)
    {
        YourSpeechRecognizer.stopListening();
        YourSpeechRecognizer.cancel();
        YourSpeechRecognizer.destroy();
    }

Late Answer, but for the first Exception, You have to destroy Your SpeechRecognizer after this what You want has done, for example (in onStop() or onDestroy() or directly after You don´t need the SpeechRecognizer anymore):

    if (YourSpeechRecognizer != null)
    {
        YourSpeechRecognizer.stopListening();
        YourSpeechRecognizer.cancel();
        YourSpeechRecognizer.destroy();
    }

在 CLOUD SPEECH API 的帮助下，我成功完成了这一任务。
您可以通过 Google Speech 找到它的演示。

API 可识别 80 多种语言和变体，以支持您的
全球用户群。您可以转录用户口述的文本
应用程序的麦克风，通过语音启用命令和控制，或者
转录音频文件以及许多其他用例。识别音频
在请求中上传，并与您的音频存储集成
Google Cloud Storage，使用与 Google 相同的技术
为自己的产品提供动力。

它在 Google Speech API 的帮助下使用音频缓冲区来转录数据。我在 AudioRecorder 的帮助下使用此缓冲区来存储音频录制。

因此，通过这个演示，我们可以与录音并行转录用户的语音。

在此，它启动和停止基于语音的语音识别。它还在 VoiceRecorder.java 与 EXTRA_SPEECH_INPUT_COMPLETE_SILENCE_LENGTH_MILLIS，共 RecognizerIntent，但由用户控制。

总而言之，您可以指定静音超时，并基于此它将在用户输出后停止并在用户开始说话时立即重新开始。

I have successfully accomplished this with the help of CLOUD SPEECH API.
You can find it's demo by google speech.

The API recognizes over 80 languages and variants, to support your
global user base. You can transcribe the text of users dictating to an
application’s microphone, enable command-and-control through voice, or
transcribe audio files, among many other use cases. Recognize audio
uploaded in the request, and integrate with your audio storage on
Google Cloud Storage, by using the same technology Google uses to
power its own products.

It uses audio buffer to transcribe data with help of Google Speech API. I have used this buffer to store Audio recording with help of AudioRecorder.

So with this demo we can transcribe user's speech parallely with Audio Recording.

In this, it starts and stops speech recognition based on voice. It also gives a facility of SPEECH_TIMEOUT_MILLIS in VoiceRecorder.java which is just same as EXTRA_SPEECH_INPUT_COMPLETE_SILENCE_LENGTH_MILLIS of RecognizerIntent, but user controlled.

So all in all, you can specify silence timeout and based on that it will stop after user output and start again as soon as user starts speaking.

最近关于“google-speech”等的项目'android-opus' (opuslib) 允许简单、并发的识别将音频录制到 android ext 中的 opus 文件。贮存。

查看 VoiceRecorder在语音项目中，只需要额外几行代码读取麦克风缓冲区后，缓冲区除了当前的语音观察器之外，还可以由 fileSink（PCM16 到 Opus 编解码器）使用。

请参阅 Google-speech-opus-recorder

Recent projects on 'google-speech' and on 'android-opus' (opuslib) allow simple, concurrent recognition along with audio record to an opus file in android ext. storage.

Looking at the VoiceRecorder in the speech project , with only a few extra lines of code after reading the microphone buffer, the buffer can also be consumed by a fileSink (PCM16 to Opus-codec) in addition to the current speech-observer.

see minimal merge of the 2 projects above in Google-speech-opus-recorder

我还没有测试过这个解决方案，但也许有可能。在 http://developer.android.com/reference/android/speech/ RecognitionService.Callback.html 有方法 void bufferReceived(byte[] buffer)。可能的解决方案是将接收到的缓冲区保存在 AudioRecord Android 类中。它具有类似read(byte[] audioData, int offsetInBytes, int sizeInBytes)的方法。那么也许可以通过这种方式连接这两个实用程序？配置 AudioRecord 以及录制后将结果转换为 mp3 或 wav 格式时可能会出现问题。

I haven't tested this solution yet but maybe there is a possibility. In http://developer.android.com/reference/android/speech/RecognitionService.Callback.html there is method void bufferReceived(byte[] buffer). The possible solution is to saving this recived buffer in AudioRecord Android class. It has method like read(byte[] audioData, int offsetInBytes, int sizeInBytes). So maybe it is possible to connect this two utilities in this way? Problems might have occurred with configuring AudioRecord and with converting the result to mp3 or wav format after recording.
