虚拟设备支持语音识别吗？

Question

我正在尝试测试一个基于Google API实现语音识别的开源应用程序。 该应用程序似乎可以在真实电话上运行，但是在虚拟环境中，它会因网络错误而失败（SpeechRecognizer.ERROR_NETWORK，代码2）。 我看到了许多类似的问题，并且在一半的答案中，建议使用真实的电话。但是，这些回复来自2014年及之前。 现在在2020年左右，情况会发生变化吗？一个如何使用AVD测试语音识别应用程序？

我正在使用虚拟Nexus 6 API 26（Android 8.0，Google API），x86 CPU / ABI。

我已经将Google Play安装到模拟器中，并尝试了一些录音应用程序-它们工作正常。但是，即使授予了麦克风许可，另一个语音识别应用也无法正常工作（无法听到声音？）。
