WearOS设备（三星Galaxy4/5、Pixel）集成Google Speech Listener报错求助

我们开发了一款适配所有WearOS智能手表的应用，该应用在Ticwatch上运行完全正常。但在搭载相同版本WearOS的三星Galaxy 4、5以及Pixel智能手表上，集成Google Speech Listener时遇到问题，出现报错：E/SpeechRecognizer: no selected voice recognition service（设备已安装所有最新版本）。

为排查问题，我们制作了一个简化应用。将该应用安装在上述最新设备上后，尝试两种语音识别方式均出现相同问题：

• 第一种方式报「未选择语音识别服务」
• 第二种方式报「绑定识别服务失败」

调试截图：

若无法解决此问题，我们的创业项目将无法启动POC。（注：所有库已更新至最新Android版本）

以下是简化应用的MainActivity.kt代码：
