语音识别中的果冻豆蜂鸣声

概述我一直在研究不同的线程,但是没有发现任何对我遇到的问题有用的东西.我想摆脱语音识别开始时发出的“哔”声.我正在使用JellyBean4.2.2,因此不确定在早期版本中是否存在相同的问题,如果我也想解决此问题.另外,我想知道是否有人对如何响应某些语音识别结果提出建议.请让我知道我的

我一直在研究不同的线程,但是没有发现任何对我遇到的问题有用的东西.我想摆脱语音识别开始时发出的“哔”声.我正在使用Jelly Bean 4.2.2,因此不确定在早期版本中是否存在相同的问题,如果我也想解决此问题.另外,我想知道是否有人对如何响应某些语音识别结果提出建议.请让我知道我的代码如何即兴包含这些功能.
