title: Flutter: Voice Detection Trigger Phrase
body: <p>I am currently using the <a href="https://pub.dev/packages/speech_to_text" rel="nofollow noreferrer">speech_to_text</a> package to add voice control to my Flutter app. This voice detection <strong>is triggered by a button click</strong>.</p>
  <p>Is there any way to trigger the voice detection when the user says a certain phrase similiar to <strong>&quot;Hey Google&quot;</strong> instead of having to press the button every time?
  The library itself does not provide a way to add a &quot;standby detection&quot; mode and continous detection is not supported. Other ideas on how to circumnavigate this additional click are also welcome.</p>
  <p>If your answer includes a library it would be great if it is free or has a free plan. This would really boost the user experience a lot. Thanks.</p>
