voice-recognition: Mobile phone stops listening even with the "continuous" attribute

[masonlouchart]

On my app, I have a button to start and stop voice recognition.

("Parlez" = "Speak now")

The purpose is simply to fill an input form. On browser everything is working well. The user starts and stops the audio capture when they wants.

On my Nexus 5, the mobile phone itself stops the capture. Moreover, the end event is not thrown and the result event is twice. As the app is waiting for end event to update the button style, it's never updated.

Current behaviors

• mobile phone stops the audio capture even when continuous attribute is true
• result event is fired twice when mobile phone stops the capture

Expected behaviors

• mobile phone records the voice continuously when continuous attribute is true
• result event fired only once
