Microphone mute notification with voice activity detection

A method for notifying a user of a mute state of a primary microphone arranged to capture the user's speech during a call with one or more other participants, in case the user speaks while the primary microphone of the microphone system is muted, the method comprising:

• 1) performing a noise cancellation algorithm by processing output signals from the primary microphone and output signals from an additional microphone located to capture sound from the user's surroundings to suppress surrounding noise,
• 2) processing output signals from the primary microphone according to a Voice Activity Detection algorithm by means of a processor system while the primary microphone is muted,
• 3) determining if speech is present in accordance with an output of the Voice Activity Detection algorithm,
• 4) determining if an additional condition is fulfilled, and
• 5) providing a mute state notification to the user only if it is determined that speech is present and the additional condition is fulfilled.
