Ever feel that Amazon's Alexa voice assistant can be a bit too chatty for its own good? A new mode in testing could help the digital helper bite its tongue at appropriate moments on your Amazon Echo device.

Some Reddit users (as reported by AFTV News) are being offered a new beta "Brief Mode" to try in the Alexa app. This replaces spoken responses for simple beeps when some tasks have been completed.
