Speech/speaking feature not working on MacBook
I am now using Sierra, and I have come by a few problems since. My speech feature was not working on my MacBook pro. I re-started my computer and I used the "take dictation" function which triggered the sound to activate. This prompted the "speaking" to start again. Note that the sound was working perfectly on my videos and other applications. Hope this helps!
