Transcription Step 2 Instructions indicates:

When you’re running Dictation, your computer automatically mutes all audio that’s playing. To override this, you’ll need to run two commands in Terminal

I have performed the write-commands and read-commands:

user@users-Mac-mini ~ % defaults write com.apple.SpeechRecognitionCore AllowAudioDucking -bool NO
user@users-Mac-mini ~ % defaults read com.apple.SpeechRecognitionCore                       

{ AllowAudioDucking = 0; }

user@users-Mac-mini ~ % defaults write com.apple.speech.recognition.AppleSpeechRecognition.prefs DictationIMAllowAudioDucking -bool NO
user@users-Mac-mini ~ % defaults read com.apple.speech.recognition.AppleSpeechRecognition.prefs

{ DictationIMAllowAudioDucking = 0; DictationIMCorrectionCount = 0; DictationIMIntroMessagePresented = 1; DictationIMLastDictationDate = "619237426.7170759"; DictationIMMessageTracesSinceLastReport = 4; DictationIMSensedMicActivityState = 1; DictationIMSensedMicIdentifier = "SoundflowerEngine:0"; "DictationIMUpgradedTo10_15" = 1; }


  1. How to keep sound from muting while using dictation?
  2. Anyone: please to add relevant links


Reference 1 (above) indicates BASH commands overrides mute trigger in Mojave in 10.14.1

Audio drives the input level meter as expected:

enter image description here

A speech audio file is started. The text editor is opened: when Dictation is invoked, the input level meter goes dead (audio player automatically muted).


What can be done to diagnose why the BASH commands were not effective in disable automatic mute?

  • I was having the same issue but I wasn't aware of the audio muting commands. When I set it up I found that if I left the Dictation page of Preferences the muting issue happened. If I stayed there, it didn't! At the time I had my MBP connected to the TV via HDMI and I was using it like this for weeks. The TV is now gone and I had to restart my mac and my little trick isnt working nor are your anti-muting commands. :( I am sharing this in case it triggers something for someone...
