corespeechd is sending a massive amount to data to Internet. Why?

On a brand new Mac Mini 2018 with Mojave, I've noticed in Activity Monitor the corespeechd process is , even without a connected microphone, and with Ask Siri disabled, sending a large amount of data out and consuming network resources. Why? corespeechd is an Apple process part of the CoreSpeech.framework, but that's all I could find out.


If you have Mojave, could you open Activity Monitor and see if you have the same issue, and let me know?

I can confirm the fix for me


1. System Preferences -> Accessibility -> Siri

2. Click “Open Siri Preferences...”

3. Check the box for “Enable Ask Siri”

4. Move the radio button for “Voice Feedback” to “Off”

5. Uncheck “Enable Ask Siri”


No more packets sent, network graph is flat lined.
