How can I fix high CPU usage by corespeechd on MacBook Pro?

After using my MacBook for a while, I notice that the corespeechd process starts consuming over 100% of the CPU. I don't use Siri or Dictation, so which programs should I suspect? If there is a permanent and safe way to fix this issue, I would like to know.

old issue, new issue, what changed?


dictation and speech recognition capabilities if you're using headphones with a built-in microphone or AirPod..., your Mac will begin to recognize and process your voice....
