This issue tracks adding a feature to support speech recognition powered by Apple. Since it would require sending data to Apple's servers, this should not be enabled by default and should require a flag.
Also, the current error: ERROR: Speech recognizer does not support on-device recognition is not too descriptive. It could be revised to include more context or suggest the proposed flag.
