Location of Voice Memos transcripts in the file system?

Where are the transcripts that are generated from recordings in the Voice Memos app stored in the file system? I did a:

grep -r PATTERN ~/Library`

for a known unique-ish pattern from one of the transcripts. It's been running for 45 minutes and hasn't found any matches yet. The audio recordings (*.m4a) and *.waveform files are stored here: ~/Library/Group\ Containers/group.com.apple.VoiceMemos.shared/Recordings/ I noticed a CloudRecordings.db sqlite database file (binary) in that directory, and none of the table names look obviously transcript-specific. I did the same grep command in this directory, and it completed and didn't find any matches.

$ sqlite3 -readonly ~/Library/Group\ Containers/group.com.apple.VoiceMemos.shared/Recordings/CloudRecordings.db .tables

I also did a: find ~/Library/ -iname '*transcript*' which returned 100 filenames/dirnames. One that looked maybe related was: /Users/robbednark/Library//Accessibility/com.apple.RTTTranscripts.sqlite Nothing obviously transcription-related in those table names either, and grep -r PATTERN ~/Library/Accessibility completed without any matches.
