In the source's own words

“Voice command system freezes when voice command is used immediately after ignition is ON”

T-SB-0117-19 Entune Audio Head Unit Software Update (Denso-Ten), Toyota Motor Sales, U.S.A., technical service bulletin, revision 1, 2019, Introduction, second list of conditions.

What it measures: Toyota's bulletin covers Entune head units with specific software versions, for 2014 model year Corolla and RAV4 vehicles with the listed Entune versions, and for other models in its applicability table.
What it does not show: This is one fault from a list for specific model years and software versions. It concerns the car's own voice commands, not dictation into a phone app. A different Toyota model or software version may not show it.
