Voice Recognition for Toyota Highlander

Try, as chase said, to speak to the machine… like a machine.
“voice recognition” often doesn’t recognize some heavy accents of english like a heavy southern drawl, east Indian, thick mexican/spanish etc.
Too many words too close together also is confusing to the machine.

If not, call the help line.
Even if that one isn’t the one for your issues they’ll tell you the next step.
