Smoking Hot Phonemes /θænk ju:/

From a 22 Words post titled "Phonetically Accurate Gratitude"

“OK, so it’s actually not quite accurate since the T-H is voiced in “than” but not in “thank,” but close enough.”

I love that 22 Words noticed the voicing.

theta is voiceless

eth is voiced

To add further phonetic analysis, the way the sign is written the individual words would read as /ðæn/ and /kju:/
when in reality the expression of gratitude is a combination of the words
/θænk/ and /ju:/
