We have been waiting for more than 3 years of Turkish Language add-in.
İf it does not support Turkish languages it's not a usable device in this country.
We look forward to your support on this matter as soon as possible. As you know, Google Assistant can now speak Turkish on phones. The fact that he can't talk on this device isn't very revealing.
Thanks for visiting the Community.
We're glad you're interested in adding the Turkish language in the Google Home app. Our team is continuously working on adding more languages and we'll take this as feedback. Please let us know if you have any other questions or concerns as I will be locking this in 24 hours.
