Depend on how long s: Voice changes expected following any surgical procedure, requiring general anesthesia ، this usually result from throat and laryngeal irritation from anesthesia tube (endotracheal tube), usually transient and last few days. In regard to thyroid surgery, specifically there is always risk of laryngeal nerve injury, which result in voice changes, this can be permanent or temporary.

It can happen: Hoarseness may result from the endotracheal tube resting in your throat during the surgery. Also a thyroidectomy requires dissection of the recurrent laryngeal nerves/superior laryngeal nerves. These nerves control your vocal cords. If they are stretched, bruised, or injured during surgery, you may have some hoarseness. This usually resolves. If hoarseness persists, talk to your surgeon.
