Thanks for the query.
It will take some more time to show symptomatic relief by the antibiotics. Continue the antibiotics and do not stop them. Meanwhile give rest to your voice and avoid cold items like chilled beverages, ice creams, etc. Have hot things instead like hot milk, coffee, etc. Also, warm saline gargles 3 times a day is helpful and drink plenty of water daily. Chewing of lozenges with ginger and lime can help as well. Steam inhalations also are of great use.
Hope this helped.
