When my father had his larynx removed,the only thing available was the battery-operated larynx. He didn't like that it made him sound like a robot - that was his personal prejudice. My father-in-law had used one for decades & was very comfortable with it. So, my father learned esophageal speech - very difficult, but he was also very determined. Basically, you swallow air & burp up sound. I met a man recently in the grocery store who either spoke esophageally (is there such a word) or had an internal device. He spoke well. HIs voice just sounded a little more gravelly than normal.
There will be a learning curve, but but you will be able to speak.See if there's a laryngectomee club in your area. They re great people & can help.
Good luck!
