The main available options are: esophageal speeech, external devices eg Servox electrolarynx and tracheoesophageal valves. In my experience the best outcomes are with tracheoesophageal puncture withor without the hands free option. Speech is near normal and the learning curve is very rapid.
I agree with Professor Dr Badr eldein. TE prosthesis is the ideal solution . Oesophageal speech is an alternative when phoniateric units and speech therapists are available.
There are three ways. The oldest was with his own esophageal voice like a ventriloquist. The second is with the use of electronic larynxes, The new one is by a Tracheoesophageal puncture and voice prosthesis wich can be done as a first time duringe the surgery or a secondary procedure

The surgical technique involves the tracheo-esophageal speech by inserting prosthesis of which there are various kinds; Neoglottis; the use of laryngeal composite tissue transplant.
