Now that he has converted to the inhalation method, the progress is just great. Of course Mr. A's efforts are to be counted. I regret for not having given him the advice in earlier stage.
The opposite case of Mr. B; he was taught the inhalation method thoroughly from the beginning. In less than four months' training, he was able to speak fluently, and now he feels no inconvenience in daily conversation. Far from it, he also sings songs to his colleagues' astonishment.
He had never thought of improving his esophageal speech with such a speed and he sometimes forgot that he was a laryngectomee to the extent that he made quarrelling with his wife unconsciously. He finds himself enjoying his life contentedly.
