We investigated the effects of voice training on subjective evaluation of voice. First, we collected 305 words which represent voice characteristics and narrowed them down to 10: ‘sweet’, ‘vivid’, ‘calm’, ‘pleasant’, ‘muffled’, ‘high-pitched’, ‘thin’, ‘husky’, ‘clear’, and ‘thick’, that would be used to evaluate voice characteristics. We then carried out a subjective evaluation experiment using these words for speeches of announcers, students who had received no training, and students who had received voice training (before, during, and after). We found that the voices of announcers were more intelligible than those of students, and that the voice of students with training became more intelligible as the training advanced.
