你为什么要使用笔名？
我写书用的是笔名“元亨”。[{'character': '我', 'pinyin': 'uo2', 'highest pitch': 10.5, 'lowest pitch': 8.68, 'duration': 0.17, 'prosody hierarchy': '#1'}, {'character': '写', 'pinyin': 'xie3', 'highest pitch': 10.5, 'lowest pitch': 6.04, 'duration': 0.22, 'prosody hierarchy': 'null'}, {'character': '书', 'pinyin': 'shu1', 'highest pitch': 10.77, 'lowest pitch': 6.36, 'duration': 0.21, 'prosody hierarchy': '#1'}, {'character': '用', 'pinyin': 'iong4', 'highest pitch': 11.18, 'lowest pitch': 8.35, 'duration': 0.21, 'prosody hierarchy': 'null'}, {'character': '的', 'pinyin': 'de5', 'highest pitch': 8.35, 'lowest pitch': 6.81, 'duration': 0.1, 'prosody hierarchy': '#1'}, {'character': '是', 'pinyin': 'shiii4', 'highest pitch': 8.71, 'lowest pitch': 6.9, 'duration': 0.16, 'prosody hierarchy': '#1'}, {'character': '笔', 'pinyin': 'bi3', 'highest pitch': 7.34, 'lowest pitch': 5.23, 'duration': 0.2, 'prosody hierarchy': 'null'}, {'character': '名', 'pinyin': 'ming2', 'highest pitch': 8.83, 'lowest pitch': 5.23, 'duration': 0.35, 'prosody hierarchy': '#3'}, {'pinyin': 'sp1', 'highest pitch': 0.0, 'lowest pitch': 0.0, 'duration': 0.06}, {'character': '元', 'pinyin': 'van2', 'highest pitch': 8.73, 'lowest pitch': 6.48, 'duration': 0.18, 'prosody hierarchy': 'null'}, {'character': '亨', 'pinyin': 'heng1', 'highest pitch': 10.59, 'lowest pitch': 8.73, 'duration': 0.36, 'prosody hierarchy': '#4'}]
