很难算出准确时间的。[{'character': '很', 'pinyin': 'hen3', 'highest pitch': 9.0, 'lowest pitch': 7.43, 'duration': 0.19, 'prosody hierarchy': 'null'}, {'character': '难', 'pinyin': 'nan2', 'highest pitch': 9.33, 'lowest pitch': 6.43, 'duration': 0.21, 'prosody hierarchy': '#1'}, {'character': '算', 'pinyin': 'suan4', 'highest pitch': 11.58, 'lowest pitch': 8.98, 'duration': 0.22, 'prosody hierarchy': 'null'}, {'character': '出', 'pinyin': 'chu1', 'highest pitch': 9.26, 'lowest pitch': 8.47, 'duration': 0.19, 'prosody hierarchy': '#1'}, {'character': '准', 'pinyin': 'zhuen3', 'highest pitch': 9.24, 'lowest pitch': 5.35, 'duration': 0.18, 'prosody hierarchy': 'null'}, {'character': '确', 'pinyin': 'qve4', 'highest pitch': 8.0, 'lowest pitch': 5.88, 'duration': 0.18, 'prosody hierarchy': '#1'}, {'character': '时', 'pinyin': 'shiii2', 'highest pitch': 6.75, 'lowest pitch': 6.37, 'duration': 0.18, 'prosody hierarchy': 'null'}, {'character': '间', 'pinyin': 'jian1', 'highest pitch': 8.41, 'lowest pitch': 6.37, 'duration': 0.27, 'prosody hierarchy': 'null'}, {'character': '的', 'pinyin': 'de5', 'highest pitch': 8.16, 'lowest pitch': 5.56, 'duration': 0.21, 'prosody hierarchy': '#4'}]
