Objective To investigate whether wearing hearing aids in children with unilateral cochlear implant can improve their emotional intonation recognition and whether different intonation recognition is differ in recognition. Methods Thirty-five children（15 males and 20 females） with severe and extremely severe sensorineural hearing loss in binaural bimodal hearing were selected to compare the emotional intonation recognition characteristics in the two hearing modes（unilateral cochlear and binaural bimodal hearing mode）. Results The intonation score of the children in binaural bimodal mode was higher than that in unilateral cochlear implant mode（P<0.01）

and the recognition rate was improved by 16.65%. The happy intonation increased by 20.59%

the angry intonation increased by 19.21%

and the sad intonation increased by 13.23%. Individual data analysis found that 82.85% of the children showed binaural bimodal advantage. The recognition score of angry intonation was significantly higher than that of happy and sad（P<0.05）. In the binaural bimodal hearing mode

23.53% of children perceived happy intonation as sad

and 22.79% of children perceived sad intonation as happy.Conclusion Compared with unilateral cochlear hearing mode

children can gain the advantage of emotional intonation perception through binaural bimodal hearing. The recognition of angry intonation was easier than that of happy and sad on the two modes

the happy and sad intonations were easily confused. Frequency variation may be the important cues for emotional intonation perception based on the analysis of acoustic materials

which should be highlighted in the rehabilitation process.
