This paper proposes a speaker diarization method for face-to-face dialogue of service counters using appearance pattern of speakers. In face-to-face dialog by a customer and an agent at service counters such as mobile phone shops and bank tellers, overlapping speech often occurs and makes speaker diarization difficult. To achieve an accurate diarization, our proposed method utilizes appearance pattern of speakers. Taking into account that agents do not frequently change their places, final agent-speaker labels are decided using context of estimated speaker labels. With customers, a customer only talks to a single agent and does not appear twice or more times in a day in most cases. Therefore, the proposed method first estimates segments of agents and then clustering of the customer speeches is applied to each of the segments, in which the clustering is performed so that near speeches are clustered in the same cluster. Consequently, our proposed method achieves 12.9% of diarization error rate on the simulated dialogue data of service counters of mobile phone shops. |
