Emotion recognition and language discrimination is it easier to judge emotion from mother tongue than foreign language?

摘要

Japanese and English native listening subjects identified speaker's emotion (Task 1) and native language (Task 2) for utterances, "pikachu", which Japanese and American children generated with happy, sad, angry, surprised and neutral feelings. In the both tasks, the correct identification rate was higher for utterances by Japanese child speakers than those by Americans regardless of listener's language. The correct identification rate of neutral utterances depended on the mother tongue of speakers and listeners. Utterances with angry, happy and neutral emotion were more accurately identified than those with happy and surprised emotion. Neutral utterances provided a higher language identification rate than emotional utterances. These results suggested that the language specific characteristics are less in the emotional utterances than neutral utterances.
