ASCEND: A Spontaneous Chinese-English Dataset for Code-switching in Multi-turn Conversation

Understand

Code-switching is a speech phenomenon occurring when a speaker switches language during a conversation.

• Despite the spontaneous nature of code-switching in conversational spoken language, most existing works collect code-switching data from read speech instead of spontaneous speech.
• ASCEND (A Spontaneous Chinese-English Dataset) is a high-quality Mandarin Chinese-English code-switching corpus built on spontaneous multi-turn conversational dialogue sources collected in Hong Kong.
• We report ASCEND's design and procedure for collecting the speech data, including annotations.
