  • *Introduction*

    Mandarin-English Code-Switching in South-East Asia was developed by Nanyang Technological University and Universiti Sains Malaysia in Singapore and Malaysia, respectively. It is comprised of approximately 192 hours of Mandarin-English code-switching speech from 156 speakers with associated transcripts.

    Code-switching refers to the practice of shifting between languages or language varieties during conversation. This corpus focuses on the shift between Mandarin and English by Malaysian and Singaporean speakers. Speakers engaged in unscripted conversations and interviews. In the conversational speech segments, two speakers conversed freely with each other. The interviews consisted of questions from an interviewer and answers from an interviewee; only the interviewee's speech was recorded. Topics discussed range from hobbies, friends, and daily activities.

    *Data*

    The speakers were gender-balanced (49.7% female, 50.3% male) and between 19 and 33 years of age. Over 60% of the speakers were Singaporean; the rest were Malaysian.

    The speech recordings were conducted in a quiet room using several microphones and recording devices. Details about the recording conditions are contained in the documentation provided with this release. The audio files in this corpus are 16KHz, 16-bit recordings in flac compressed wav format between 20 and 120 minutes in length.

    Selected segments of the audio recordings were transcribed. Most of those segments contain code-switching utterances. The transcription file for each audio file is stored in UTF-8 tab-separated text file format.

    *Samples*

    Please view this audio sample and transcript sample.

    *Updates*

    As of 12/14/2015, an additional set of transcription files were added for all the audio. The transcriptions are updated based on the original transcription, with adding the previously un-transcribed utterance. The language label also is also added for each utterance in the transcription. File directories were also changed to reflect the update, specifically, the change is made under /data/{recording_type}/transcript/{phase_number}/
    Where
    - the {recording_type} is equal to 'conversation' or 'interview'
    - the {phase_number} is equal to 'phaseI' or 'phaseII'
    +) 'phaseI' contains all the existing transcription from the first release
    +) 'phaseII' contains the newly updated transcriptions, where some typo mistakes, wrong boundary markers are corrected. Un-transcribed segments, which are normally monolingual and language label for each segment are added.

    The documentation for the corpus also updated to include the detail description on the new update in section 3) Transcription.
