Dataset Summary

Swiss Parliaments Corpus, an Automatically Aligned Swiss German Speech to Standard German Text Corpus (Michel Plüss et. al.)

The inputs are a Swiss German audio recording of arbitrary length, e.g. in FLAC format, and the corresponding manual Standard German text transcript. The audio file is transcribed with Amazon Transcribe. The Amazon transcript is then globally aligned to the manual transcript using Biopython’s (Cock et al., 2009) PairwiseAligner. The manual transcript is split into sentences using spaCy (Honnibal and Montani, 2017). Each of these sentences is mapped to a start and end time in the recording via the global alignment and the per-word start and end times provided by Amazon Transcribe.
