How it was built

  • Historical version of the speech corpus, used to train Whisper (F02).

The corpus, as charts

The three splits of the corpusThe splits are drawn by recording and not by segment: no audio is shared between training, validation and test. That is what makes the measurement honest.

Limits

  • Audio is shared between train and test: measurements made on this version are overstated. Use V3.2.

Protecting the speakers

The corpus holds human voices. It carries no name and no contact details. Seeking to identify speakers or to clone their voice is forbidden: that is a condition of access. To withdraw a recording, write to contact@congo-digital.com. Read the data governance.
