  • What can the WER tool be used for?
    The WER tool can be used to check the accuracy of the transcript that was automatically generated using Amberscript. You will need a 100% accurate version of the transcript as well as the transcript generated by Amberscript’s software. Simply upload the 100% accurate version in the left text box and the transcript generated using Amberscript in the right text box. The WER will be automatically calculated and displayed just above the two text boxes.
  • What is a WER (Word Error Rate)?
    The Word Error Rate (WER) is a measure of the performance of speech recognition technology. It is the percentage of words that is not correctly transformed from speech-to-text. The accuracy is thus 100% minus the WER.
