This workflow shows the functionality of the KNIME Audio nodes in combination with Text Mining. The example audio file contains a one minute sample of an audio book of Alice's Adventures in Wonderland by Lewis Carroll. - Read in audio files - Use speech-to-text services - Use text mining to see which speech-to-text service delivers the best results NOTE: - The CMUSphinx4 speech recognition service does not require any credentials - Bing and IBM Watson require access to the respective services and the corresponding credentials
