The Thematic Speech Recognizer is provided for the CLARIN VLO. The service allows a user to receive a detailed analysis of the audio recording spectrogram to identify periods of voice activity and the intervals between them. It is possible to obtain results (a list of periods of voice activity or pauses with an indication of time with an accuracy of 10 milliseconds) in the form of subtitles or tags for the Audacity program.
