Speechalyzer: a tool for the daily work of a 'speech worker'.

For a first glance you might look at this presentation

I wrote a blog post on how to install Speechalyzer and Labeltool

NOTE: if you want to label data, you probably will need to use the 'Labeltool' project as well. it can be installed/downloaded here

It is optimized to process large speech data sets with respect to transcription, labeling and annotation. It is implemented as a client server based framework in Java and interfaces software for speech recognition, synthesis, speech classification and quality evaluation. The application is mainly the processing of training data for speech recognition and classification models and performing benchmarking tests on speech-to-text, text-to-speech and speech classification software systems. We also used it for listening experiments (labels can be hidden).

There's a paper describing Speechalyzer: F. Burkhardt: Fast Labeling and Transcription with the Speechalyzer Toolkit, Proc. LREC, 2012

Speechalyzer is divided into two projects.

  1. Server: Speechalyzer.jar is the server program and maintains the audio files and does batch processing.
  2. Client: Labeltool.jar is a client program to use a GUI for labeling and annotation.

USAGE: Here's what you would to to label/annotate some speech files. 1.) adapt the res/ file at least to the audio format 2.) put the audio files in the 'recordings' directory (or provide a file list with pathes) 3.) start the Speechalyzer: java -jar speechalyzer.jar 4.) start the Labeltool: java -jar labeltool.jar 5.) label/annotate the speech files 6.) the things you did will immediately be stored into text files having the same name and path as the audio files

Not included, but with provided interfaces are third party Speech softwares: Acoustic Feature Extraction Praat, openEar, openSmile Classification: WEKA Text-to-Speech Nuance, Svox, Ivona, Mbrola, Mary Speech-to-Text Nuance Speech server Evaluation NIST WER calculation

If you want to compile, you will also need the 'FelixUtil' project (beneath other open-source libraries).
